Have M22v2 on main floor with 175 sub. Marantz SR5000. Just for good sound on movies, TV, etc. with 50" plasma. Great little combination.

New HT in my soon to be finished basement. Overall room size is 24' x 21'; HT area will be approx. 15' x 15'. 65% HT and 35% music. Just picked up a Rotel 1075 5-channel amp. 120 wpc @ 8-ohms. I need to buy a pre/pro; probably go with another Marantz receiver. They have pre-outs. I understand the pre-pro effects sound more than amp. I do like the smooth Marantz sound with the M22s.

My question relates to the sound of the 60s vs. the 80s. My amp will have power to push either speaker so the 4-ohm of the 80s is not an issue. In a HT package, cost is really not an issue between the two. Can anyone tell me if there is a significant difference in the sound of the two speakers?
