These were hand-me-downs and already cutout for larger tweets. ••• More options Share P Pan Member Joined 2002 2002-12-30 8:31 pm #7 2002-12-30 8:31 pm #7 BAM It´s the tweeter response meeting the low fr. noise in the room. /Peter ••• More options Share Show hidden low quality content Status This old topic is closed.
