I have a pair of them,they were used mostly as interim speakers after moving as I did'nt really have room to use my CV E-712's
I powered mine with a JVC RX-318bk reciever.
Overall they're not bad for what they typically sell for,but IMHO they seemed a bit weak in the mids considering they're a 3 way speaker.
Pairing them with the Sony SS-B1000 2 ways seemed to help that situation somewhat,but even that did'nt solve the issue completely.
As for the lower end of the spectrum,they seemed to do pretty respectably in that regard,and the highs are'nt completely horrible either.
Honestly they're a VERY basic speaker,no crossover to speak of,just some blocking caps on the mid & tweeter,woofer runs full range.
And the cabinet falls a bit short in many respects as well,thin wall MDF,vrtually no insulation/damping material,that sorta stuff.
That said if one is not averse to some minimal DIY modding my guess is they could be modified into some much better sounding speakers.
Brace the cabinets internally,add some damping material,add a real crossover,things like that would surely go a long way towards improving them.
There are some posts out there on the web about modding these,I would tend to agree that would be an area to look into.
I dunno,some day I might get around to playing with mine just to see if I can surprise myself.
