[QUOTE="VWBobby, post: 7357215, member: 624844"] [COLOR=Silver] Nope. Ocassionally I'll get a weird harmonic or 2 that will make a sharp buzz. I have the doors lined with eDead 45 and since its a '65 Bus, the windows slide sideways in channels. No window regulator or anything else to rattle around in the doors.

This will keep your mids in a band where you can throw a lot of power at them and not get too sloppy (playing wide range).
