Since we are on the subject of mid-bass slam, chest punch or whatever one wishes to call it, the one thing that makes it hard for many of us to experience it is the volume level required for people to start feeling it. I can easily achieve chest slam in my room but I just don't like listening at the levels it takes for it to hit me. And while the Crowsons do a great job of creating TR, they can't reproduce chest slam. So it's an elusive target.
Several years ago, VerticalScope took over AVS again, or changed formats, and a number of older AVS links were lost. Among them was a link to a more extensive study than the one that Audioholics did. I had first read about the importance of the 63Hz frequency, for most people, in an older AVS discussion which involved JJ Johnson, Todd Welti, and Earl Geddes. And, I believe that Dr Welti, cited and linked that study. Later, when I was writing the Guide, I tried to find the link again and couldn't.
I can tell you, though, that at least two submakers that I know of (SVS and Rythmik) offer pre-programmed PEQ (about a 3db boost I think) at 63Hz. I believe the SVS PEQ goes back to when Tom was still at SVS. The Audioholics article also mentions that frequency:
"One precise way to easily bump up the ‘feeling’ of your bass is to boost certain narrow bands in the bass region instead of the entire frequency range. As was noted in our testing, 50-63 Hz seemed to carry a very potent effect on the chest region, so giving that frequency range a boost may give your system an extra kick."
I seem to be pretty susceptible to chest punch, even at moderate volume levels, but apparently that varies among individuals. If I wanted to get more chest punch, and didn't want to increase my volume, or add an MBM in order to do it, I would experiment with adding about a 3db or 4db boost in the approximately 60-65Hz range. Anyone who already has a miniDSP for BEQ could easily do that.
It might take some experimentation to find just the right amount of boost, at just the right frequency, and even then chest punch is still dependent on percussive mid-bass sounds in the program. But, I'll bet that you could enhance your chest punch, Hop, if you wanted to play with that. Goodness knows, you have headroom to spare with your TV36 iPal's.
