Yes it could very well be the felt I am using. But I was thinking of what you said about taming
the back wave behind the driver. So tonight when I got back home I tried this:
Right Below the center hole of the driver I put this half circle piece of felt. It stops the high
frequency waves from bouncing straight back into the Driver. It's probably what causes it
to peak. And so far I think this might be the best sound I have gotten so far. The T1 is a
lot more musical to me with a wider range of music.
