ok so i cant read a tape for nothing so i got the guy across the street to read it for me on my box iv'e asked this questions a few times but never had the right messurement's but now i do here they are the depth is 22'5/8 the lenght is 41'1/8 the width is 22'13/16 i have two L shape ports the messurement are length 4'3/4 depth is 18'1/4 and the bottom of the L sape port which gose toward the center of the box is 10'1/2 remember i have two L shape ports one on each side of the box with the same messurement's now at the bottom of the L shape port where it goes toward the center of the box i have 5'1/2 from the L SHAPE PORT to the back of the speaker box these are all …

ok so i want to make a box with 1 15 in the middle and 2 poorts, 1 on each side, to get it how i wanted it ported, could i just measure out the space i would need for 1 port and just put half of that on each side?

I was wondering if the calculator here ; http://www.psp-inc.com/tools.html calculated it's tuning including displacement of the tube or without displacement. Thanks.

First time building ported enclosure, I would have someone build it but I'd cost too much to ship and sounds like a fun project, sorry Argent hmm, scratch that the box volume is going to be 7.66cuft I used the port calculator at 12volt, port width: 30" port height: 2" port length: 13" tuning: 33hz I drew up this pic so that someone could tell me if "B" is part of the port length or what (p.s. picture is not in proportion to dimensions, just general.) So would A+B=13" or is A 13" and B is?

Ok guys ive been looking at some system setups and i found what im wanting to go with. Im looking at ordering 2 BL 10" subwoofers, well want im wanting to do is my truck currently has a bench sit and i was going to get to bucket seats and build a box/center console bewteen the seat and what i was wanting to know if the 10" will work in that spot and still have enough air space to beat down im trying not tunnel my truck because it is going to be bagged and not sure where im putting every where yet. I have a 90 Toyota Pickup Single Cab so if u can let me know that would be great. Here is a pic of a sample of want im waning to go with. The speakers in this truck are 8" spea…

Does anybody know where one us i want to see what i can hit?

Do crx boxes work in a trunk with the subs up an ports faceing the back?

This is what happens when you get wood cut at home depot. I got all my cuts at home depot and some are 1/16 to short. they wasnt using the regular saw. i was wondering can i use some sealer tape for the cracks?

Is each quantity for a 17" Long tube? What if it needs to be longer? 4" Port Tube

i have a fi bl 15 dual 2 with flatwind and cooling. it's going in a trailblazer; although i have a lot of room i dont want to use it all. i need some help deciding on the dimensions of my box and how i want it tuned. I want it to sound good but get really loud. i listen to all kinds of music if that matters. any help would be appreciated.

Just need a little help with my box. Running 2 15" Lanzars http://www.lanzar.com/itempage.asp?MODEL=MAXP154D This is the box I've drawn up. Driving a 2004 Ford Taurus. Not very good with boxes. Can anyone come up with a better design?.. Max dimensions 36L x 18H x 20W I'm not sure about "tuning" to certain hz but I would like to hit LOWWW bass please Current Design:

Ok, so this weekend I plan on pulling out my box and putting the zcon's in. 2 12" 1 ohm z's goin in. Gettin the diehard platinum marine sat nite and puttin the saz2500 in. Rt now my box is 4.75^3. Its an angled box to fit behind the seats of my 3 door s-10. I have another 4" of room I can go up. That would be about another 1.4 cubic feet or so. Rt now the port is on the side and has about 78 inches of area. 19.5 wide by 4 tall. Is that enough or should I make it bigger while I have it out? Or should I leave it alone? Also what would be a good gauge of wire to run for the subs? I cannot wait to hear these z's rumble!!!!¡¡¡¡¡

I want my subs to face up with the port up like one of my previous boxes. I cant seem to get a lot of input and like Ive said previously the pro designers dotn wanna mess with a camaro enclosure. Assuming ive done my math correctly does this look like a suitable enclosure? I just started using sketchup so I have figured everything out so nothings 45'ed or anything.

I've spent a couple hours sketching up various designs on re calc and torres box calc. However, all I hear about any of the box design apps out there is that they are total crap. Working as much as I do these days I simply don't have time to become an expert in this area. Also understanding that install is a huge factor, I don't want to screw the design up. I am looking to build something this Saturday and want to get it done right so I don't have to change it again because of an improper design. I know there are a bunch of you out there that can do this stuff in your sleep. I don't mind paying for a solid design with cut sheet, etc. (i have PayPal) I also don't need anyt…

hey guys I'm about to start on my new box for the TI and was wanting to put some internal bracing for this box. Does anyone have some good pics of internal bracing, I need some ideas on what to do here. I already have the box plans, just need to get some basic ideas as to where to place the bracing. thx. -chev

Alright so iv made my box and everything and I would love to use body filler to smooth t all out and cover allscrew holes. I don't really want to spend any more money for this box... What's the cheapest way to obtain the perfect box?

I attempted to download the IASCA rules today from IASCA's website (that looks and works like it was created by an 8 year old) and they require an account for download. For what reason, I have no idea. They also locked the PDF's so you can't print them. Anyway, I got the files another way and uploaded them to FloridaSPL.com/iasca (no account needed)

I talked to Nick at Incriminator Audio (Subwoofer Maker) I believe, he said go with 2.5 Cubic Ft per sub and a 70 inchs port in a 6 Cubic ft Box. 2x Incriminator Audio Lethal Injection 12 Inch Subwoofers. I did some further refinements. This is what I came up with Subwoofer Volume - 2.5 Cubic Ft Port Hz - 32 Box Specs: Width - 36" Depth - 26" Height - 14" Net Volume - 6.36 Gross Volume - 5.08 Cubic Ft Volume Per Woofer - 2.54 Cubic Ft Volume Displacement: 0.22 Cubic ft - Woofers .056 Cubic ft - Bracing 4x 45 Degree Corner Braces 1 Cubic ft - Port Volume Port Specs: Port Volume - 1 Cubic ft Port Area - 91.05" Squared Port Diameter - 10.77" Port Width 2" Port Height 12.5" P…

I have a Soundstream Reference 500sx rated at 500 watts in 1ohm & 2ohm, is there a difference in sound quality in the different load and what about subs, does it make a difference in sound quality if you have a dual 1ohm or a dual 4ohm sub wired at 2ohm load are there any differences in sound quality.

I am getting two Maw-15's and I was wanting to put them in a Ported Enclosure tuned to 30hz. But I drive a 1996 Ford Taurus and I'm worried I will come up a little short on Trunk Space. Any Ideas for the box Or do those subs sound good enough in a Sealed Enclosure? Thanks In Advance Guys. ~MadroX

Hi guys, I 'm always trying to improve my system. I have a 15" xcon and a 1500 watts Sundown saz amp. The car is a hatchback toyota Auris, with a little trunk. I had a slot ported box with sub up and port up, at 3.5 ft3 at 32 Hz. This box was too big for the trunk, but I thought it was not the right one for my car. I've heared this same box in a smaller car, with the same setup, and it was ...insane. In my car, it was not really loud. I have, now, a 3ft3 sealed box, with the sub firing back ; I found it was better than firing up. So, here is my question : if I want to do another ported box, what would be the best choice ? Sub and port firing back, or sub up and port back …

((2 * 250.3125 * 10) - (0.159230769 * 2 * (12^3)) - (30.830229 * 2)) / (12^3) = 2.54299074 cu ft. That’s with port, sub, 45s and skeletal displacement taken into consideration. That makes the box tuned to around 34.02Hz if the math is correct..... let me know guys, what you think it is for 2 dc audio xl 10"s powered by an aq3500d1 in a 1ohm load, think my tunining is to high? still able to hit the lows you think? i wanted to be able to play normal music as well since its my daily driver 1st real build so im just taking everything into condsideration since this box is built already just waitin on my other d3100 to come monday

Subs: two DC Audio LVL4XL 15's Here is the room I have set aside for the box. I can possibly go bigger. But, if possible, would like to not go bigger. 23 inches high 20 inches deep 38 inches wide I want subs up and the port up. I would like to use a slot port. Tunning could be at whatever would work best with the dimensions given. Anywhere between 30hz to 40hz would be fine with me. I dont know what my cabin peaks at but I have had two setups, one 18 tuned to 32 and two tens, not sure on tunning, Both setups peaked at between 40 to 45 hz. I will be using a US Amps AX3200DE to power them. This will be in a small SUV, 07' Honda CR-V.

I was messin around and just seein where the power wire would go through, and i realized that the firewall already in use for the factory wires was pretty much full, and i don't see how 1/0 is going to squeeze in there. But a couple inches to the right and one or two inches above it, theres what i'm guessing is an unused firewall hole. Its a rubber surround with a rubber filling. I tried to see where it came out on the engine side, and i couldn't find it. Does anyone know if i could (once i find the hole, as it was a little dark when i did this) puncture the rubber filling and take it through there? If not, what should i do?

Hi all Just wondering if someone could help me design a 4th order bandpass box for my AA chaos 12" ive decided i want this for two reasons. 1 i own a sedan with a sealed off boot and this is meant to be one of the best boxes for this application. secondly these subs are meant to be awesome in 4th order. i plan to port the box through the speaker holes in the parcel tray. ohh the car is a toyota jzx100. ohh i also plan to use this as my daily box. thanks heaps.
