if someone have 2 subs 8003 as ii & 2 subs 8004 as , one 8003 and one 8004 per side could setup these different models ? the sound result is ok or you can not use them together? (for live performance situation) sorry for my bad english
Hi Chris, it would be best to have matching cabinets to help with phasing and cone filtering. We have had people do it before to add to what they have. It wouldn't sound bad as long as the boxes were lined up with the 18" subs in the same plane with each other and the crossover settings were the same.
How do 2 of these push compared to one SUB9006? I need some extra subs and I really don't know what to do. Another 4 of these 8003subs or 2 SUB9006... What do you think? Does one 9006 push harder as 2 of those subs?
I couldn't see any phase swtich, button or menu on the new 8003 ASII why RCF company didn't put a phase swicth on it. I'm wondering that, is cardioid presets acts like phase button in any case ?
Hey can i use a compressor limiter on it? And other audio processor components like dbx 3 way crossover? Thank you for answering my question at your beloved page.
Mr Jn you can use an external processor on it for extra protection. The only thing you couldn't do is go beyond the preset crossover settings. Example if you wanted to crossover at 140hz for the sub the subs internal crossover would only let it go up to 125 if you had it in the L4 H4 or C4 settings.
Sweet Tree Productions so the things i can do is just set the crossover frequency in 120 hz also. Thank you so much for replying at least if i do it i know it will create a beautiful sounds.
Nice review. I'm curious about how is new RCF 8003 ASII ' s SPL output and frequency response compared to the 8004 AS. I have 4 pieces of Behringer B1800HP which is very heavy for single 18" but nice sub for the money. If there are any chance i want see a comparison video before i change my subwoofer equipment. Please can you ask someone or make a comparison between New 8003-ASII , 8004 AS, and Behringer B1800HP and write to me. Thank you.
The 8004 would definitely have more horsepower than the 8003 we have installed many in Churches they are very impressive. If you are in the US give us a call at 2562754734 and we will get you the best deal possible.
I'm living in Turkey and DJ'ing at big wedding events. Also I'm renting sound systems to small to medium size bands. Now I have Behringer B1800HP subs I'm happy with their output but very heavy cabinets. I dont know new 8003-AS-MK2 equal or can beat them can help me about this issue. If there is a big difference between this two models may be I can change my mind.
This is the best 18'' sub on the market. At this price point you can not buy something with a better construction or more power. This sub outruns the kw181, jbl prx 618/718, mackie hd1801 and ev etx18sp.The funny part is that the next level subs comes again, from rcf. I mean sub8004as.
I am Dobix I've tried different settings on the new 803 even the H2 and H3, 12 and 14 gauge cables and still limits very early. I asked RCF for support and they advised to keep pushing them until solid red. I'm ok with doing that but I've never had to push my other subs past limit for them to keep up with my tops. In this case ev ekx 15p only 1,000 watts.
Hello. You can push them with no worries. They made those new amplifiers a bit different. The red light is not the limit. It is just a "pre-limit" warning.Only when the light is constantly red, then its time to turn it a bit down.
Another tip: Those subs are meant to be used in pairs. 905, 8003, 8004, 9006, 9007. All the subwoofers from the SUB LINE, they punch really hard but when put in a pair. At least 2 of them.
I am Dobix That's the exact answer I got from rcf.. dosent make too much sense to me Especially because they start to limit when my tops are only at 50% volume.. but they do sound nice at low volumes just not what I was expecting from a $2000 speaker. Thanks
I really don't know what could be the problem there. Mine work just fine. I'm using tt25a ii tops and i have a nice boomy sound. I still need 2 more subs but that's just for bigger gigs with 1000+ people. It really depends on what "loud" means to you.
Hello! Can you tell me what you recommend between rcf 708 and 8003? Paired with 715. Got the 708 but it blinks way too fast. 8003 will be a better choice or should I get another 708?
hello I have the new 745mk4, and I bought a 8003mk2, can you tell me the correct settings of the sub? and also the volume that holds both the 745 and the sub?
Did you like this combo i also want to buy the 745 and the 8003 but im not sure if i need two subs :/ but i have to listen it befor ill order it 😂😅 wich music do you play?
@@sweettreeproductions2149 how's the 8004 compare to 8005? Love low's but still preffer chest thump, 21' should give more thump, or in this case just more vibrate feel? Allso will be good match for hdm45a?
Can someone explain the different settings of this sub please, I just got a pair with the rcfs art735 and have no clue how to set the subs to the best spec to match the tops! Thanks in advance
DJ GUERO depending on what type of music you will be using these for there are a few options. For the 735’s we would recommend the L2 setting and then use the crossover output to go to the top for most situations. This will allow the sub to do most of the hard low frequency work and the top to still produce some down to 80hz. The H settings don’t go down as low so they will be good for rock and country. The C settings are for Cardioid set ups which would involve at least 3 subs per side with one inverted. This mainly reverses the phase of the Speaker while also changing the crossover frequencies. Look at 2:18 for the Key.
Sweet Tree Productions awesome! Thanks for the reply!! One last question I noticed that when I do use the L2 setting the subs sound amazing but I want a little more juice out of the tops, is it bad to change the tops input setting to mic and lower the gain to about 3 lines of volume? When I do that I get an awesome punch from the subs and great clean audio from the 735! I just don’t know if having the 735 in mic mode to produce my music out of my mixer to hurt anything! The 735 never Clíp and they still sound amazing! Thanks
DJ GUERO it is usually not a good idea to put them in mix mode unless you have a microphone plugged directly in to them. We would recommend turning the gain down on the sub which is the first menu function and then turning the tops up as needed in line mode. We usually run all of our gains on our tops at 3 o’ clock or 75% appears to be near unity but 100% wouldn’t hurt either as long as you sent clipping. The only problem with mic mode is with the gain that hot you can introduce a lot of noise from your mixer that way.
Sweet Tree Productions well I was amazed at the system once I set it up like I’m telling you and got no noise from the mixer, other than that will it cause any damage to the speaker? I’m more worried about that, I mean the gain on the 735 is really low and I get 0 clipping, just want to make sure since I really don’t know sorry. Also the first menu is at 0 and then goes up so you lower the volume on the subs by going up in numbers instead of down?
Ive have been using 2x 745 and 2x 8003 for over 5 years now. The 745 are too powerful for this sub. It sounds great, but i wish i would have spent the extra money and gone for the 8004s.
Hola me podrías ayudar tengo 2 8003 RCF y tengo 2 altavoces 715 y otro 2 altavoces 732 Utilizo este sub para música en vivo ya que lo utilizo por que soy dj., me podrías ayudar nose que CONFIGURACIÓN ponerle me pica en rojo muy rápido y sin aún está al 80% del volumen
Por lo que aquí se ha explicado en inglés, los amplis de estos Subs RCafa los han hecho diferentes, y que estén parpadeando en rojo no significa que esté llegando al límite. Aquí han explicado que hasta la misma marca dice que hasta que no esté en rojo constantemente no hay problema. Solo cuando se quede en rojo, como con cualquier otro equipo, es cuando hay que tener cuidado.
@@mervynaujayeb As I said, blinking is okay, just when it blinks more than 1 times per second then you have to turn it down. If it's not loud enough for you then you have to buy more subs. Sub placement is very important
What would be the best preset using non rcf tops for example EV elx speakers.. thanks...
Good job
Thank you!
Awesome
What is your gain on the 8003. 0 or 99?
if someone have 2 subs 8003 as ii & 2 subs 8004 as , one 8003 and one 8004 per side could setup these different models ?

If you don't need the RDNet capability of the 9006 we have been extremely happy with our 8006 subs.

Would you rather get the 8003 or couple a pair of 708 as ii's? Just curious.
Honestly? Couple pair of the 708’s we just aren’t crazy about the new model 8003.

The RCF cabinet would have much more output and gimmick dealer than the Behringer. Best of all the weight would be less as well.
Thank you for this information. It will be a guide for music bands and many dj's who is thinking to buy new equipment.
Necil Aydin no problem. You can't got wrong with RCF!
Is rcf 4pro 8003 as good as rcf 8003-AS II? or there's a big difference between the two
We like the original 8003 better.

Great review! Is there a
notorious difference between subs 8003asII and 8004 ?
We really think there is a significant difference in tone and output. The 8004 is a killer single 18.

@@sweettreeproductions2149 the 8004 is Killer but Heavy af. Are 2 8003 nearly as powerful as 1 8004?
the 21 inch sub will give you that lower bass enhancement while for the thump you’ll need a smaller sub or the top speakers running full-range
What is optimal setting when using with NXL24A?
We like to let the subs go close to 120 for the 24’s.
hi, on the old 8003 do you no where 0db is, would it be full on or half way?
full way

How do these compare against the 8004s? The weight of the 8004s is the only negative I see..... do these even come close to 8004s?
I have two of the Rcf Art 945 tops. The 8004 sub is too heavy for me. Can I get by with using two 8003s?
The sound of the 8004 will be much different the 8003. The 945’s are great tops.
Hey, did you get the 8003s? I am also considering 945s with the 8003
How this comper with the ks181

@@sweettreeproductions2149, thanks! but I'm in Spain. Too far, sorry!
Do these speakers limit early? How would they compare to the kw181
djosvani they are producing a lot of bass before they limit. In our opinion these beat the KW181 which also is a great speaker that we sell.
Can you tell me which are the best sub for RCF HD 32, I have two HD 32 boxes?
We would recommend the 8004, but if budget doesn't allow we use the 8003 with them a lot as well.
Ive have been using 2x 745 and 2x 8003 for over 5 years now. The 745 are too powerful for this sub. It sounds great, but i wish i would have spent the extra money and gone for the 8004s.
Same here
I think two 8004’s are still too light for the 745’s. You will need at least 4 to outrun those
We agree the 8004’s are the way to go.
I think they hit limit very quick I have found with mine
Try using the presets that do not go under 40hz. Those are the h1 h2 h3 and h4. H3 works the best for me.
A ok I do use the L2 L3 with Trim set to 40 but it still hits limit quick
I will try the H3 so
