As some of you might already know, (and if you don't, look at my sig), I have four 10s in my trunk in three separate enclosures. It looks really clean and has worked for a long time, but I'm tired of it. I want to keep the same subs and play them until they blow, but I need to repackage them in a different enclosure. What sort of box should I build (can I buy?) that will accomplish this? What shape would fit my four subs and still leave me with a trunk to speak of?

The most important point for me i weight reduction. 3 MDF boxes weigh quite a bit, and that's without the subs.

Second most important is type. I've used sealed before and like the precision, but I also like the loudness from ported. I've never used bandpass, but I don't know if I want to.

Any/all input welcome.

 

boo on bandpass..... there one note wonders.... if your concerned about weight your gonna have to stay sealed ..... the other option is to go way old school and do a isobaric
setup.... there not for everybody but setup correctly they work

 

Bandpass boxes suuuuck. There's absolutely no accuracy. Sure they're loud as heck, but don't you like to hear your music? :P

I made my own box out of 3/4" MDF. That said, I only have two 10's. A friend of mine had a rather uhh... interesting box. It was one box, four chambers, two subs facing back, two facing forward. It sounded okay, but he had cheap Walmart Pioneers in there.

For weight issues, you can use 1/2" MDF depending on how powerful your subs are. It should effect the quality too much. There's also always plexiglass boxes. I've never heard a system with them though.

Here's my box:

 

What the heck is an isobaric? Time to google it...

[edit] Thanks to the12volt.com, I think I'll pass on that. Requires odd boxes and makes 2 give the same output as 1. Got 4. Might as well use them. Thanks for the info, though.

 

Agreed. I helped a friend put one together and hated it.

Those are some big amps. Bet that bumps like crazy.

 

I know I'm new to the board, but coming from a car audio background, I feel the need to interject.

1) bandpass boxes are not one-note wonders. Just because the pre-made ones lack a smooth response, and building one well is very hard to do(I had a hard time building a 6th order dual reflex bandpass box not too long ago), does not mean they suck. You can get a really flat response that can dig down low and still extend well to blend with your door speakers...it's just hard to design and build.

2) As far as weight goes, try using eithet Trupan or birch plywood...both are considerably lighter than MDF and every bit as strong. They just happen to be a little more expensive.

3) If you want to still have room in your trunk, I'd stick with sealed boxes...you'll end up needing twice the space to port them properly.

 

Pretty decent. Its crystal clear... no overpowering bass at all. Ones a 550 watt 2 channel, underpowering the subs pretty badly... lol Then the other is a 450 watt 4 channel that powers the front and rear speakers. 5.25 Power RF's in the front, and 6x9 3-way RF's in the back. Then my tweeters are stock and powered by my HU. Nice and clear. :P

 

try flush mount in your spare tire well and keep the side ones... what subs are they?
