Cupped hands effect produces sound like when you cup your hands around your mouth to focus your voice....like a megaphone used by a cheerleader. The room I'm listening in is 15' x 35' with the speakers placed 5' out from the 15' wall and 30" in from the side walls. The listening position is 9' from the speakers. The room has a sloping ceiling that rises from 8' at the speaker end to 16' at the opposite end. My cables are pretty short with the ICs being 1.5 meters and the speaker cables only 4 feet long. Acoustic treatment has yielded only marginal improvements, but with a room that big, it could take considerably more than I have. Thanks for your comments so far!
What causes "cupped hands"?
I've been dealing with this puzzling phenomenon for several months. I can't seem to rid my system of the "cupped hands" or megaphone effect. Acoustic treatments seem to help but haven't diminished it to an acceptable point. I've been told that cables can cause it but haven't been able to confirm this. The system consists of:
Mark Levinson 390S CD Player
Antique Sound Lab KMP-60 Fox DT Amps
Aerial Acoustics 7B Speakers
1.5 Meter ZCable LIVE v4 Interconnects
4' ZCable PASSION v3 Speaker Cables
Any ideas?
