SPL & SQ / Fabrication

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.

Working on some fiberglass corner enclosures on an upcoming build for someone and i noticed that the corners that they will be installed in are slightly different. since i was going to begin by making the backs to rest perfectly flush i am wondering if having slightly different airspace for each side, say .1 of a cubic foot. would cause problems. I would say the left box will be about .9 sealed and the right would be about 1.0 if anything. should i add an extra piece of MDF to the bottom to compensate? i didn't know is the different Fs would cause some type of clash in the response

i've posted this in other forums too, im just trying to get as much input as possible. this is for tc3000 12"dvc. several experienced people have recommended around 2 cu, but i've done some more reading and it seems that they recommended for SPL purposes, you want to use a large enclosure and port. But im not going all out SPL, i just want a REALLY LOUD daily setup, so im just going to experiment and try something in between. I've decided to go ahead and try 2.75 @ 33. i chose to use 15.5 sq in per cu ft since 15 and 16 seems to be the commonly recommended multiplier; the port area comes out to about 42.62 sq in. my max height is 13.5 so my width is about 3.157. i used th…

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

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.

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…

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:

Has anyone ever used it? How does it work? Is it worth $17. I want to spray the inside and possibly outside of my sub box with it but I don't know if it is worth it. Should I just get some spray on bedliner in a can and use that instead? I was hoping it would created a better seal and add strength to the 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 am building a box for 2 XCON 18s and am trying to get as close to recommended specs as possible. box is going in a 99 Durango. i really want my subs facing forward so people can see what they are feeling! But not sure about where to place the port. SSA recommends 100 inches port area for each sub, so only real options on location is on the front, bottom; or facing the back hatch. i noticed a lot of street rides have the port facing the hatch for whatever reason. any input/suggestions will be greatly appreciated

just started my new build for my fiance's brother the box will be for 2 jl 10w3v3's

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.

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

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

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

looking to do a new box and wanting to know what yall think the best kind of box i sould do if im wanting to seal off my trunk, i have 1 15" zcon on 3000 watts, i was thinking of doing a bandpass where the subs sealed part of the box is where i open the trunk and ported through where my back seats fold down, any questions? sugestions? im wanting to do this because my box now is ported back and sub back and my trunk pretty much opens with the bass and can feel mass air coming out so i know i can get way louder if i seal my trunk off

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?

So after much searching throughout the internet I still cannot figure out how to make a crossover. All I want to do is put a 12db/octave high pass on my 3.5" 2 ways at 500hz and a 12db/octave low pass on my 6.5 midbass at 500. All speakers are 4 ohm. I dont know if I need a capacitor and an inductor for each crossover or just one for each. Can someone please help explain how to do this or hook me up with some site links? Please and thank you in advance.

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

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. Best suited to subs that work best in sealed boxes. 6th order: rear chamber ported. front chamber ported. Best suited to subs that work best in ported boxes. Dual-bass-Reflex: rear chamber ported. front chamber ported. front and rear chamber connected by a third port. Best suited to subs that work best in …

o.k. i am not happy with the numbers i am seeing from my wall.so my q is can i cut a hole in the back wall and take it in to the trunk or make like a C in the back to make it deeper???i know it will change my vent and tuning.i am not worried about that.

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

What's up guys, I hope this is the right section. Having trouble figuring how to do my front stage in a 06 Charger. So I wanna see pics if any of you guys have a serious front stage in your Charger Magnum or 300. Also for this who wanna help, front door has a 6x9 which I have looked at and can make adapters for a 6.5 that's no prob. Now the dash has a 3.5, where I can put a tweeter or supertweeter. But that's not really what I want, I don't think a tweeter facing the windshield will sound any good. I have space on the door for a regular tweeter, but j still would like to see others before I proceed. Further notes, I can't fiberglass (would love a pillar tweets and mult…
