I had some bigger Crowns, but gave the (2) PSA II`s & (2) Power Tech 3`s to my B-I-L, who lives next door, to help him upgrade his excellent sounding, but cobbled together, quad amplified main system, also because there were nowhere to store anywhere here, the big & heavy 240 volt rewired and unused power amplifiers..
