whilst trying rotel 981 driving cdm1nts fronts+3802 direct mode ,i out of curriosity swopped bw 600s3 normally used as surrounds ,to the front, and tried a couple of cds, quite suprised to find that there was not a "great differance between the cdms and 600s3, the cdms had richer bass/midrange but i did not find it was day and night though,as speakers are from the same company i assume they have simular tonal traits etc, your comments please, thanks all
Well the tweeter units have a very similar timbre and they contribute to the bulk of the "character" of the sound in a multi-way system. The 600s aren't full range so that would go some way towards explaining the lack of warmth in the bass/mid-bass dept. Having said that, they can sound pretty "full" if pushed back against a wall. Did you listen with a sub hooked up? If you did, then that would have covered up the discrepancy in the lower ranges to a certain extent. More so if using a high-level connection. MuFu.
P.S. The fact that you choose products from different ranges in order to form your system (regardless of whether the decision was due to financial circumstances etc) is testament to the fact that the differences really aren't that great.
