LD Systems ICOA 12 PC

For this price these speakers are definately worth to purchase. Despite their weight amount of sound is amazing, also very good bass reproduction, in some cases can be used even without subwoofers. I can crank them up to full power without loss of quality in FLAT or SATELLITE mode, i didnt test them in fullrange mode. About 6 hours nonstop and no problems with overheating or anything else, quality of sound was stable (just one gig in room temperature) - volume was at 0Db, but on speakers max volume is +10Db, so there was a headroom. Sound is really loud, good kickbass and clean for this price range, some times it was uncomfortably loud indoors, but without drop in quality, actually these speakers exceeded my expectations.
Drawbacks: I really miss equaliser with more DSP control options in
them, in satellite mode it is necessary to reduce high
frequencies.
If crank up volume from +4 up to +10 db, there is coming
audible hiss from speakers, if no music is playing, but there is
no reasons to crank them up more than 0 Db, they are
LOUD, and therefore is a gain control.
