the reason i deleted my post is upon re-reading the original post i realized i was not answering the question he was asking. i had not taken the time to read it all the way. obviously i take my bass performance very seriously.
thank you for the kind words about my system.
i have not measured my bass performance in my 2 channel room. those are the published specs of my Evolution Acoustic MM7 twin tower speakers (my speaker designer and builder has spent a couple of days in my room setting my speakers up).

with 2 channel there is a music focus so there is nothing useful to hear at 7hz or 3hz. the reason those frequencies are relevant is it does allow for lots of headroom and linearity in the 10hz-20hz region which is musically useful. suffice it to say that the bass performance far exceeds anything music can throw at it. my purpose designed and built room is optimized for bass performance; there is sufficient room for the music to breathe and strong room boundaries to control good bass extension.
and to be honest, the fact that my Evolution Acoustics MM7’s have 4 11" woofers per side is more significant to the bass performance than the bass towers. the music and the bass lives in the mid-bass, not the deep bass. the deep bass is sexy to talk about but for music it’s not the main thing. more the cherry on top. but great systems get the mid bass absolutely perfect. and you are transported.
mikelavigne - That’s a very nice system, I’m envious. Why did you delete your post? I’d like to learn more, how do you know it’s -3dB at 7Hz. and -6dB at 3Hz., was that correct?
