SPL & SQ / Fabrication

This may sound like a stupid question, but I have yet to find someone who can give me a good answer to it: How do multiple drivers react when installed in a single undivided sealed enclosure - with regard to (Fb/F3 etc.)? For instance - Say you install 4 12" drivers in a single undivided 4.0 ft3 (Net) enclosure. Do the woofers react as if each driver was installed in it's own 1.0 ft3 box, as if each was installed in it's own 4.0 Ft3 box, or Somewhere in between? If so, is there some easy formula to calculate the volume that each driver "sees" to determine box response characteristics? Thanks, Hans

the back window on my 2000 ford Explorer is Mage Flexxing !!! what can be done to stop the spl from leaking out ???

if you havent seen how small the trunk is on this car, motor trend stated specifically that it was about 7.1 cubes TOTAL! i cant lose the space under the floor because there is no other room for amps/batteries, and i have to leave about 10 inches from the box to the very back of the trunk for tools and etc. with this said, the question is; what is the best design and setup for maximum SPL with keeping it in daily drive limits? i worked up a few partial boxes and havent really made one that pleases me yet. the biggest so far is two seperates (against rear seat, L and R) 1.6 cubes, each for a 12". sub must be on a mild angle toward trunk lid. is this adequate for a sub li…

Lets see em guys. I wanna know how you guys cram bass into these small areas. Post pics of your single cab setups: amps, speakers, whatever...

looking around for some round tubing to fit an 18 inch sub, i had seen someone who has done this befor on the Mach 5 Audio test bed site but I cant find that site any more. If any one has done any thing like this befor tips and how to measure air space would be a big help. Thanks.

I am pretty serious about doing a blowthrough to my F-150 in the next few months. I am pretty settled on 2 18"s on 4000 watts (will be more with upgrades in the future.) I was thinking of a 4th order bandpass box for them but I want to be loud on low hertz (like around 30-35). How can I accomplish this? Also, what would be better: 2 18" or 4 15" all on 4000 watts? Like I said, I want to be loud but hit low.

Does anyone know of any way to install subs into a chevy avalanche and still have the midgate useable? I use the thing like a truck but still want to get at least a 12 into it. I also have 3 kids so losing a seat is not an option. Help.

hi, i am thinking about having woodlawn Cabinetry build my box for the 2 12" Icons and i am wondering if anyone has had any experice with them. i would build it my self my i have no tools and he only wants 205 dollers for it and thats with it carpeted and i wanted the baffle to be laminated black.

what you guys suggest? i mostly hear 2.5 net for the 12. power is 2 kx1200.1's strapped, so at least a good 2400w rms. ive already taken all the measurments and everything, this is about 3.8 gross, so i may shorten it a little, leaving me more room for amps on the top. port- what should i tune to? its for rap music. slot? aero? heres sorta what its gonna look like. the yellow will be double 3/4"

ok well I have been toying with the idea of 2 15's in a wall in the bug (13cf gross) but will that much air movein in their cause cancelation or something that would hurt my score more than help it. I also only have usaci comps up where I'm at so I am allowed to open my doors and such just woundering. Thank mc

im planning on building a spl box for my 12" BL and would like some input from people with experience on a basic design to work around. for an spl box, i know people sometimes use a smaller box with more port area. my daily box is at 1.8ft^3 tuned to 33 with 26.5in of port area. approx how much port area would be ideal for this sub in say, a 1.5 cu ft box? im powering it with a hifonics bx1606d @ 1ohm and its in a 97 4runner, so anyone have ideas on tuning freq also?

Ok, well I just got a newer vehicle (2001 chevy tahoe). After spending my limit to upgrade my substage, I had my alpine 9831 from about 2-3 years ago die on me. I am thinking I'll get a cda-9887 to replace is since it will be pretty much a drop in change, and I can save some of my older cables. I'm really not that happy with the eq it has, so I'm considering adding one in there. I've never done this before, and while I've been researching it everyone has a different opinion as to what I should look for, so any suggestions will be appreciated. I have been considering adding 2 sets of 6.5 components up front, so I can keep my factory look without a large pod sticking out f…

My dash is pretty much completed. It's built to be very flat from a-pillar to a-pillar with no erratic or uncontrollable reflections. I have some ensolite ready to apply but need to consider an aesthetically pleasing way of covering it. I have considered a few different materials.... Vinyl - I would love to wrap it in vinyl, but that would do nothing as far as taming reflections. Suede - Not bad for managing reflections and certain kinds are permeable, but good suede is expensive and looks like crap as soon as it's touched. Tweed - Permeable and manages reflections well, but ugly as all sin, in my opinion. Any thoughts on a good covering material?

I plan on walling off my 00 Grand Am soon with 2 18XXXs (05 model) and I was wondering if anyone could help me out. I have a couple measurements... 41w x 34d x 34h That's the external (gross) measurements. I plan on tuning it around 30hz. I was also wondering where to put the port. This will be my semi daily driver (I have 2 vehicles), and I am not looking to hit any high numbers. I want this thing to get loud and low. Also any kind of tips/pictures/diagrams/explanations/ect. for a wall and dancefloor would be greatly appreciated. And yes, I have put some effort into this by reaching out and contacting many people so please do not respond in here if I have already …

Sooo, it is time for some ass time in my car seat tuning the system. I need music! Every genre (besides rap please). If you have links to some FLAC torrents of said media, please link me!

ok i am pending the idea of having an amp rack instead of a backseat ( it depends on the qoute i get) and since the amp's would be in the open i was thinking about totally enclosing it and having the top back pexiglass so since i think to think totally through i was looking at ventliation for it since has been hot out latley ( i live in florida) and i am wondering what others with amp racks have used to. first i was thinking 12v fans but then i thought that i would need a exit hole for the air to move out. then i started looking at Liquid Cooling for computers since computers are 12v. and that is all i could think of.

im would like to know if port are is THAT important. freind of mine has a BL 12, he wants to buy a box that another friend built, but the port area is under 12 sq inches per cube. the sub that was in the box before sounded pretty good. just wondering if the port are being a lil small is restricting output or SQ in any noticeable way. its off by like 8 sq inches. thanks

Im looking to get a good SQ setup. Ive narrowed my options to the SSA Icon 12 or a Fi Q 12. Whichever one I get will be powered by a Cadence TXA-1000D amp. I cant decide on which one, hopefully somebody here will be able to help me decide. I listen to hard rock/metal almost exclusively and I drive a 97 2 dr Exploder. So, which has the best SQ with the most output? Thanks, Mo Also, if I get the BP option on the Fi Q and still just run that same amp would it make a difference?

I currently have Rainbow Cal27 tweeters and Rainbow Profi Kick midbass. I am looking for a midrange to make a "hybrid" 3way frontstage (that words seems rather redundant ) I have a profi crossover and the intent was to place the tweeter and small dome midrange quite close to each other in the kickpanel, while the midbass is in the door. The midbass will be in the door. The specs on the midrange need to be a 2" dome with ~ 1" mounting depth and 4 ohms (because of the crossover, I am unsure how the crossover point will be affected by an 8 ohm midrange. I feel that my 880 should be able to t/a the midrange and tweeter because they are so close together, they will act as on…

MUUHAHAHAHAHAH

I know it's a long ways from anywhere, but if you happen to be close by.....come bump w/ us!

Ok so i'm pretty much done wt my box, will post pics soon enough, but. I'm not going to be able to reach my subs, once done, so if i connect each + and - to a bolt and nut on the box, that should work just fine correct? I'm sure i've seen it done before. I just would rather not run long lengths of wire to the amp.

where should i start ? i have a newer truck 1996' 2 door Chevy 2500 x-cab. bench seat 60/40 amp is a Massive p3000.1 subs are Pap WMD-SPL 1000rms ea. anyone have expierance with this truck ???
