Seemingly I only stumbled across this forum in the last couple of weeks, and I'm pleased to see so much QSC lovin' about.
While I don't have a surround set-up (well there's 20 year old Yamaha Pro Logic floating about somewhere) nor a Blu-ray player, I do appreciate a powerful sound system with plenty of extended fidelity.
I also so happen to have a pair of QSC K10 top boxes and a KW181 sub, and I wholeheartedly agree that the quality of the output of these things is extraordinary. While I originally purchased this rig for small front of house duties and foldback for my electronic drums and synth bits and pieces, I was startled at just how well these perform at moderate and low levels also for music playback in the home too. Just so effortless and projects so well from afar, whereas regular loudspeakers tend to lose their shine as one steps back (dome tweeters overtaken by room reflections, perhaps?).
BUT. there's one thing I just couldn't accept with these commercial sound-reinforcement speakers in a home theatre role... and that's the cooling fans in the back of each box.
How do you deal with that? In a dialogue-laden movie, away from all the high SPL effects and music, I think the background whir of the fans would drive me crazy! Thoughts on this?
Also curious peoples thoughts on boxes such as the QSC KW181 subwoofer....Transducer: 18" cone transducer
Frequency Response (-6 dB): 38 Hz - 124 Hz
Frequency Range (-10 dB): 34 Hz - 143 Hz
Maximum SPL: 135 dB peak
Amplifiers Power Output: 1000 W Class D continuous (2000 W peak)
So startling output where it counts in the 40-60Hz region, and will absolute shake the windows in a domestic setting, but rather lacklustre in the true sub-sonic 20-35Hz preferred zone of the die hard home theatre buff.
