Customizing it on your preference. I did play on it and created just band pass if both use. If you want to shave bass or cut high frequency. If this hi and lo on subwoofer section it would have much better use for me. I like overlapping by few hertz to ensure no dip.

A couple of my non-plus (i.e. OG) Pros just got this build version, 4.8.724036
Strangely, when clicking on the version number, before installing, it merely showed a blank screen, no release details.
