GMA Callisto feedback Green Mountain Audio

Hi guys, I own the Europa's and have had them almost two years. Let me tell you your in for some sonic pleasure as they break in fully. This takes around 1000 hours, regardless of what others might say. At that 1000 hour point they become quite seductive in their sound. From around 200 hours on, they just get better and better and better. As far as bass response goes, although they are not as strong as a good subwoofer, they have very tunefull, accurate bass down to around the mid 40's in my room. In fact they do the low bass string (open "E"?) on a contra bass effortlessly. The bass really opens up with time....but you need to beat the hell out of these things and play them loud. Quiet won't break them in. I'd bet the Callisto's will have similar characteristics. Play em loud!
