Madisound (www.madisound.com) used to have some pretty slick 'generic' grills for a variety of drivers and some nice mounts for remote tweeters (Audax drivers) that would give very nice results if integrated properly. The folks at Madisound can be very helpful - you might call or email them. The solution is usually very clean and understated visually, with a bonus of being rebuildable (if he blows them again) and the potential of excellent sonics.
