- In depth review of the RCF SUB905AS II 15" subwoofer from RCF. Another in the take it apart series. This is a mighty power house 15" 1100WRMS subwoofer that is a new addition to the RCF SUB Series line up.
Your video angle very GOOD, zooming GOOD , easy to understand, Great ! Thanks.
Congratulations on your demonstration as always is great.
Superb video content as always! Thank you trinityprosound from England :)
Thank you for watching !
Rcf is way better than those kw 181s
Thank you, great work and fantastic review. We want to test the 905II. Still another issue is: Wich Cam you use for this video? It looks so good, the dynamic is professional and the af ist perfect.
We use CANON XC10 and shoot HD at 60fps
Thanx
I don't like the 181s either. The RCF 705s are nice and lightweight. I haven't listened to the 905s yet. the 708s are nice too but heavier.
And one more thing 😊 may you should try too one of the rcf705as so we could see the inside thanks
We will see if they can send us one to demo.
We got this sub for new year! Sounds great -10 H2 maybe H3 different songs sound better
Why did you drop them by -10db, i ask because i bought a pair only to find 905s clipped pretty quickly, i used a pair of ART 312MK4s on top (1 sub 1 top)
you never want to run the input gain fully open on a speaker as it will limit very quickly as it over drivers the input gain section on the amplifier, that is not a volume control but an input sensitivity control ,we will run most 4 to 10 db down depending on model to get the best results. set your ART boxes at 12 o'clock position or 2 o'clock and work with the subs so that they both limit at the same time for volume and use a crossover point of around 100-120hz to send up to the 312's, we never run full open with the input sensitivity all the way up. yes, it will clip early
thanks for the reply, i have been playing around with your tip today and yes the sheer output of the bass now appears to be more matched to the 312, i make some further tests this weekend
trinityprosound is it soft clip? Is it true the woofer needs to break itself in cone?
Donna Webber what do the mk4 sound like now?
Looking for RCF SUB 905AS II settings in combination with HD32MK4?
I would use H3 or H4 and come out of the sub to the HD32 from the xover output- but you have to push in the xover button for output rather than link
Would one of these (to start with) be a good match with a pair of art 712-a mk2 speakers? Which crossover settings would be preferred? As I understand these subwoofers are louder when using the H presets instead of the L ones. Cheers and thanks for good videos.
The 905 is a great 15" sub. and yes will work with the ART series no issues. Depending on what you are using it for and music etc. since it is a 15" don't anticipate you are going to be getting the same response as an 18" with larger volume cabinet, but for the size the 905 does a great job. Its sweet spot for output is going to be 60-100hz, going below 60 and expecting same output won't happen. Going to be a quite a reduction in output volume.
Alludes brother Trinity wanted to ask you a question between elsub RCF 905AS II, RCF 705AS II and the DB DVA s09DP which sounds better and strong in open spaces? Thank you
it would have to the the 905AS2...most power and best DSP
Is there a sound difference between 905as and 905as II? I have one 905as and now I am in doubt should I get one more 905as or 905as II?
Is it better to have two 905as or one 8003as?
Yes there is a difference, will you notice it, most likely not...IMO better to have 2 of the 905AS than a single 18....
Hi, which is the best art top to go with 905 as 2, how about art 715
i would do the ART732 for coupling with that sub....smooth transition and fantastic HF driver with lower cross over point.
Fantastic video...can you help me .I'm using the sub on l2 linked to 2 rcf hd32a tops.
I find the sound a bit mushy and not clean any ideas on best settings for my configuration.
I have my tops set on 2 ie 10 past..
Cheers
H2 40 Hz - 80 Hz
H3 40 Hz - 100 Hz
anything in the 30hz area is going to overdrive them and they really are not meant to be pushed down to 30hz
for volume sensitivity, wide open
Hi there, I was checking 708 and 905, and find out that they both have 133dB output, and 708 is 700w amp, and 905 is 1100w amp. I expected they will have almost same output, and ofc, more low end in 708 (coz 18"), but, in live, I can bearly hear 905 against 708.
Did I expect to much from 905, or there is some "catch" with input gain? (I use xair18, and set up is 80Hz xover on 708, and L2 presset on 905 + didn't notice much difference with H2 presset)
the 708 being an 18" is going to give you more low end due to larger cabinet and speaker surface... the 905 being a 15" does a great job for a 15" sub, we installed 2 in a church gym and was impressed with the 15's but they are not 18s. best 15's we have ever heard is the RcF TTS26's dual 15" subs, but they are $5000 each... the 905 being a compact sub, in reviewing the specs vs. the 708 shows it goes lower, but it is the volume of the box and the surface of the 18" vs. 15" that you are hearing the difference, or lack thereof from the higher powered 905. in the case of subwoofers, size does matter.
@@trinityprosound is it better to go for one more 905, or change to 1x8004?
if you can do the size of the 8004 is my choice, if the size and transportabily is the issue get another 905 and put them side by side to couple on the floor if that is possible.
Which is the better Sub 905as ii or 708 as ii ?? Please advice am going to buy one of these two..
I would do the 708 18" vs. the 15, even though the 905 has more power the 15" driver does a great job, but as with most 15" subs unless you get one that is $$$$ and 18 IMO does a better job and has lower freq. response and "moves more air" IMO that a 15. We installed a pair of them in a small gym under the stage and they did a great job, but 18's always win and the 708 will kill a comparable (using that term loosely) QSC
what is the best (sound and sound pressure) between rcf 905as2 and db 15h? and which one has a better quality / price ratio?
the 905 wins, but at almost 1.5x the price.905 has more DSP settings and better build quality with cabinet, etc.
905as vs nxl44a top ok??
The NXL44 top will out run the 905 really quick, you will need like 8004 or 8006 sub with that top box and the 3 x 10" drivers in it...
Hello! Very nice review. Why they don't own a power on/off switch? Is this good or bad? Thank you!
Some of their speakers do not incorporate, not sure why, but one less thing to break and also one less thing to accidentally get turned off by mistake....
I just got one of these and 2 of the 712 mk4 tops, man these things rock for 15" subs, really impressive, do you have any suggestions for the best settings for this combo, at the moment I have them on H3 with -10db and 0 delay, the limiter light does flash early, but I was told that's not a problem, just an indication they are at 0db, hopefully that's true.
Now to save up for a second sub ;-)
sounds like you have setup ok...i would use H2, just use the built in crossover at 90Hz up to your top boxes.
@@trinityprosound The limiter light flashing is nothing to worry about to much I hope ? I hear great things about the limiter protection in RCF box's and that there almost impossible to blow up, what's your views on this?
it can flash, just not on steady, they do have great protection, but if you are driving it that hard that the limiter is coming on you need more subs, you don't have enough rig for your gig.
Hi, there, just a quick question, in a two sub cardioid setup, as the manual says, which one should be facing forward the top or the bottom one?
either one, but i would do the top facing rearward and let the bottom one couple to the floor.
I own a pair of tt25a 11,s and want to add a sub, the 8003’s are a bit big & heavy, would the 905as11 be ok ? Only play small to medium size pubs /clubs. Mainly want to put some sub away from the tops and hopefully create a bit more space in the mix, cheers, Andy
yes they 905 would be "OK" for a 15" sub and the power behind them , they do a good job. we installed a pair into a church gym for their youth group and was quite amazed with the output of the pair.
Amazing review like always. We have used this sub in the last few months quite a bit and it's amazing paired with the sub8003as II. Two of these subs on on H2 and the sub8003as II on L2 is just amazing. I'm just curious about the new TTS15-A. It's the same 1100w amplifier, 15inch driver and about the same size, and 1 db higher. But the price is also much higher...So i'm wondering..is it worth the upgrade? Do you have an opinion on the TTS15-A?
It's the first sub from the TT line with a 3inch voice coil..Even the older tts12a had a 4inch voice coil..That's why I'm worried
It may have the driver from the TTS26A subs and not the same as this being a stamped basket and ceramic magnet. The footprint fo the amp looks similar, but would have to confirm with RCF on the amp, that would be a shame to use the same amp on both speakers, the TT being a premium line. We have the TTS26A subs and for a dual 15" they are killer. I have not heard on the TTS15 and most likely being so new we won't see here in the USA for a bit .. RCF has been doing some amazing thinks with small VC as with the new 9007 subs being 21" with small VC for faster reaction time of the driver. For a 15" I have no issues with a 3" VC vs. 4" .... as long as the driver does the claimed power rating and won't destroy itself under operation/load.
Did you get good results from this set up ? the 905 set at H2 and the 8003 ON L2, did you suffer from "coupling" issues ?
Hello, I have 2 questions for you! I own a PRX 818 xlfw subwoofer, but I'm thinking of changing my system to RCF! Would it be better to replace it with RCF 905 AS II and would it be better to use pair art 735mk4 with one subwoofer 905 AS II?
I would keep the subs you have and couple up with the 735's , the 905 is a good 15, but won't quite do what an 18" sub will do. The 818 sub is more like the RCF 708 sub in features and power. So you should have no issues. Use the high pass on the subs "80Hz 24dB/Octave high-pass filter is applied to the signal coming out of the THRU connector" and you will have a great sounding system.
How can I get the software for the test tutorials
Have to purchase from SMAART www.rationalacoustics.com/smaart/about-smaart/
How do these compare to the QSC KW181?
They will do everything a 181 will do in a 15" speaker. 181's are really marginal subs IMO , there is so much more out there that does a much better job sound quality wise....
Hello. I own some TTS26A subs and I also own 2 backup drivers for them. (Lf15n401 on 4ohms). I also own some 705/905as subs and I want to put the LF15N401 inside them. Replace the factory drivers. What do you think? Will there be a significant difference? What do you know about the impendance on 705/905 subs? Is 4 or 8 ohms? Thank you!
I would not , the drivers are specific to the tuning of the cabinets and may not work well at all.
Hi. What settings to use with art 715a? Gain and xover
Gain would be noon to 3 o'clock no higher . cross over at 90hz no low end boost.
What are your thoughts comparing RCF 705/708 subs compared to DB Technologies Sub15H/18H? Thanks
Similar, but the RCF units have a bit better box construction in the materials. The db's are hybrid type with the H where the RCF are bass reflex design while the db is bass reflex and semi horn loaded , db's have a bit more power behind them in the amp on the 18" model.
My rcf 115 has the yellow mute light on.what shd I do
That is an amplifier failure and will need factory service
I have the 8004 under my tt22a mk2 , is the 8003 mk2 good to?
8003 is great, updated DSP and control, a wee less power but a new design overall.
Are you doing a review on the new evox j8 and jmix 8 any time soon ???
Yes one is on the way to us....
hi
i have a request, I'm just ready to buy a pair of RCF HD10-A MKIV. For one sub (but with the idea to maybe buy a second one later) I have the choice for the same price with a new RCF SUB 702-AS II and a second hand RCF SUB 905-AS II. My question is yes the 905 is a bit louder and powerfull (great) BUT, is it a 15' inch sub (or a pair) a good sound profile with my pair of HD10 ?
Thank you really much
Romain
Get the 905AS2 you will like it much better and has a ton of power, we have sold a lot of the 905 and people can't believe the output of the 905AS2
In fact it was the 905 AS (MK1). I took it, waiting finally for a pair of HD 12-A MKIV
Hello
How much delay does 2 and 3 modules use for L2 (80hz) and L3 (100hz) settings?
since they are small, 2-3 MS and 180 degree phase reversal on the rear facing sub for cardioid setup
@@trinityprosound Thanks
Hi, I have a pair of 905s and a pair of rcf 715-a mk4, what gain on the sub and what preset would work the best. I had the old 905s and these ones don’t seem as loud
start wide open, the DSP is not the same as the old units. I believe they are wide open when shipped "0", you reduce from there on the rotary encoder.
trinityprosound no I have the 905-as mk2 just wondering what preset and volume should I do with the rcf 715-a mk4
?
How does the delay work? If sub behind tops or front ?
The delay is going to be used for cardioid type sub set up. typically with aligned tops to subs, you would not delay that kind of deployment.
I haven't heard much about RCF until just recently. I'm looking for some advice. I do over 100 events a year, so I want something that is versatile, reliable, and has good power for large events. I currently have 4 SRX815P tops, and 2 SRX818SP subs. I was thinking of selling 2 of the tops and buying 2 K12.2's for those smaller events, but also be able to use them along side my rig for larger setups.
Hows does RCF compare to the SRX series?
Should I get the k12.2's or what would be an alternative?
I would even consider selling my whole rig and get RCF's if they are better. I'm just not sure they will be.
Don't waste your money on the K12.2, look at the RCF HD12 or HD32 and for subs if you want something killer the RCF 8004's. If you can swing the HD32 for $$$ you will be amazed at the sound output , sonic quality of the system.
@@trinityprosound Hello, hope all is going super! I have 2 JBL SRX828SP, do you think with 2 RCF 905-ASII will sound almost alike as the SRX828's?
no, it might be close, but the 828 is a dual 18 sub. you would have to go with a 8006 to compare sound and output. maybe if you put 905 side by side so they can couple , but with the large volume of a dual 18 box it is tough for a single 15 or a set of single 15 to come close unless you would look at the RCF TTS26A, but those are quite expensive but OMG amazing for a dual 15 sub
which is better than qsc kw 181 or rcf 905 as
we would have to compare the 708 to the 181 and i will take the 708 any day...
Hi buddy, thank you for the good detailed inside info. Looking to add some subs to my 745as II but struggling to choose between the 705asii and the 905ASII. Which would you recommended between the two and why please? Is there masses of difference to warranty spending the extra dosh on the 905s. Please help. TIA
do you need a 15" for size or weight? how are you going to use them, in pairs one on each side ? for the 745's would really recommend an 18" sub like the 8003 or 8004 for good solid low end.
Hi thank you for your reply. I was going with the 15s for weight and size mostly. Whqt is the different between the 8004 and 8003? Is there an ASII in any of these and would they be better? Thank u
Oh and intending to stack one on each side and for weddings mostly. 150-200 peeps. Also looking to purchase a set of DB Ingenia IT2T to use as an array.... do you think these will work well together on a pair of 18s plz. Thanks
The 8003 is a V2 model with newer DSP in it...less power than the 8004.
if you do one on each side with the IG2T tops, that will do a very good job, it is that the 15's won't go as LOW as the 18's but the 905 for a 15" sub does a good job for the size of that speaker. using the built in crossover of the subwoofer you can run the IG2T harder and let the sub do what it needs to.
Buen día veo que usted conoce mucho de estos equipos quisiera saber si los parlantes que van en las cajas art 715a mk4 hasta la art 745 a mk4 son parlantes italianos o es de China... Espero me pueda responder con la verdad gracias.
Buena pregunta. Todos los altavoces que hemos separado hasta ahora en la línea ART son todos los controladores RCF de Italia. Pero ha pasado más de un año desde entonces y sinceramente no estoy seguro de si algo ha cambiado en mfr. e importar drivers Hasta donde yo sé, el ART todavía se hará en Italia via Google Translate
yo vivo en Italia y te aseguro que todavía no las han vendido a los chinos así que quedese tranquilo . saludos.
Please,do a review about 8003 As MK II Sub ,i want buy them but i cant to decide :D
8003 vs. 905AS2 ? get the 8003 just like the 8004 but a wee less power but better DSP
@@trinityprosound all review about 8003 ? like this video ? :)
and are better 8003as Mkii then 905as MKII ?
yes, i will take a 18" sub any day over a 15" sub in this class/power
buenas me podrías ayudar con varias preguntas que tengo yo tengo un par de rcf sub 705 as ll creo que son bajos réflex, los bajos anteriores a este modelo son band pass, me podrías decir cuál es diferencia entre estos dos tipos de bajos, cual es mejor y cual se escucha más fuerte. y la otra pregunta crees que tengan casi los mismos componentes por dentro mis bajos sub 705 as ll y el 905 que estás explicando en el vídeo. y otra cosa estaría genial hagas un review del bajo rcf sub 705 as ll en español estaría excelente saludos
www.diysubwoofers.org/bnd/ and www.diysubwoofers.org/prt/ desafortunadamente solo en inglés, pero si puedes hacer que alguien traduzca es una buena lectura de las diferencias de los hablantes.
trinityprosound muchas gracias por tu respuesta saludos cordiales
What about this sub with rcf art 712 ? Has ist enough power?
Yes the ART712 would pair up really well with the 905 sub. For a 15" it does have a lot of get up and go ! Everyone that has purchased the 905 is quite amazed that it is a 15" subwoofer.
may i convert that speaker into mid bass woofer and i use it as my flyable woofer for line array,?
no. it is not constructed to fly, you will need a S09 or KS10 sub to fly RCF does not have flyable subs in their SUB line up... only in TT series. so look at db technologies for that...
trinityprosound thank you so much sir.. have a good day and more power to your channel.
Would love to see a components break down on the JBL PRX 818XLF
We are not JBL dealers and there is a reason for that ... over priced for what you get in return... not what they used to be...so many better options now
Hi I’m am interested in the 8004 vs 8005. Which sub is best overall?
I would have to go with the 8004 as best all around. The 8005 is good, but we have sold more 8004's than any other single 18" subwoofer and all who have purchase love them. Same power in the 8005, but you are moving a larger driver with the same power as the 8004.
trinityprosound thank you!!
knowing how you feel about QSC i dont suppose you would recommend pairing the qsc ks212 with rcf 745s ? the cardiod aspect appeals but not sure its compatible for the qsc needs the 745s to have a high pass filter i dont think it has ...any opinions or facts ?
if no crossover out , you would be running full range and that defeats the purpose of a dedicated sub. 8003 or 8004 would be the recommendation or the 15's in the 705 or 905 series
@@trinityprosound i have gone for a single rcf 8003 as ii now good choice ? hope so !!
I think you will be very pleased with the 8003 for sure
@@trinityprosound thank you any recommended settings o the dsp and xlrs ?
cross over at 90hz-100hz and use the xlr outs to your top boxes , set the button to xover mode and not link mode
I currently own the 705ASII. How much of a difference in output would I hear if I upgraded to these 905ASII? (Obviously an 8004 would be a huge upgrade but I currently need a smaller sub for weight reasons).
It drives a bit harder due to additional power, but you would be better off adding more 705s to your rig/system, yes 8004 would be the best option, but if you are looking to replace a 705 with a 905, not sure you are going to notice "that much" difference
Thank you that’s helpful! Is there any subwoofer in the “under 70lb” weight class you would recommend that would make a substantial difference over the 705?
db tech has a SUB15H that is decent for the weight, $$$ and output...hate to steer away from RCF but those are fairly portable and do a decent job.
Interesting! Same wattage but 2DB more max output...do you think they make a substantial difference over the 705ASII? The DB sub is 20lbs heavier but I wouldn’t mind if they were that much louder
i really don't think you are going to "hear" a difference in them IMO, they both do good for a 15" sub , all those subs are within a few pounds of each other...there is not 20lbs difference between the 15H, 705 and 905 69, 63, 66 respectively - we have the 15H in rental inventory and they do a great job for a 15, but i would use 705 or 905's if we had them...
question, How is the rcf sub 705-asMk11 stock up against the ev ekx -15sp would like to hear your opinion.
Have not heard the EV sub and currently not dealers, but not a huge EV fan either. I have seen their speakers and feel they are done on the cheap vs. what we have seen and used from RCF.
thanks.
Im pretty sure you have tom compare this to the EV ETX 15sp instead, as it is more the same price range and power range
would 2 of these match ok with my 745s..the 8003s etc are too heavy for me these days .and im.wanting to add subs just using 745s on their own at moment.
The 905 is a good 15" sub and has a lot of power behind it...it does do a good job, but i like the 18" 8003 or 8004 better for good low end. But if weight is an issue the 905's will do a decent job. We installed 2 in a school multi use room under the stage and was quite impressed with the output of them. They are a solid 15" subwoofer. Depending on what you are using them for , live vs. DJ ? they should provide you with sufficient low end to do what the 745's can not do. Use the built in cross over of the 905 and set at 90hz to the top 745's and it will give you a great transition from sub to top box.
@@trinityprosound they are to use in a vocal duo with playback singing pop / rock commercial covers , would they do that job ok ?
yes, sure will !
hi another possibility advice needed ..
been offered a single RCF TT 15a ii sub at a good price ....could that work with 2 x 745s , couldnt afford 2 TTs maybe later .
yes for a start it sure will....
could someone tell me what woofer model mounts? "product code"
It is a proprietary woofer unit , not in the regular speaker line up for sale. you could order one as a spare part, would have to inquire from RCF ...
could i get away with one 9005as ii with my 745s , space in car is a problem with 2 and the 8003s are a little heavy .
yes, but, the 745's will out run the sub for sure...but it will certainly give you a better low end than just the 745's
so the 8003 as ii would be a lot better ?
is the 8003 aasii on its own a lot better than the 905as ii?
yes it would , larger driver, larger volume of box , better low end IMO
do you think this it's a good option with a pair of rcf art 312 a mk11 for 200 people open space ???? nice .
yes, that combination would be very nice and sound fantastic. lots of sub for a 312 or pair, but 2 subs would be the best solution
trinityprosound thanks for your answer ..but if I take a 708 ass 11 wich is an 18 woofer and not the 905 ???? have a good day master .
not as much power only 700 watts and 905 is 900watts RMS but 708 is good sub for power and cost.
Great video... i would like to know if you have used the 708mk2 and what are your thoughts on those subs?
We have not seen a 708mk2 come through yet, however based on the amp and specs of similar RCF subs we have seen , the 708 will kill a KW181 and for the price point and features the 700w sub will be hard to beat from other "similar" competitors. We have found that QSC, JBL, EV and other fudge the power number to their favor to look good on paper, but poor on lasting performance. RCF has always IMO given the most bang for the buck.
trinityprosound would you say the 708 mk2 be more for small to medium size event halls or medium to large halls? Based on the size of the sub and specs compare to lets say a 8004 sub or 8003 mk2...??Thanks
yes, with the power of 700 watts RMS, but still has more power than a QSC KW181. The 708 as with the sub series is going to be similar construction and most likely at stamped frame basket like this one and maybe similar driver. Nice thing about SUB series is built in crossovers, you don't get that with QSC or others...with a pair of 708s the sound would be better than anything QSC or JBL or EV offers in that price range
trinityprosound would you say the 708 are for small to medium size event halls or medium to large indoor event halls?
small do medium, you will need double 18's for large indoor events and most likely more than 2
hi trinity, i have 1 sub rcf 705 as (first series). There is great difference with the 905 as II ? thks
yes, it has 200 more watts of RMS power and built in DSP. We installed 2 in a gym at at church as was really impressed with them.
trinityprosound thks. Do u think that with a pair of rcf 710 mk4 and ONE sub 905 as II is a good configuration for dance music with 100 max 200persons?
Actually i have 2 rcf 710 mk4 and 1 sub rcf 705 as.
Thks
Would be better with two of the 705's you are asking a single 15" to do a log of work.
what’s the best subs to pair with the rcf nx45a tops?
the newer SUB8003 would be great or the 8004, lots of power in either one of those
between the 8003 and 8004 what is better? what are the differences?
also how many people could i be able to run with that system?
better DSP on the 8003, newer design. are you a DJ or live band for that system... ?
iam a dj
Question would this sub be enough for a db igt4 one per side meaning one 705 with db igt4 per side
No. the IG4T will out run that sub, you will need at least a single 18 to keep up with it. KS10 or SUB18H or RCF 8004 or 8003 or FBT SUBLINE 118 will pair nicely with the IG4T's
Have you ever look at D.A.S. Audio?
Yes, but we don't need another line...and RCF and DB have everything and more than DAS
trinityprosound I just bought D.A.S. Audio Vantec systems they are pretty amazing speakers
I like RCF as well I have never tried DB though ran across your channel as I am looking to add RCF 705 AS ii and cant figure out what small 10 tops to pair with one sub trying to put together a small system without having to go with EVOX I had evox before as well it’s nice but want something different
I have not heard that series of DAS yet. Look at the SUB905AS more power and really a great sub with a lot of power. The ART boxes will pair nice with those subs, but I would look at the HD10. That box to me with new processing will do a great job with a 905
trinityprosound the 905 as ii looks to be a solid box
I am looking for something light that can be easily moved in a car from small gigs for 100-175 guest wedding dj type stuff easy in and out just with a little more lows than the EVOX 8 I think the EVOX 12 is over priced and not what I’m looking for so my thought was to get the RCF 705 as ii and pair up with 10” tops
What light weight good quality road warrior 10” would you match or maybe light weight 12”
I would to the ART series or the HD series, I like the look of the HD and they seem to have a bit more low end than the ART boxes. Everyone of my customers that have purchased the HD boxes love them.
Isn't it poor fitting a stamped basket ferrite driver to a sub costing so much?
Great point from 'The Boogie Knight'! Yes, I think it is very poor that RCF is fitting stamped baskets into some of their subs and some of their tops these days! In my opinion, the MK1 version was fantastic. It used a cast basket that was very durable indeed. I thought the idea of a MK2 product was to improve upon the previous design, however, in this instance, it seems they've gone backwards in quality, at least where the driver is concerned. I'm not sure about anyone else, but I'd rather pay a little bit more for better quality parts, rather than a company cheapening down at every revision. Come on RCF, don't wreck your brilliant reputation! Use only cast baskets, keep the weight down with NEO magnets and keep manufacturing in Italy, please!
Couldn't agree more. I would have bought a pair of these if they had proper cast, neo drivers. You can get subs far cheaper than this that are using quality drivers and it just seems RCF are relying on their name. Over here, the sub is around £1200 putting it in the premium small sub category yet without premium drivers. Just very poor.
@@theboogieknight8279 what do you prefer over the RCF in terms of build, sound and performance?
hi! this sub 905 as2 vs 8003 as2 ?
They are not the same. One is a 15" and the other is an 18" same amp and power. Me, I would take the 18" any day, moves more air and goes lower consistently
thanks!
We use the 905 and the 8003. Both mk2. The 8003 is as loud as 2 905 subs.
Go with the 8003. No regret.
trinityprosound eco 8003 as2 vs fbt cla 118 which is better?
Those models are very similar in power and output...we have the FBT dual 18's and they are great...but the RCF sub has a 4" VC on the 18" driver and i do like the amps of the RCF boxes a bit better... but both are good subs.
Hello. I have two RCF Art 745A's. And would like to get some subs for them.
Im currently looking into the following:
2 x RCF SUB 905-AS II
2 x RCF SUB 8003-AS II
1 x RCF SUB 8004-AS (And maybe get one more later, but im not sure this is worth it now with the 8003-AS II being out)
1 x JBLSRX828SB
2 x EV ETX 15sp
Can you give me a recommendation on which you would prefer and why? I really like the tight bass from 15" drivers. So i was thinking about going either with the 905's or 15sp's, but they only have a 3" voice coil compared to the 8003,8004 and 828 4" voice coil, so im sure its a good idea.
We can get the EV and JBL out of the equation as they are IMO pooh. The 905AS2 for a 15" sub is quite a beast and is tight and punchy. The 8003 for a single 18 is great, but my winner is the 8004, yes more $$$ than the others, but buy once cry once. You will not need to consider another single 18 sub again. Everyone that has purchased those subs "love" them and can believe the output from a single 18" unit.
Thank you so much for the reply. I will go with the 8004
How could you not like QSC?!.. I'm very happy with mine and they're still selling like crazy!
They are marginal and not much innovation. They sound just OK compared to others speakers at or near the same price point from RCF , db Tech or FBT. They lie about the power of the amps, or at least state it is 1000 watts , well yes peak it is... they have fans that can break and toast your speaker from overheating. They are only selling like crazy because stores like guitar center and others don't stock or sell much of the above mentioned and the margins they get on them, the poor buyers really don't get how they have been screwed .... the drivers in them are OK ,but OK is all I can give them...so many better speakers out there..
Nah..they can't be that bad, thousands of people can't be wrong. You tested out some KW tops a long time ago and seemed to be very impressed with the box. I'm by no means a one brand fan boy but my K12's and KW181'S two of each have done extremely well for me. I'm aware there's great speakers that will out preform QSC but the reliability of these is unmatched. Imo.
thousands of people don't know any better and take the crap Gtr. Center and others tell them is good. They have no clue that other speakers like these exit so they buy and have no clue whatsoever.
@@rudycorraudio9089 what I find funny is how he mentions kw181 with no crossover. Ok, fair enough but used with qsc you simply flip a switch on your top cab to with sub and problem solved. I have many different rigs for different events and while I like external crossovers, I know I always have a simple qsc option.
QSC is marginal audio equipment, power ratings are over stated and no true RMS power figures are EVER given. They use fans, which suck, if you don't have a top that has a HPF on it you are screwed. QSC uses marginal drivers and for what you get is over priced. I can get more out of a pair of Alto Series 3 boxes than K12 or K12.2 - RCF or DB Tech kills the QSC line -
I own 2 of these......after 3 gigs disappointed......., ive used RCF for most of my work over the years, one of the best all round cabs has to be the 312a i use several pairs and swear by them, but for the money, weight and size the 905 asii has lost my confidence, over rated, under powered, over priced....oh and far to heavy, should have used a neo magnet !, on the plus side the definition and tone of the bass is outstanding for the size of the box
that is interesting, because we just installed this one and another in a community room gym at a church and was blown away by the output of a 15" sub. We have used others including SUB15H from db tech and this one is WAY stronger, not sure how this 15 can be underpowered at 1100WRMS, most other 15" subs in this type of config are way less power, like 700-900WRMS if you are lucky. it is a bit more $$$ since it has great DSP and power vs. competition. physics pretty much dictate what you can get from a 15" dirver and the size and power of this box...we were impressed and will be using more of these on installs for sure as the small form factor fits nicely under stages...and yes is does sound amazing.
I just think maybe the 1100 watt figures might be little "ambitious" considering the early soft limit stage, RCF claim there is another 6db available after the soft limiter flashes, where would this extra 6db (which is quite an amount) come from ???.
it is the amp power, how it is configured in limiting or soft limiting does not effect rated or stated power, only how that transfers to the speaker/voice coil of the driver. it would be false advertising to be anything different that what is stated for the amplifier power output...would you not agree?
Am still in testing with mine, neo maybe 3.5” custom/3”
The RCF rep told me via email that after the soft limiter starts to flash there is still another 6 db left in reserve, now unless i missing something, if the signal is clean and the soft limiter starts to flash i just cant see where this magical extra 6 db is conjured from, if the soft limiter starts to flash and at that stage the level is increased or a piece of music is played with very low frequency then surely the soft limiter would only increase to protect the amp/driver....thus reducing power ?
do me a favor. could you make a review of RCF 9004 SUB AS?
it may be a while as we have not had one pass through our facility as of yet and have not rec'd a lot of requests for that single 18...but it will kill any other sub in the same class...the 8004 sub could put out more and sound better than 2 QSC KW181 subs...
