What's the budget? At the cheap end, Paradigm Atom Monitors. For about $300, great bass and good treble dispersion. Also Dali's have some in the under $1k range that are surprisingly good. At the higher end, ATC's or the new small Spendors. Need a little grunt to push them (50 WPC minimum). The LS 50's left me cold, but that's just personal preferance. A pricey used option are the JBL L92's. Nice dome tweeter and a 10" woofer. Ported and very efficient. Saw some for around $600 with new caps and refoamed woofers.
