I was wondering if anyone new of any good enclosure design programs, the only one i know of is term pro. I was just wondering if there were any out there that were better. I am trying to do some experement ing with some bandpass enclosures.

Today's massive frames and motors add challenges to designing enclosures these days. What is the general "rule of thumb" for the minimum acceptable distance from the back of the woofer's motor/pole piece vent hole and the back wall of the enclosure, or a port wall? I'm playing around with different designs for an older Rockford Fosgate T210D4. I can handle the designs myself, I just need some input in this area. Thanks in advance!

Hello all, I'm new to this forum, but not to car audio. I am however new to the Sundown woofers. I'm hoping you all can lend some help and thank you in advance on my enclosure design. What I have is an 05 Acura TL I'm doin a pair of Sundown SA12s in the trunk. Subs to be fired foward and a 6in Aero either out the back or side. I have tried several enclosures with foward fired subs & port, but the car just did not really like it. Last setup was a single CV Stroker12, power was supplied by an O.S. USamps VLX400 1ohm mono. I had good results with two 4in PVC ports fired back, Sub obviously foward. Then tried a 6in Aero out the drivers side of box. The Aero was slightly b…

Looking for someone to help me design an enclosure with a kerfed port. I have been trying out doing it on scrap wood in my garage for a while and wanting to try it out on one of my enclosures. I have someone wanting an enclosure built right now and figured it would be a good one to start with. Its for 2 sundown sa8v2's in a trunk . I was told there Going to be on 1-1500 rms. . .Max dimensions - 30 wide 10 tall and 16 deep. (Ill ask if any of the dimensions can get bigger) Wanting it subs facing up and port back. Tuned in the low 30s. 30-34. . . . . Listens to mostly rap music.

ok so i really dont trust most of the box calcs. online so i've been researching formulas and anything i need to know about designing on my own. so anyone with advice please put in your two cents..... tell me if i got this much figured out: 1). to come up with the ft^3 of the box you multiply length x width x height using the inner dimensions. then take the total of that and divide by 1728 which is the in^3 of 1 cubic ft. 2). then to factor in port, bracing, and driver displacement you use the L x W x H on each item and subtract it from the ft^3 3). for box's with a slanted front. for example the top is 5" and the bottom is 15" you find the average of them by adding them…

I currently have 4 cube after all displacement with 43.75 sq/in of port fireimg down the middle tune @35hz. I was told that offsetting a port to any Side would raise enclosure efficiecy And get louder.how true is this? my new plan is 3.8 cube with 50sq/in of port tune @32hz with the port off set. sub are fi btl12 n2 with the mmats hd4000.05 and dc xp 270 alt x3100 in the rear xs2700 up front in a 03 impreza sealed off from the trunck.

I am planning a fairly large system as my next project. I'm curious to know what you guys think of oddly shaped enclosures. I'm not talking about the plain jane square boxes, I'm talking about enclosures constructed out of nearly 100% composite materials. You know the ones made to fit oddly shaped areas such as the sides of trunks or in spare tire wells. I am planning on 2 Fi.BTL15's and in order to get them in and still have room for amps I am going to need to use fibreglass for a very large portion of the box to maximize the enclosure size as well as the usable trunk space for amps and such. I am under the impression that shape doesnt matter nearly as much as the size…

bought a 18" ftl fully loaded for daily, and i was wondering if anyone can design something for me. max dimensions are 55 in. x 20 in. x 26 in. doesnt have to be exactly those sizes, if i can go smaller i wouldn't mind at all. this is going in a ext cab f150. going to be used for a daily ground pounder. any help would be greatly appreciated.

Was wondering what would be the best options(in terms of loudness) in regards to size,port direction and sub firing direction. Space I am working with is Depth: 23 in Height: 26 inches Width: 42 inches So I can fit a decent sized box in it. car looks like That one isn't mine but it gives you an idea of what I am working with, but will have inside pics up tomorrow I appreciate whatever help I get.

i got bored and decided to draw this up, its right around 2.5 cubes @ 35 hz. gonna be for two 10's ( AQ SDC2.5's) Its gonna go in my chevy std. cab. Any comments or suggestions?

i just traded my one 12" MTX 8000 series for 2 10" MTX 6000 series (4 ohm). sounds like i got screwed but the 10 sounds so much better. now i want to get an enclosure for both because the guy i traded with only had an enclosure for one. the enclosure it is in now is about 1.1 cu. ft. it sounds pretty good, gets decently low and decently loud, but doesnt really exceed in either category. i listen to all kinds of rock and some rap occasionally. so i want an LSQ setup. i cant decide whether i want to go ported yet or not. i'd love to but not sure i have the money because i dont have the knowledge to build my own. i am just wondering what the perfect size sealed and port…

This is what i have came up with, i have the wood, tools, and these are the specs I found most best for the sub and is wondering if this would work prime with the AA mayhem single 12" dual voice coil. http://imageshack.us/a/img22/3130/subspecs.jpg

First post, Please bare with me. I did a search but didn't find what I was looking for. 2005 Ram 1500 Quad Cab My truck is all set-up with highs, deck, EQ, Kicker ZX.1000 amp (~1150W @ 2ohms). Looking to run a 12" BL Dual 1Ohm. I listen to mostly rap and hard rock, looking for a good box for the daily driver, I'd say mostly rap, real deep lows but I'd still like to hear the kick drums. I've never built a custom box before; I'm looking at 2.0 ft3 slot ported box @ 32hz. Will this limit the sub from reaching its full potential? The amp puts out real good clean power, I'd like the best possible box for my truck. Are there any pre-built boxes that will work well with …

So I will be ordering an OA-12v2 D4 very soon after selling my current system (Upgrading from a Fosgate Punch P2 12, 2011 model). I have a Rockford Prime P500-1d to work with, so the sub will see just over 500 watts. I have read in many places that the more power, the smaller that the box can be, and the less power, the larger you can build the box... generally. So I was thinking of doing a 2.5 cuft enclosure for the OA, on the 500w. It will be going in the trunk of my 2000 Civic sedan, most likely sub back, port side. Does this sound appropriate? Is there another way I should approach this? The box will be tuned to 30Hz via 4" aeroport. Thank you for any help, and I apol…

I will be fiberglassing an enclosure for my SA-15 into the spare tire well, but don't know if it will be happy in a sealed box. I listen mainly to hip hop and occasionally rock, so I want it to hit those low notes with some authority, but seeing as it has such a high F3 I'm not to sure if it will do that. Also seeing everyone else who picks up one of these ports it, I don't want to build a sealed enclosure to find out that it isn't what I want. I'd like to go sealed to make the install easier since it'll be my first time fiberglassing and building a box, and to save a little room and keep the design much simpler as I would like to maintain as much hatch space as I can.

Am trying to calculate the exact cu.ft for a wedge enclosure. I tried a few different sites and got anywhere from 5.8 - 6.0 cu.ft. Since I needed the exact size I worked it out by hand myself. Here are my dimensions and what i got. Can anyone double check this for me please? Wedge Design Outside Dimensions Height = 22" Depth 1 = 10" Depth 2 = 20" Width = 39" Formulas used: Rectangle L X W X D Triangle 0.5 (B X H X W) Since the design is basicly a rectangle and a triangle combination, thats how i calculated it. I got 4.12 cu.ft for the rectangle and 2.06 cu.ft for the triangle with a gross volume of 6.18 cu.ft. I also took into account that the 1.5"…

Its been a while since ive been on here... but i need some help... I'm building an enclosure for my new car (02' focus ZTS) which will house 4 10" woofers firing towards the rear of the car at a slight angle with the deck lid.. (ie 35-45*) question one... is this going to cause a lot of cancelation? question two... i want to build a seperate air chamber to fit the spare tire well... and connect the two chambers to increase my overall air space... will doing that actually do anything for my airspace considering for now... the box is sealed? thanks for any help -AcId-

im wanting to do a build using a mach 5 audio spl 12,sundown audio saz-3000d combo the question is ,will this be a good candidate for a mass loaded enclosure,or t box on the street. im very impressed with what peter w. kulicki has done with two soundsplinter rl-i 8s but i want to understand the enclosure more because id much rather build myself.

Hey guys im switching from CVXs to BLs im wondering if my old box would be ok with the new subs till I get a new one built. Car Tunes built the box and its suppose to be "spec" for the size of my truck and the space im utilizing. They said its a 1 chamber for 2 subs. I went outside and measured it...dual 15s btw 20.5in long 42in wide 18.5in high The port measured 2.5 in wide 16.5 long I just wanna know if this box is close to whats recommended. Im sure they need more port volume but I don't build boxes so someone enlighten me please lol. Any input is greatly appreciated guys! Thanks

i have a 93 nissan sentra and i purchased a bl18 how should i build the box to fit into the trunck withough compromising sound quality

Im about to do a build for someone and wanting help with the enclosure design. They are wanting a c pillar wall with port across the top. Its for one 21" warden on a sundown 4500. High output alt.

Hey guys. I need a little help designing a ported enclosure for my new Crystal CMPx2 15". It's going to go in the trailblazer for now. I listen to nearly everything so I'm looking for a good daily build. I could be off but I'm thinking I want to tune somewhere between 31-33Hz so I can get some lows. My size limitations are 46" wide x 16" high x 14" deep. I have a little wiggle room on height and depth, but I'd like to keep as much space as possible in the Trailblazer. I will post T/S parameters below and I expect to be running at 1500+ watts with maybe a little headroom, probably going to just grab a RF T1500bdcp, unless I get a better deal on something else. I'd really…

Okay this first pic is the side view. This is in my trunk and it will be set into my wheel well but will also go about 4-5 inchs above that level. My first question is; would firing my woofer into the back of my seats pose any significant problem or reduction in output? Also, can I place my port outside of the box extending into the cabin or would this potentially pose a problem?

I bought 2 aurum cantus ac165/50c2c to go in a 2 way active setup (morel 378s for tweets). The speakers are not made to run infinite baffle, but I figured I could make something work. I'm not quite sure dimensions yet for the door, but at first I was thinking of using those 6.5 foam speaker baffles that seal the speaker. I am doubtful that these will give them enough space or will be optimal but Id rather they be sealed in a tiny airspace then free air. I am going for sound quality in my front stage, so I want a more permanent better solution to this. Any tips on going about making an enclosure? Also to note this will be in a new chrysler 300 so I don't want to cut up t…

ok a couple of months ago i had woodlawn cabinetry build an ensclure for the subs that i thought i was going to use. well like a couple of weeks ago it arrived. and i really like it but the subs i had told him i was going to use i no longer want to use. so i figured that if the subs that i wind up using have a smaller displacement then the ones i was going to use then the port would be tuned a little lower and vise versa for bigger. now am i wrong and the ensclure is a 4.5 c^3 tuned to 33hz after displacement, common chambered for 2 12" ICONS. i want to use either 2 eclipse sw7200 or 2 12" aa aresanals powered by a sae1000d if u want to know.
