there you are sir.

 

wow good site thank you very much

 

i made a 5 cubic foot enclosure using that program and it worked good, everything fit anyway. just make sure you make it deep enough for your selected driver, wouldnt wanna put it together only to find they dont fit....type r's have a rather large motor on them...

 

hey i was watching unique whips on the speed channel and they filled their boxes with sand to make it better, have you ever seen this done, and would you recommend it?

 

cant say ive ever heard of them using sand, but polyfill, yes. that fibreglass insulation dealy stuff.

the sand seems like such a bad idea unless it solidified, obviously its making the internal size smaller, but beyond that i have no idea....maybe bob, or hillbilly knows....

 

I've never heard of that and I would definitely not do it. You would lose air volume and the sand would probably ruin your drivers. Building a subwoofer box is simple, I've built several. You need 5/8" or 3/4" MDF (preferably 3/4"). You also need wood glue, a jigsaw, 2" drywall screws, a drill with drilling bits, a circular saw, and a speaker terminal cup (or two depending on you amp/sub setup). It's pretty easy, and you'll learn a lot as you go. If you decide to build a box, I'll give you instructions and answer any questions you might have along the way.

My current setup is 1 12" Rockford Fosgate P2D412 and a Rockford Fosgate Prime 500W RMS Amplifier. It's in a small bandpass (ported) box, and it is so loud that I frequently have to turn the music off. Two 15's set up right would be super overkill. And it would cost a lot of money. I suggest a setup like mine. The amp is $200 and as far as I know it is by far the best amp anywhere near 200 bucks. The sub is sick as well, I bought it because the JVC Arsenal sub I had blew, and it was rated 100 watts RMS higher than the sub I have now. It wasn't as loud as my new sub, and it cost like 100 bucks more.

Let me know.

 

Hey thanks I think I'll just get one sub in the back now.
