I've had these up and running for a while at home and I really don't like to call them "subs". they just don't sound like "subs", no boom-boom etc. they are more a low woofer, very, very articulate, they do the deep notes as needed without adding any unnatural oomph. just what I was looking for. I think I'll be referring to these as bass modules.
anyhow I'll be posting the prices on the site soon but here's the quick breakdown.
btw these are introductory prices for now...
the 1X12 is $2290 ea $4150 for a pair.
custom active low pass XO is $950 and the passive high pass is $450
complete package $5450
the 2X12 version will only be available as a complete package at $9600 for the pair with crossovers.
I'll write more about power amps soon, but one of the best I've found so far is the Parasound 2125 amp. plenty of power for a pair.
