MEASURING downfiring ported TW3 build! How does it sound?
Вставка
- Опубліковано 10 тра 2020
- A downfiring ported subwoofer enclosure can free up space for cargo since you can set things on top of the box, and also have great low end output due to being ported. How did the JL Audio TW3 perform in the box that I just finished building? Let's do a listening test and measure the performance!

LOVE that your using REW! I discovered them several years ago when I started tuning large Pro Audio systems I was installing (think community centers, venues, and contemporary houses of worship). Thanks for doing this series. This is the sub I plan to put into my 2008 G37s some time next year (hopefully).
As for the amp/gear beauty panel... Of Course we want to see that!!
Just ordered my encloser plans from you Mark. Can't wait to get building!!! Love the video's. They got me back into fabrication
As always you do the best installation and the result it's great!
Thatll be great if you show adding the fans
hell yeah I wanna see the fan installation! Gettin more techy is always interesting. I think this is a subject not often covered in good detail. When it's a good idea to use a fan, when it's overkill... what type of fans, how to setup relay with it, push and pull fans. How to build a glorified computer case inside a car cavity :D
I'd love to see you fab something up for those fans!! I'm actually planning on doing something similar.
The fan build will be much appreciated- like all your videos. Thanks!
I have a 10TW3 in a custom ported box under my back seat. I'm very impressed with it
I just installed three TW3 10's in a ported box and went over the box design with Eric Cole. I have it powered by an JL RD 1500/1 wired at 2.7 ohms and it gets down yet really accurate. The ported box is still smaller than a lot of dual 12'' boxes. I really like these subs
How does it sound
@@BIG_FETUS really good. just triple the internal depth and port width of Jl's ported box design for a single sub and keep the other dimensions they provide add some braces going front to back between each sub. Its not an spl machine but can be heard a long way and is also SQ at the same time.
Hello. Thank you a lot for you installation tutorials; I have almost watched all of them, but I want to build a sound system and there are some concerns that I don't hnow how to deal with.
I have Hyunday Elantra 2020 and I want to install 1 woffer, 1 midrange, and 1 tweeter in the driver and passenger sides. I also want to install 1 wofeer and tweeter in the back doors, and subwoofer in the trunk. I want to use the factory audio unit with DSP and amplifier.
The question is how to wire all of those speakers, specially that most of the amplifiers and DSPs come with 4 channels, but I have around 11 speakers? I have a problem imagining the wiring, so please tell me how to wire this system briefly.
Thank you a lot
Awesome job, beautiful build!
I wish they had these type of grill for my 12w7. They only make the three bars type.
Great to see REW being used in the Car Audio world!
I have a technical question I hope to get some help with. I've set up my system and at my power to ground leads I get 12+ volts, when I turn the ignition to the accessory or turn on the car I'm only getting 8 volts. I can't figure out why. the amps won't even power on. Thanks!
Very Useful, Mark! Thanks a lot!
Hi, I'd like to add 2 x 12" subs into a Grand Caravan - would placing these in a downfiring box in the rear work okay, or would this come at the cost of bass?
I'm planning to use a sealed box, as I prefer sound quality over tooth shattering bass
Definitely do a video on the fans, I plan on using fans and it would help me and many others greatly!
Love my 10 tw3s they thump and sound great
That sounds pretty damn good for shallow mount 10" goes to show how important a proper box is.
Absolutely on the fans. I did some work with tiny fans to cool an offroad compressor. I'd love to see your method and tips.
How much from the ground does the sub have to be to sound it's best? Seems to me that your sub has enough room but it can benefit from a little more room.
yes, please show your fan installation. I plan on doing something very similar in my 95 Land Cruiser fj80
Hello, can you advise me for the manufacture of the case of my 30 diameter sub?
Odd question, but do you know approximately how much the box weighs? I'm considering it for a pro-touring car that sees regular track days and autocross... weight is always a factor. Thanks
Did you do any measuring on the other down firing box with the dual firing 10 inch subs?
Yes please show the fan installation. What brand and size of fan is that? Are you going to use a tm-1 to control them?
Do you happen to have the difference in spl numbers for dads Equinox vs. factory? I know neither are for db's, but I would love to know the decibel gain over stock or their Pioneer that sounds nearly identical to see if it's worth upgrading to the JL formed enclosure or should I just slap a box and amp in the back? Really would like to see numbers and changes in frequency with the bass.
Yes please to seeing the fan mounts!
Hi! I would like to ask you if you see fit to use that sub with passive radiators in a car enviroment instead of ported? I have one of those in a sealed box that was made to substitute the rear top panel in a 2013 Hyundai Accent hatchback, because I wanted to have the cargo space available. My intention is to get more extension to lower frequencies without going into port noice or chuffing. What is your take on that? Thanks
Definitely would like to see you adding fans! I was questioning whether or not I should do this with my amps recessed into a faux-floor.
It is very good my friend!!👌
I was wondering if you have any reference videos explaining how to build a 6th order box. I am wanting to build a 6th order console box for my pickup. I plan on using a sundown zv5 15 d1. It will be my first attempt at a 6th order build. Any help you could offer would be greatly appreciated.
Hi Mark, what would be the ideal amplifier for a jl 10W7 v.3 in your opinion? Thank you
How do you think this sub compares to a jl 10w1v3-4 in a downfiring sub box?
You know we want to enjoy that fan rack build :)
I have the same sub and need to build a box for my 95 c1500 standard cab . Any suggestions?
hey guys. i was wondering if i can take signal from my radio send it to a crossover then from the crossover to a eq then to an amp
Add the fans! I was actually thinking of doing the same with where my stock sub “box” is. The build is gone be juicy my guy. 👌🏻
I want to see the build for the Amp rack panel FOR SURE! In the 90's I used to use push pull fans's across neon lit, plexi covered amp racks. With the cool air coming in from the car, and heated air exiting the car. I'd love to see how you tackle that, as I am building a similar system where my amps and DSP are behind the Vehicles Interior panels. Rather than in an MDF made rack. Thanks Rob / Winnipeg Man. Canada.
Great job Mark. Just thought since the speaker is installed from the bottom you would use clamps to hold the retaining screws instead of screwing them directly into the wood. In one of your videos you advised not to screw directly to wood because with vibrations they may come loose and will not "grip" into wood as tight again. Overall, you are an excellent source of know in this field.
Yes I want to see how you build the fans. Eventually I’m gonna hide amps and would like to learn that
What crossover point did you end up using?
Hey bud! Nice video! I work at the warehouse were those speakers are build!
I could have posted this question in a different video but let's try it here. You have made videos before where you use the cars own head unit and add aftermarket amplifier and that is "simple" but how do you go forward if the car already has a amplifier with factory installed sub and you want to keep that amp with original speakers but replace the sub and add amp to that to get that deep bass that the stock subwoofer just can't produce? I have a Ford Fiesta ST MK8 that has B&O speakers on it with 500w amplifier split between subwoofer and speakers. I would like to replace the factory sub and add amplifier to the new sub but still keep on driving the speakers with the factory 500w amp. Can I get the signal from the factory amp to subwoofer amp with DSP or something like that?
Chosing a small redux fan is an interesting choice. They have higher static pressure than the larger fans but given the application in unsure if that's needed. Wouldn't it make more since to go with some 120/140/200mm fans since they will be quieter or what noise they do make being a lower pitch and making it easier to ignore. Ive had my hands on noctua 200 mm fans and they are suuper quiet. Granted ive used noctua 60mm fans and some 3d printed ducts to keep the space behind my headunit cool on my silverado when I head a processor crammed back there
Can you make something like that but instead of a port, use a passive radiator?Then compare it to this.
I would love to see how you integrate the fans into that subwoofer cover panel.
I need this style box in my life!!!!
The sub’s response from that sub on my full Kappa components sure sounded fantastic for a slim sub 😁 can’t wait to build a fake 4 cu/ft wall into my RL for a Dayton Ultimax 12”
How does this sound sealed using 13.5 tw5 v2-4 slim subwoofer?
What do you think about 4 13tw5s in a 4th order?
I have a wiring question for anyone to answer...I have a boss audio ar1200.2 amp...it says its 2 ohm stable per channel, 4 ohm stable bridged. I just bought a planet audio tc10d 1500 watt max dvc 4 ohm. I want to wire it down to 2 ohms. So since the amp isn't 2 ohm stable bridged is it possible to wire it down to 2 ohm and then run the positive and negative from each voice coil to each channel on the amplifier?
Can you help me with box plans for 2 12in jl tw3-d4 subs???
a video of the panel build would be great! I use Noctua fans in the majority of my customer pc builds
Hey Mark, any idea why JL audio doesn’t recommend the sub to be in a ported enclosure maybe because they flex too much? I don’t know. Any suggestions helps, I am thinking to install two of them down firing in a Ford F150 but not sure if the right move is a ported or sealed box thank you.
I would like to make a subwoofer speaker for a 30-diameter component and I have a 15-diameter horn tube, would you be courteous to do the calculation to make me the dedicated speaker? then I'll pay you for the trouble in the canal.
*sees the fan.* *excitement* NOCTUA! My favorite fan brand!
I have 4 2 ohm 6x9’s and a 1 ohm stable 4 channel amp. How do I wire this set up for 1 ohm?
It's not possible to wire that to 1 ohm/channel. If you want to do the calculations, look up resistances in both series and parallel arrangements.
What hz was the box tuned to?
Any ideas on how I can get my sub to imagine closer to the front. I can easily locate it when playing my system. It’s a 10 w3 in a potted box. Crossover at 80 hertz and 6.5” Jl Audio c2 components are also crossed over at 80.
Edit: I do not have any DSP just headunit and amp.
You need a DSP, time alignment and making sure the subwoofer is in phase with the midbass speakers is key, that and treating the doors for optimal mid bass.
Try shifting your crossover point down to 55 or 60hz. (If the door speakers can play that low safely) Lower frequencies (30-50) are harder to localize, so if that's all the sub is playing, it will be harder to tell where it's coming from.
Replacing the interior in my 1984 Suburban. So while I am doing this I am upgrading the very lacking audio. The original speakers are two 3.5in in the dash and 2 4x10 in the rear....and that's it. I am not doing anything crazy, but hear is my plan. Replace the two 3.5in in the dash with two 5.25 coaxial speakers in the front doors, two 6x9 coaxial speakers in the rear, new head unit, speakers all powered by a 4 channel amp. I'd also like to add a single 10in down firing sub powered by it own amp. I am building a custom front center console between the 2 new front bucket seats and thought it might be nice to build it in the center console using this design. Question is...do you think it would be too far forward in the suburban to place the down firing sub in the front center console?
Right after you say let's have a listen UA-cam played me the oral B commercial. Was confused for a sec there. 😋
What is the port tunning frequency plz tell me
Yes please show the fan build
Please do the fan install video
Do you do personal builds for customers?
Mark I have a D6.1200 and was thinking about going toslink in, if I'm bridging front channels(1 n 2) (3 n 4) will I still be able to pull left and right signals separate
That amp doesn't have Toslink
Not sure why I thought it did, thanks for the answer and great content
Honestly bro! You don't have to ask, of course I want to see how you alter the factory panel to integrate fans and maybe a lil Plexi and LEDs to show off the amps. Keep up the good work my guy
Got it!
Hey Mark, I made myself a sealed box for my P2D4. First ever sub enclosure, so yeah I F'ed up and over built it so the size is about 31,5 liters, planned size: 16,4 liters. Any tips?
Thanks for all the inspiration!
You can reduce the size by adding wood inside the enclosure. Or of course rebuild, always good practice!
@@CarAudioFabrication problem is that it is a glass fiber box. But I'll give it a shot to close off some of the box👍
Would industrial velcro worck?, the thing is that i build a down firing box for 2 Rockford p2d2-8 for a highlander 05 with third row seats. I desing it so it can still fit it behind the small area left in the cargo area when you use the third row seat so i want it to have the benefit of reorienting the box. Btw i made the down firing sub box's feet 1.75 " wide for the porpuse of using velcro.
Also thanks to C.A.F.!! because of you I've been able to learn and start making my first car audio build.
Slick as usual.......how many hours are in the box build?
Hey Mark, is it ok to mount amplifiers upside down?
And YES please show the process of mounting the fans.
Another great video. Thumbs up.
Could you build wire and do every step but not use all the eq tech, or if that is a necessary step how would a beginner do that any free software anyone knows of? Just reaching out looking for help from anyone.
Awesome!!!!
Thank you! Cheers!
I have two TW3 12s would a ported box fit or work in my 2011 Chevy Silverado
I run 2 10s tw3 non ported in my crew cab. They sound very good and fit well. Ported box will be much bigger.
Are those Noctua fans?
Amazing talent and skills you have buddy
You are louis Vitton of subwoofer looks top class not easy to do it for diy hobby guys
Hello Mark. Is the a way to contact you for advise?
does downfire feel like the bass hits harder?
You are clearly the best in America on UA-cam for car audio! The only other channel I watch for car audio is from the UK. That guy is the shit, too!
Yes let’s see the panel made
Would you build bandpass sub next?
How much air space is that enclosure?
I need help , how can I get in touch with you
I would like to do something like that with 2x 10s down firing taking up the trunk area
Yeah, let's see the fan fans!!
Would love to see a front passenger footwell down firing subwoofer build. 🤙🏻
why not integrate a large fan in place of the grid and keep it as a pretection with a filter according to the suction or extraction direction
Hello can I order a custom box for two TW5 jl audio for a 2020 Silverado 1500 , I want the box to fit behind the seats, Not under the seats.
Let me know if you found one
Awesome to see which works best.......blowing cold air in or removing hot air.......or both🤔🤔🤔
i have some questions I would love to get some expert help with please ok I have a class AB 3200 watt max amplifier RMS 1600 watt @ 2ohms I also Have 2 12″ 400 watt RMS 4ohm subs wired for a 2ohm load which adds up to 800RMS watts that's half of what the amplifier can produce should I be able to use the amplifier with those subs or is it too powerful? If not can I make up the difference by upgrading my 6.5″ speakers to some coaxial speakers with enough wattage to make up the difference and should they be 2ohm or would 4 ohm be ok for the 6.5″ my guess based on all I've learned is to stay with 2ohm on the whole package but I'd like an educated opinion because basically all I've learned is from watching alot if you tube videos and reading half ass tutorials that more often than not leave me with more questions than answers I am a noob but I am not stupid and I pay attention to the lessons I am taught I'm currently working on my second car sound system my first was a hard learned crash course into car audio because it was on my 2006 Mercedes E350 W211 with factory Harman Kardon fiber optic amplified system so you can imagine how much I've had to learn in a relatively short time the system I'm currently working on my 2009 Acura TSX and I am retaining my factory stereo and using a line output converter to do so anyways sorry for the long story but I wanted to give as much detail into my project as possible to help get as detailed of an answer I can possibly get if you feel up to it please give as much detail and information as you can I will retain any knowledge given and it will help in future builds thank you .
Whether or not those subs can handle the power available depends on how crazy you get with the volume knob, how the amp gain is set, what enclosure they're in, and what brand the subs are. Some companies have subs that can easily handle double their RMS rating, while others will fry. Just depends on the company.
How many cubic feet is this, I have 2 JL12TW3s in my work truck and I’m trying to put them in the trunk of my girlfriends charger. I’m only finding pre fab boxes that are 4 cubic feet ported. The manufacturer suggests .95 for a ported box..... Please Help!!! 😭
jl audio. kings of foam surrounds and $30 grilles.
you should do a single 12" or 15" spl build. and meter it.
I hear they are also blockers, but YYZ by Rush is a great test song for a system. Staging, percussion, etc.
Want to see the fan mounting!
Show the fan set up
Do it bump doe?
We wanna see how u add the fans
Can you build and sell one?
