I owned kg4 before and liked them very much. They are very efficient, play loud, have good extended bass and easy to place. They look good too with real wood vener. However they are somewhat large and heavy so shipping might be expensive.

For second system looking at Infinity rs 5001 with emit tweeter, klipsch kg 4, Boston acoustic t 930 II, and entry level polk monitor/sds series from 80s, and JBL L-3 ...any clear cut winners?
