Default okay im going to build a rack in my van for work...

This being the case i'm going to incorporate a sub enclosure into the part i wouldnt be able to reach easily.

the space available is 18"h x 15"d x 48"w

requirements

2.0pi flat to 20hz, i listen to alot of music wich requires cone control to 20 hz and output there.

.5pi output to 120 db, its in a van so i expect a 12db/octave boost below approx 100 hz due to transfer function.

id like to keep the amp small so around <250w would be great.

A tapped pipe or horn, NO PORTED OR SEALED WITH EQ PLEASE, BEEN THERE DONE THAT GOT THE T-SHIRT SOLD IT ON E-BAY, NO WIGGLE ROOM HERE. I have this room to use so I'm going to use it.

I want to order the driver from parts express so that's the only place to look, buyouts or whatever.

if you want i have hornresp and don't mind doing some tooling around if you want to drop a driver model your familiar with on me.

Driver budget up to $100 plus shipping.

Pretty sure you should do a properly designed long excursion 10" or 12", PORTED, in that box size to get that kind of extension.

Start HERE

It is a relatively simple to use program and very powerful tool.
