the bass in the 33 is surprisingly non-crappy. it's no 5500 or anything, but it's far better than i know i expected.
i use 5000s as my rears, and i use 33s in my bedroom as the only speakers. i listen to the jazz stations off the satellite all the time and i think they sound quite nice.
i originally bought them to use as my rears in the den, but was concerned that they'd lack enough bass. after using them now for a few months in the bedroom i'm reconsidering installing them in the den (much better WAF) and moving the 5000s to the bedroom.
i have the omnimount wall mounts. i don't think the arm has enough clearance to be used as a ceiling mount (the speakers wouldn't be able to get vertical). i'd be stunned though if omnimount didn't have a similar ceiling-mountable version.
good luck.
doody.
