Yep,I agree 100%. I plugged my 166's and couldn't believe the change it made for the better. It's a little nerve racking making that first plunge with the x-acto knife though. Not so bad once you actually do one. I'm also using the rat shack super tweeters coming in around 9k and they add a very nice sparkle to the top end. Don't really need em, but I like it better with them than without.
