High end of the 22 series Energy speaker designed in 1982 and lasted several years. This model of the 22RC had a frequency response of 25Hz to 45Khz with a 1 inch tweeter and 7 inch woofer. This speaker broke new ground for design in the early 80s. There is also a 22 Reference and 22 Pro. This one is the high end RC version. It had a built in stand support, while the lower 22 models needed a stand to sit on.
I own a pair of these and they live up to their reputation. I have yet to hear a better home speaker! There is a pair on eBay right now going for $3,999US and another repaired pair that didn't meet the lowest reserved bid at $180US. Go figure!
I bought mine in Canada in 1982 and paid $1,200CAN. The hyperdome tweeter is amazing and the relatively small cabinets (mine have a dark walnut veneer) produce a bottom end of 30Hz (which is exactly what the specs claim). No sub woofer required, although I do have a Sunfire (with 2,700 watt built in amp) for the full bottom end. I power the Energy towers with a vintage McIntosh 2100 power amp and the McIntosh C35 pre amp controls all. This system rocks or whispers and these references speakers make it all work.
