I am hoping M60's will do an adequate job as fronts.
There is no question that the M60 can fill that space with sound given proper amplification, so I guess you are asking if you have enough amp. The answer to that depends on your objectives.
How loud do you like to listen? How far away from the speakers are you going to be when listening? Listening at reference levels (loud) in your kitchen (which I assume is the farthest point from the speakers) is going to take a lot more power than listening at the same volume 10' away from the speakers.
Given that the M80 is more sensitive than the M60 and draws a 4Ohm load, it will play
slightly louder than the M60.
Both the M60 and M80 are quite sensitive, so are good choices for limited power situations.
Fred,
The room distances are:
front of front speakers and DLP screen are 2' from front wall.
main listening pos. is 12' from fr. spkrs/screen.
(surrounds mtd directly to side of lis. pos. and 3' up)
Rear wall is 16' behind list. pos.
I am not concerned about dB levels in kitchen or dining area. I am only concerned with having the list. pos. (12'away) as enveloped as I am able, being limited to 90 wpc and M60 fronts w. M2 backs (I could go M22 backs, but Axiom rep said they would not add much and that the M2's would do fine in this room. ... any thoughts on this?). Side surrounds will be changed from dir. firing WG-150 in-walls (8" bass drvr)to QS8's.
M60's vs. M80's:
I was under the impression that asking the Denon 1909 90 wpc amp to drive a 4 0hm speaker was quite a stretch for this amp. If you know the 1909's specs and disagree, I'd love to hear your take.
ALSO having front mains drawing 4 ohm avg when all others (except VP150 at 6ohms) draw 8 ohm avg, would make the
front's dominate. I DO NOT want to go there again. I am coming from using huge 15" driver Klipsch Cornwall II's (owned for 26 years) with 100dB sensitivity always dominating my (M2 size) old (90db) center spkr. With all other surrounds @ 90dB sensitiv. as well.
