Hello, looking for advice before I actually test this due to complexities involved in accessing speakers.

My main HT setup currently includes 2 M60, 1 VP150, 1 EP350, 2 QS4's + 2 Polk speakers for front Heights.

I have a setup in another room with 2 M22's and 1 VP100.

My question to you dear Axiomites is this...

If I were to switch the M60's to the M22's in my main HT setup, would there be any noticeable impact to sound?

What does this button do?
