HT Subwoofer build ideas/question

[MikeCamp]

I'm looking to save a few bucks and have a fun project to do all at the same time.

Here's what I've come up with so far.

Company called Elemental designs sells a custom built subwoofer for $1300 plus shipping.

Interal parts are

1300 watt plate amp = $350

18" subwoofer = $195 (I would think dual 4 ohm is what I need?)
http://www.edesignaudio.com/product_info.php?cPath=21&products_id=37

Total = $545


The box 25x37x25 (ported)

Any ideas to help me build the box? This is what their $1300 box looks like. Anyone here make a box similar? Do I just use PVC for the port tubes? Thanks for any help ahead of time.

An externally hosted image should be here but it was not working when we last tested it.

Hi Mike,

The amp is looking for a 4 ohm minimum load so I would suggest the dual 2 ohm wired in series.

PVC or ABS pipe are both acceptable for the ports. Is that really 3 ports I see?

Yeah... here is a pic I snagged off another forum of the finished product.

Huge!!
