I agree with this convential wisdom. Definitely let the sub amp handle 100% of the lowest frequencies. Given the M80's bass capabilities, however, do try 60Hz as well as 80Hz (only if your amp or receiver allows different settings for each channel -- 80Hz is what you'll need for the other speakers). Your ears will tell you whether a 60Hz setting for the M80s is better in your particular environment. Your M80s may love that 60-80 range!
