I have not used an Spl meter However I had turned off my sub just hear what the M22's could do on their own. Then turned my sub back on and readjusted its output to my liking. I feel I have achieved a better balance in sound when watching movies this way. A little more sound from left and right than before. And as others have noted WAF is much higher now than before. So it really is a subjective thing. Looks like I opened another can of worms. Almost to the extent of speaker cables. But that's a few other threads.
