SPL & SQ / Fabrication

hey guys...just wondering what u guys would recommend to use or have used to keep your box from sliding around? i have a trunk car so mine just moves all over the place...? velcro? l-shaped metal corner brackets? open to ideas...

currently running a sundown saz1500 powering a fully loaded 12in fi bl in a 2.5 cu ft box tuned to 34 hz. I was recently at a local audio shop and had the main guy set my gains properly so i did no have any clipping. I was not very impressed with the outcome. As i come to find i had been running with clipping since day one and my system is now quieter. He told me to tune my box to 40-42hz and it would be louder. My question is how much louder? and will i still be able to play most rap music? What would be the lowest tone i could safely play?

Hey guys I have a couple questions. I did a build on 2- SA-12" V.2 Nightshade and I had a custom box built that is 3.0 cf box w/ a port face that is 40x1.2" and is 23" long (specs I got from SA). The subs are firing up and the port is firing back at the bottom of the box. This roughly give me 48 inches of port tuned at 36 hrz, I heard from SA tech that I needed 15 inches of port for each SQ FT. It sounds great, the only problem is it doesn't sound as loud as my ProBox super bass box did. Any suggestions? I talked with SA tech again and they said raise the tuning frequency by cutting off a little off of the port. I checked with ProBox and the Super Bass Boxes are tuned at …

sorry if this is in the wrong place, i wasnt really sure where to put it. move if needed. i just know lots of RE questions get asked so i'd thought i'd start it here. i posted the same thing on caraudio forum and thought i might as well post it here too. if anyone has any ideas i am open for anything. -getting around on a build for an 18 inch 2005 xxx. ive done some searching on box sizes and such for this and i am thinking... 8 cubes 34 hz 115 inches of port do those numbers sound about right? bigger box? more port? this is going in a 97 grand marquis...huge effing trunk...FTW amp is a saz1500 i was also porting the rear deck and taking out the back deck speakers. was t…

I am wondering if the Mach 5 SPL-12s would be any good in a T-Line? I have been told they should be good, but the fs is sorta high. I am planning on doing this with my camper shell but with a different box... the box can run the length of my truck... I plan to make up some metal frame for the box to sit on inside the bed. Having the box above the floor will give me room for my air ride when that gets installed..

I was told by a former "audio guy" that althought 3/4 MDF is used in car audio enclousers, 3/4 partical board could be used to reduce the weight of the encloser. How tru is this?

I was wondering how to build a ported box for 2 18" btl loaded each one in its own chamber for a 03 Yukon and how to tune it between 30 and 35 Hz. I'm looking get some serious bass. What are some dimensions I can use with the speakers facing up? I will be running them on two saz-3000d. Hello again I'm looking for spl in my 03 yukon. I am looking at running 2 Fi Btl 18" on 2 Saz-3000D amps in this amount of space. H 21" W 46.5 D 22-28". So what do you think? I need help with the box and port dimensions. Once I have an idea I will start the building. I need all the help I can get. Thanks

I was wondering if anyone has ever seen a port like this? Is it even possible for this thing to opperate properly, it still sounds great, but I'm starting to think that its just the DCON making it sound good.

I did search 'box carpet',and you'd be amazed (sarcasm) how much those two words are used on this forum. lol, i went through about 15 pages and found some good info on where to get it,but i still have one question. A lot of people said they got their carpet from a hobby store,and i'm just curious what kind of carpet to look for when i get there. I could be wrong, but i don't see them having "sub enclosure carpet", so i really just need a name to call it... If i can't find it at a hobby store, i guess partsexpress.com is the next choice ($5.85/yd... much better than crutchfield's $30 for 3yds.)

Putting this into a grand caravan, middle seats up, backseat stowed. Going ported, thinking 30-33hz tuning wise, any recommendations? Going to run it off a Sundown 1500d, so box size recommendations? Also, will be running the stock alt for awhile (160 factory). Doing my big 3 upgrade with 1/0 and a single run of 1/0 for now....later upgrades will be wiring and alt before anything else...also no sound deadening for now...also looking for any recommendations for sub/port orientation? sub/port back towards hatch, sub up/ports toward hatch, sub up/port facing side....anyone with experience in a minivan would be nice, not that most of you have one, but a guy can hope lol. than…

picked up a pair of 12" iCons and this is the box I plan to build. I was wondering what you guys think. This is the first time I have run anything other than a single 15" or a single 18" so I want ot get opinions before I build it. 4.8ft^3 net air space (5.12ft^3 gross .16ft^3 displacement per sub) tuning 32hz-33hz 72.5in^2 port area

I need to build a slanted box and obviously the port is going to need bending. Should I go with a labyrinth port or an l-shaped port ? How do I calculate the lenght of the port, because the top part of it is going to be shorter than the bottom. Should I average the lengths ? A couple pictures might help... To my understanding that would be an overall length of ~40cm. Am I right or am I terribly wrong ?

Hey Guys Call me a NOOB or Whatever you want, but i need your help, i have tried Kicker L7's, Pioneer Premier Spl, Alphasonik Mayhem and not really achieving alot , only the kicker sounded good but you only get one type of bass, now i want to set up a system thats gona be loud outside and shake the ground, i need your help here because i'm gonna try FI's should i get BL's or BTL's and should i go 2-12" or 1-15", i have a 09 sonata and currently have a MTX TE1501D amp but will upgrade to MMATS 3000.05 next month my trunk is huge but i still need cargo space, so i'm willing to sacrifice 36W x 17H x 19.5D, can you guys plz help me with a box plan also, i listen to mostly r…

ok so between my 2 15's im going to have about 400 square inches of port area, and i need to know if figuring out tuning frequency is the same as like a round or slot port. or if 400 is too much lemme know. i have figured 355 per sub so 2/3rds of that is about 220 per sub. but the box is going to be aboue 3.5-3.8 cubes per sub and i would like it to be tuned to around 35 hz. but i have no idea how long i need to make the port or anything like that. so any tips or tricks are well appreciated.

Who's Going,? im not, ill be in Key West, but if there is enough interst in the people who are we can have an SSA meet prior to SBN. Kickin', i know you are going, stop by my house on your way so i can hear 150 Certified on TL.

I recently changed the enclosure of my sub. Nothing else has changed : same electrical, same amp,... The old one was too small, and badly tuned (too high). The new one is really a good one. When I made the change, I was not so happy with it. And after a few days I start to like it more and more! Could it be that the sub need to adapt to its enclosure for some time before playing as it should ? Maybe I am just getting used to it! What do you think about that?

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.

I have 2 Orion H2 12.2's to be powered by 2 Orion 2500d's and want to build an enclosure for them,the only problem is i'm not sure of the air space to run.I want to shoot for max spl,i was told 4 cubes per sub tuned @34 hz is prime but i'm not buying it.Any help would be appreciated,thanx!

Sorry for the long post. I just bought a pair of Beals Bros 8" midbass drivers. I have no specs on them. I know you are probably saying to yourself, why would he buy them if he doesnt know anything about them. Well they were cheap and in great shape. Now on the the questions. As many of you know I am currently running a set of CDT HD-62 pushed by a Memphis 16-mc300 ~150x2@4ohm (depending on voltage) ~240x2@2ohm ( " " " ) Here is where the questions start. The Beals is 2 ohm nominal and the HDs are 4ohm. that would make the final load 6ohm for series ( not enough) or 1.3ohm for parallel ( too low). I have heard that lower impedance=more distorti…

I sm trying to get my trunk ready for everything but before I start deadening I need to decide what to do with my spare tire well. I know I cant leave everything in there cuz it will vibrate like a mother. But if I take everything out there is just a big hole so what can I do to cover this that won't cause any noise?

What do you guys think of the design? Its for a DC lvl 4 12'' sub How would I factor in a kerfed port to the design??? If the kerf is secured as an external portion of the port, will it affect tuning or require a change in design anywhere? Specs come to: -2 cubic feet before subs displacement -32.5hz tuning -36.25 sq inches of port area

I wasn't going to do anything to my 2005 Chrysler 300c but that has changed. I have two ideas and need some suggestions. I'm replacing what is there now with a Fi BL15. Plan 1...sub firing forward into the cabin (cut out armrest hole and aim through there), port through the deck and seal off the trunk completely. Or plan 2...fire sub rearward port probably up (not through deck). In either case I don't want to go any deeper than the folding floor (approx 24"). I ran the numbers and can get 3.5 cu ft (after displacements) and tune to 33hz. I prefer sq but like it a little heavy occasionally. I listen to all kinds of of music but am thinking this setup will really sh…
