SPL & SQ / Fabrication

Time for a new box and im gonna need alittle help. Not really good at box design so thats where yall come in handy. I have two of the new 15" BTLs and i know the box from my x-cons are holding me back at this point. Im figuring i wanna go with 8-9cuft tuned to 34 or 35hz. Port area is whatever it needs to be for a good mix of daily and spl. Im assuming 100-125 for port area will do the trick. Needless to say if you can design me a box and the cut sheets id much appreciate it.

Lets just say I'm building a ported box. And the port is 6"x13" (Round port) How far away should the end of the port be from any wall? For example, the port is on the front wall. How far does the end inside the box need to be from the back wall? I think i remember it being 1/2 the diameter, but i could be wrong. If anyone could help shed some light on this one, it would be a great help.

So I've been reading a ton about aeroports and I've heard they reduce port noise and take up less space therefor reducing box size. I want to do two SA10's in 3 cubic feet tuned to 33 hz. I've been trying to use all sorts of different calculators and such trying to figure out port sizes and what not but its not coming together for me. Basically I want to know how you figure out port length and diameter as well as port displacement in the box. Also where is a good place to get these ports from. I'm going for a really nice sounding setup that can get loud if I wanna show off a tad . Any info I didn't include just ask and I'll do my best to fill in the gaps. Thanks BumpinAl…

Im looking for a box design for 2 15" Mtx 9500's for my 07 civic si 2dr,(H16xW40xD26 Roughly) Im looking for ported,trying to do subs facing inside the cabin with port the same. Any help will be much appreciated....... Mtx recommends 2.48 net enclosure per sub(from there website)(W 24xD 17xH 16)Port 2"x14.5. Now my trunk dimensions are 40w x 26d x 16h so i think i can make this work in my trunk...Right?just by taking 4" off the width and adding it to the depth and then make a 4" port........Can someone help me out with this....PLEASE??lol I listen to mostly rap and rock(for port tuning) Which of the following is the sub displacement?That would have to be minused off the…

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?

Pic 1 this is the front of the box that will be facing the front seats Pic 2 this is a view of the back/underside of the box. Pic 3 This is a back/side view of where the 4" diameter aeroports will go Pic 4 this is the other side The sub will be downfiring towards the back of the cab at an angle and im curious of how this will sound. im thinking that since the ports will be loading off of the door as well as the sub it should be a pretty loud design but i would like some opinions since im new to box building. i wasnt able to insert the actual image

Anyone know of any good Upstate NY Box builders, I was going to build my box myself but the Panel Saw that I was going to use is no longer available and I'm god awful with a circular saw. I'm in the Utica area to be specific willing to travel up to 1.5 hours for a good box, already have the designs courtesy of Alton. I'd also be open to out of state box builders but would have to be rather cheap due to the cost of shipping

So here's the deal. I have a Sundown 1200D, a Sundown 125.2 powering my setup. I will breeze over the 125.2 which will be hooked up to 2 sets of Polk db6501 components (2 ohm load) on each channel giving me a net of 100 watts to each speaker. I am building a CUSTOM box for a12" TC Sounds LMS-R sub. This sub can handle 1k watts continuos and 4k peak. I can wire this sub to be a 1 ohm load which is a load my 1200D can handle (giving out 1200 watts). I am trying to decide if I should port the box I am planning on building needs a port or not, and if so how long, size, ect I need it to be. I believe I correctly modeled the Treo TE sub I have now (in a ported probox) in t…

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?

website specs say they like 2.5-2.75ft^3 do they like larger than 2.75 or should i keep it there?

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 need help with a box design for a 15" Mach5Audio MAW sub. The recommended sealed box size for this sub is 62 litres (2.2 cu.ft.) 30hz tuning. I would like an enclosure designed exactly to these specs if possible. Thanks in advance!

Hey quick question: if im looking for say 33hz from an areo port in a box 3 cubes how do i calculate it if i need two ports? heres the situation, i have box 3 cubes, want to run 4 inch ports. if i make one port its 7.4 inches long but i need more area than that.

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.

Okay, so I have very little room to work with, and needed help on how to port a wedge box. I have 2 designs I can use for the port, both are using the same box. Width: 15 inches. Height 1 (front): 12.5 Inches Height 2 (back) 7 inches Depth: 18 inches total volume (using 3/4 inch think wood) = 1.06348 cubic feet. So one idea is to place the port under the sub which is the eaisiest. 13.5 inches long, half an inch tall, 14.5 inches of port space (32hz tuned) ^ I need to know if theres anything wrong with this idea? The 2nd idea, which is more complicated, is placing the port on the side of the box. I have no idea how to calculate such a slant. Would the 1st option be …

But I am no strager to working with glass and dont mind it if will yield the best results. Im going for SQ im over the bckseat box thing. My goal is a very responsive package that will hit a wide variety of HZ. with ought ruining the sub or the amp. Have not purchased the amp yet but I am looking at Rockford Fosgate Punch P325.1 mono The space we're working with is tight Do I attempt to make an enclosure that will fit the exixting cavity in the starage area or do we pull it out and go for somthing bigger?

I built this for a friend of mine. Its about 2.52 cuft per sub with 40 square inches of port per sub tuned to 36 Hz. The objective was to build a box that filled up the back of his truck. But that was too much air space overall, so we pretty much built a box inside of a box.. The pic of the inside looks pretty sick.

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…

ive been told that puttin carpet on the inside of a box will make the sub think the box is bigger there for sound better or louder. but i personaly like fiberglassing the inside to gurantee its super sealed and not falling apart ported or selad enclosure which would be the better idea or maybe carpet over fiberglass

I am in the process of upgrading my sub to one 10" Fi Bl are looking to have an enclosure built. Does anyone out there know of a good place to go in the Los Angeles, Orange County area to have a quality box built to mfg specs?

I am looking to build another box but want something unique yet efficent. I'll pay for the design. Some specs on the trunk: Cannot be over 14" tall x 20"wide x doesnt matter too much over 40" deep. The box will be for a 12" btl loaded off 2 aq2200s. I would prefer tuning no higher than 32hz. Lets see what someone can do.

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.

I'm considering building a bandpass box for my BTL, has anyone here ever heard a BTL in any of these boxes I listed below? If yes, how did it sound? I currently have a box built to BTL specs but tuned to 34hz.. Most people would be impressed by how it sounded and by how loud it got; but I would like it to get louder. 4th order: rear chamber sealed. front chamber ported.
