SPL & SQ / Fabrication

ok so i believe my sub box is about 1.08 cuft or very close to that. if i was to add this kit here... http://www.madisound...products_id=711 you think that would fit my application? in order to get 34hz with a single 3" inlet im going to need a "13.06364" long tube. if i got this kit i could cut it to length? what do you think? with a box of that amount of cuft do you guys think i should tune to a different setting aswell? let me know what you think!!

I had so e spare time on my hands so I figured I would relocate my switches and bass knob. Let me know what you guys think!!!! I'll get some pics of it installed tommorow!!!

Wondering what numbers you guys are hitting with your XCON trunk cars?

I found a formula that seems to work at http://www.caraudio911.com/ under designing a ported box. But I was wondering why on step four they say to subtract half the port width from the port lenght to get your physical port lenght? When I made my box I dont think that I did this so I may be building a new one if this is important. I was also wondering if this formula works or has been used by anyone here?

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.

hey so is there any one here that can desgin for me a ported box. If you can design it, tell me and ill send message you the information for for demnsioins

So the plan was to build a trunk box that was larger with more port area than the box I had previously but I ran into a bit of an issue much too late in process.... After we finished the box, I tried to slide it into the trunk. Didn't fit Damn you Corolla and you're itty bitty trunk opening. Inside of the trunk would have fit it fine but it could not be fit through the opening. Sooo, I have another backseat box. LOL It sounds insanely better which is a plus, but I guess i still fail a bit in the end. It'll do for now... 4 cubes @ 31hz, 18 sq inches of port per foot. Tell me what you think. (Besides telling me it needs to go in the trunk )

hey guys have 2 18" smd subs, have xtra cab f150,trying to do NW have 20d x 24h x 57w so i have 11cuft = 5.5 per sub,trying to get into the 50's but i cant seem to get there, any help appr.I have interchangeable port spl port 17x 13 thats the biggest i could fit, subs up on passenger port up on driver,double 13 ply birch all of box,running stetsom 7k2d 4xs power batts (2700's) 1 h/o alt ohio gen.4 runs 0 gauge 2 pwr 2grnd to the 3 batts in rear,should i just go for the wall? i'd get about 20 cu ft. SSNW1-2. ANY HELP THNKS

Can anyone give me a fairly straight forward design for a bandpass box for two 5 1/4" woofers? I like the one i have, but it is uber ghetto (Current Box) I would like to have it peak around 28-30hz for chopped and screwed music, but maintain some punchiness on higher notes. Box size isnt really an issue, the one i have currently is around 9in tall, 4ft long, and 3ft wide. I like the style of mine, the way it is laid out, chamber, port etc so anything similar would be perfect (i might use a plexi top; If i do go with the plexi, i'm spraying the insides flat black). I will build it myself, out of 3/4" mdf and some bracing. Only requirements are is that it must be at most 12…

I am going, and I know team gates a a bunch of other big guns will be there, anyone else from here? I am rolling with Ray and the Caton Customs crew, but I am not going to show, I dont have time between then and now to prep my car, nor are my pods built yet

I have really thinking about trying to run surround sound into my car but don't want to spend very much I want to keep my active 3way system I should be wiring this week, cross-overed in my deck I like my alpine 7998. What options do I have no cheap junk like pyle please

could someone please double check these numbers. I know this box is small but that is all i have to work with and its still at the minimum.

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.

im really thinking about running some dc sounds gear 6 12's or 4 15's in a wall. what do you guys think of box/port sizes for a bass race set up? also does anyone have any spl numbers with there subs?

Hi I need help making a spl/daily box for 4 15s, I'm going with subs ip port back and want it to be crazy loud, I have 3500 rms going to all of them how should I make the port and what to tune it to?

Im starting my build in about a week or so and i narrowed my design down to two options. The first option is to have the sub up firing at the rear deck with a kerfed port(s) firing back or sub up firing at the trunk lid with a kerfed port(s) firing into the cabin. after doing a lot of searching i see a lot that like the sub up port back. The reason i chose these two designs is because i cant do both sub and port back or sub back and port to the side. Which option would yield better results? I also its vehicle dependent but my box will have to be build inside the trunk so moving it around is pretty much out the question

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?

Ordering a AudioControl DQXS digital processor sometime in the near future. All the speakers I have are in my sig. I need suggestions on where to place these bad boys. Two 6.5"s are going into the bottom of each door. for the 4s and tweets do u fellas suggest I do 1. midrange/tweets in doors and a-pillars. 2. doors and kicks 3. kicks and A-pillars note: each 4 will have a tweet right beside it, so it wont be off axis

A buddy of mine came to me the other day with 2 15s and wanted me to make a box that would fit in a 1999 Buick Park Ave. With a Height of only 14 inches its gowning to be a Wedge Enclosure. My ? is should i port the box in the front or in the back? The back seats do not fold down but in between the seats the arm rest folds down and gives a quick access hole that is 8 1/2 x 7 1/2 to the trunk. I was thinking of putting the port right there but im not shore. pic of trunk access hole http://memimage.cardomain.com/member_image...9377_5_full.jpg

if ny one has ann ideas for a box design that would be helpful please post them!!!! i need a good idea for the SPL competition!!!!

I have an 02 mazda protege sedan I'm planning on making a custom kick pod out of fiberglass for my front doors. I'm going to put my hertz mlk 165 (6.5'') midbass component drivers into the kick pods. Will be ran off of an eclipse EA4100 amp bridged to 150w x 2 (for now) I like listening to rock music with a lot of bass around 80 hz. My sub is a dc lvl 4, ran off of a sundown sae1200, Right now its in a ported box tuned to 32 hz, but I'm probably going to be building another box sometime (idk what kind) what type of enclosure would be the best encolsure for my midbass drivers? I can make a sphere-shaped enclosure; does shape matter for a sealed box? while we're at it, what…

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…

Does or can anyone help me figure out what kind of space is needed to run 2 12" Z V.2 subs in a 4th order in the trunk.

i will be running 4 skar 10's, the box will be in an extended cab dodge dakota, the rough dimensions of the box will be 48" wide, 26" tall, and 15" deep, subs will be on top. now i know if the subs were on the front pannel i would double baffle because of the amount of surface area there is on that panel, but if the panel the subs are on is only 48"x15" would i really need a double baffle? i mean of course i will brace is with allthread or wooden dowels, but i dont want to double baffle if i dont need to, mainly becase that would require me buying an additional 4x8 sheet of mdf.

i got a box that is 40x32x17 and trying to tune it to 32hz can someone help me find how big i need the port hole
