For those who have not seen Rowan Atkinson Live, here's a really funny one called "Guys After The Game"
The 'warm spots' in my speaker system are 100hz and 1000hz. It's weird how the room deadens at certain frq's.
Hmm.... a bit surprising results. My Audio Technica ESW9 didn't even manage to reach 14K, but the Sennheiser Momentums went over 15K. The AKG K-702, as expected, got up to over 17K though.
