Axiom Home Page Forums General Discussion Home Theater Which speakers for "height channel"?

I am considering upgrading my old Onkyo TX-NR905 7.1 channel receiver, to a 9.2 capable AVR.

I currently have, what would equate to the Epic Grand Master 350 in a 7.1 channel configuration.

I am considering upgrading my main fronts to a pair of either M50's or M60's at some point, and was wondering if my current M22's would suffice for use as height channel, or should I stick with my M22's, and considering either another set of QS8s (mounted up on my front wall) or M3s for height channel?

Has anyone adopted the multi-polar QS series speakers for height channel? I would think that they might do well, to help open up the height sound-field, and could sound pretty sweet.

Any advice would be great.

Thanks,
Spence
