In passing, the M80 floorstanders have useful output in a room to about 25 Hz. For the record, the only instruments with significant content below 30 Hz are the concert grand piano (28 Hz for all but one Austrian model with extra keys at 16 Hz); large pipe organ, 16 Hz, but the latter is very low level and the 2nd harmonic at 32 Hz is much stronger; and orchestral bass drum, depending on the diameter of the drum.
Yup, this is what I tried to say so really I only listen to pop/rock having a sub is useless if the M80's can do this. Which is why I want the M80's for music video or cd's.
