Took about 5 years off, began a build today: Utah V12 RXC21s

High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

I've had the wood cut for almost that amount of time and either I was deep in some electronics projects or being worked on by doctors needing new cars.

These are 12" woofs, vintage 1974, with an Fs of 27 and 94dB efficiency. I'm going 'acoustic suspension' 1 1/2 cubic feet for old school book shelf type. They're kinda boomy in a vented enclosure and now that I'm in a townhouse an F3 of about 60 Hz with a sealed enclosure roll off is just fine.

Tweets are SB-29s with a first order 10uF cap. .5mH coil on the woofs just because.
