Thanks all.

I did not know that volume and SPL were inseparable. You're probably right then, I may just be setting my sub a bit too high. It doesn't help that on many recordings the bass is at absurdly high levels. I can re-evaluate the crossover then, too.

It's not that the soundstage is bad with the M22s, I was just wondering if moving to a more expensive model would increase it, that's all. I figured that extra money had to go to something smile I was just curious if it was more than bass extension.

Thanks again.
