Good Morning, Friend-Os!
I'm going to build two powered subwoofers to complement my Vistas Bottom end. I keep going back and forth on woofer selection, enclosure type and material, amplification, and in which order to choose them. I think I should choose my woofers first, and then build the enclosure around them, and finally choose my amplification.
I'm considering a number of possible driver manufacturers; Namely Scanspeak (Discovery 10", Revelator 9" or 13"), Vifa NE265W-08 10", or one of the Morel offerings (they have some nice offerings).
For the enclosure type, I'm leaning toward using passive radiators instead of porting, or sealed enclosures. I want these to be as small as possible, while still producing the low bottom end. It could be that a ported enclosure is the only way to go.
Stepping outside the box, so to speak, I'm interested in trying something very different for my enclosure material; Plastic, or more precisely, 1.5 inch UHMW. UHMW (Ultra High Molecular Weight) is very dense; more so than most hardwoods, and is perfectly uniform in its' construction.

If I go that route, the most cost effective way to build them would be 12" x 12" Cube (729 cu. in) or 12" x 24" (1701 cu. in). I know that the 13" revelators are a no go in that configuration, but maybe they're that good that I could spend a little more on materials to accommodate them.
For Amplification, I would like to use a simple outboard amp (Dayton SPA1000) to power both, or look into some of the offerings for In Wall subs for other manufacturers.
Here is where you tell me where I'm making mistakes and over-simplifying.
PS: Is there any inexpensive software available for enclosure design?
