SPL & SQ / Fabrication

I have never seen this box design before. Anyone care to explain what this does?

O just for giggles i built a lil oh 3cu tuned to 34hz box. . threw it in teh car hooked it up and it gets loud about as loud as my sealed 2 sub box.. But the thing i hate hate hate is that, it only does this at the higher hz's. Like low low bass plays but it doesn't rattle anything ect ect... I think my 18's had me spoiled though and i could just be being biased, lol So to compensate for the lows what would be a better tuning for my needs..28? or should i just go back to 18's

I am getting 2 Fi SSD 15's and I am wanting to get some pretty deep bass out of them. So what kind of box should I get to get the most out of them? If ported, slot or round? tuned to how many hz? Thanks in advance ~MadroX

Hi guys, I 'm always trying to improve my system. I have a 15" xcon and a 1500 watts Sundown saz amp. The car is a hatchback toyota Auris, with a little trunk. I had a slot ported box with sub up and port up, at 3.5 ft3 at 32 Hz. This box was too big for the trunk, but I thought it was not the right one for my car. I've heared this same box in a smaller car, with the same setup, and it was ...insane. In my car, it was not really loud. I have, now, a 3ft3 sealed box, with the sub firing back ; I found it was better than firing up. So, here is my question : if I want to do another ported box, what would be the best choice ? Sub and port firing back, or sub up and port back …

please list your equipment and your top numbers, what year that happened, what meter, etc, and maybe what you would like to see in the future.

im starting my new box build soon and curious what size aero port to use. the box will be 4 cu ft. should i use 1 6" port or 2 4" ports i used psp-inc.com and both would fit with the size of my box. just curious what u guys would use!? Thanks!!

So im building my first box out of 3/4 mdf...what size bit and screw should i use? Also whats the best glue i can get...money aint really a problem right now so give ur .02...

Do any of you know what software 'HexiBase' is using to make his enclosures? https://www.youtube.com/watch?v=5VFx37kz5Ww It would be awesome to have a bit of a play around with it to see how my current system stacks up. Thanks in advance

To figure how much air a specific subwoofer should need using the information like, (VCdia: 1-1/4" *Impedance: 4 ohms *Re: 3.6 ohms *Frequency range: 45-1,500 Hz *Fs: 45 Hz *SPL: 82 dB 2.83V/1m *Vas: .24 cu.ft. *Qms: 2.68 *Qes: .61 *Qts: .49 *Xmax 9.25mm) and does any one know a good thing or two about designing t lines.

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

I recently found this box picture: I love how the port and the edges are rounded. I'm guessing that on the edges that they achieved that with a lot of sanding. I'm wondering how to shape the port like that. I'm considering remaking my box, to try to achieve something like this. It looks completely badass.

what paints and primers should i use to paint a subwoofer box i want it to have a glossy black look thanks -Irvin

what tunning should i use for my box , i need it for LSQ should i do, 25-30-35 or 40 ??

Ok so Im putting 2 12" xcons in the trunk of my grand prix gxp max dimensions are 35"W opens to 55"W 15"H 40"D. I want it ported what do you guys think would be the best box type of port which direction and so on I wont be building it but I also want the best and the builder Im using can do it. It is not a comp car however I play my music loud everyday and I want to be heard

Sup guys I have a few questions, I've seen so many different types of enclouser's for example Round ports Slot ports squared ports port for each side individual chamber Ok for my subs I have 2 12" dvc subs punch my max dimm. are 34 wide x 15.5 height x 17 depth all pieces are cut out already I want to know how ??? should I make my port round, slot ported, port in between the middle. tuned around 32 to 35 hz so that's about it so can someone please lay a hand on me all info would be great thanks to all....

Howdy, I am going to be walling the astro soon and wanted to get some ideas of what type of walls there are and whats the benefits to them.I am walling it with 8 18" icons I havent set the amp in stone yet but I am contemplating between a DC 12k or a Soundigital 16k. once again the amp is up for debate. There will be a multiple alternator setup with battery bank to supply the amp or amps that are chosen. but with all that out of the way! Dimensions I have to go with are 48" tall 51" wide and up to 97" deep but I really dont need that deep lol! we still need to leave room for amps and batteries! I was throwing around the idea of a clamshell or maybe a 4th order just not …

Never used allthread in a high pressure install so need some small tips in this area. I know that when allthread is ran from one side to another that washers and nuts are used on both sides of a wall. So that means 1 run of allthread will have 4 washers and 4 nuts on it. What kind of washers and nuts am i suppose to use inside of the box to prevent them from coming loose? I looked at nylon lock nuts but i cant use those on the inside because to get the nuts on the inside, you have to roll em on before you slide the allthread through the other wall. So, roll nut one way then back the other way to lock in place... nylon nuts appear to only roll in one direction so i dont k…

HEY JUST WONDERING WAT KIND OF NUMBERS I WILL BE LOOKING AT WITH 4 15' DB DRIVE IN A WALL POWERED BY A MASSIVE AMP IN A 95 INTEGRA

what is the best wood glue to use for building boxes i plan on using the gorilla wood glue

As per title lads, with my equipment coming soon I wanna go with the loudest design possible, will be using 2 AA Mayhems with 2 Hifonics 2607D's to power them, have a nice bit of room to play around with (say a max of 25-30cuftexternal) Will I go flat wall Port up top?? Flat wall port drivers wide?? Clam?? Small Tunnel?? I'm not really pushed about numbers as I want this to rattle people (will tune to maybe 30-32hz) All suggestions welcome guys

What type of design would this be considered? Would it have any disadvantages to a regular ported enclosure? Drivers would be mounted during the enclosure being built. Is there any negative effects by having the drivers facing each other? any cancellation? What would be a good distance to have between the opposing cones? The more the better? Thanks

Now that i'm playing the find-a-car game again, the beetle is back on my list, for price reasons. I currently have nothing planned (well i know i want thump, but beyond that, nothing) With a budget of $3k what is the loudest you could get a beetle, tuned low, to peak around 27-29hz. Back seats are optional. Would like a pair of subs, but a single badass sub wouldn't be the worst. everything besides the fabrication of the box, is done by my hand. This seems like a backwards goal, but my desired show off songs would be, like, Trunk Bang by dorrough and I cook - by OJ da Juiceman. If the low tuning doesn't murk the score, i'd like to be able to compete. Mid 140's would be a …

Just waiting on getting my two 15" icons and, since I have nothing better to do I was wondering if there was any box type or orientation you'd like to see me try in my 2004 Impala. I'm going to try a ton of different boxes and orientations with a lot of testing to see what works out best in my application and I wanted to have some fun with it. I'm NOT doing a wall, but ill be pretty open to anything else you'd like to see me try. I might actually end up using your idea if it works out the best! -Mike

4 IA 187s and two AQ 1200's or 8 Hifonics hifi12d4 and two AQ 1200s, this will be a old car(chevy celebrity type ) and walled. this will be my daily drive

What is considered the windowline in a competition vehicle? My doors and my trunk windows have a different height. Also, do they have no wall classes with a height limit vs the window rule?
