I agree w/ bdp24 above regarding the Clear Day Double Shotguns. I knew I was missing something on the top end but didn't realize how much until I got the Clear Day Shotguns installed. These opened up my system A LOT! Took maybe 30 seconds on the first song to hear the difference. Even the wife thought so, and she doesn't "listen" to music the way I do.
Used if you can find 'em, but worth it even at full price IMO.
