I am wondering how much difference there is in the bass response between the m50's, 60's and 80's. Particularly betweent the M60 and M80. I read a review that claimed there was a pronounced difference. Its hard to imagine that 2 inches in height can add that much to a speaker. Especially when the driver compliment is the same. I'd like to get the M80's for the bass response, but I am concerned that the midrange and tweeter output on that model may be overpowering in a smaller room.
The last time I purchased stereo equipment in the early 1980's designers were still using 12" woofers for top of the line speakers. Now it seems 6.5" drivers are the norm. But then everyone says you need a subwoofer. Hmmmm.
