I finally got around to moving the HSU VTF-15H into my right front corner.
But before doing so, I made a 1:1 sized reproduction of the back panel graphic. I knew I'd have to reach over the top from time to time and make some adjustments. The graphic allows me to feel my way around and make some quick adjustments.
I've included the printable graphic for anyone else who has the same sub. I just set it on the top of the back of the sub.


First impressions of this sub are really good. It does dig deep. There are lots of settings that you can tweak to vary your results. And the balance with the two subs in each front corner seems to work good. There's a note in the beginning of Tron that I never even new existed!
I've found my M&K 350 sub can also go very deep when you take it out of THX mode settings. One thing I've noticed with both of these subs digging so low is that my sound proofing may have needed more. If I go to near reference levels, the floor above does vibrate.
Perhaps another layer of drywall may have solved the problem...but not sure. It's still magical that I can listen at the levels I can without disturbing the family upstairs.
I've been tweaking the speakers in the room as well and tinkering with some of the Onkyo settings based on THX settings to see how things sound. Chris from M&K was nice enough to spend two hours with me on the phone last week going over everything within the Onkyo to prep me for using REW.
I've angled my front LCR's down just a bit to target the primary listening position and verified that the wides are also at the same level as the fronts. I moved my LR speakers out to the very edge of the inside of the projection screen.
I also configured my M&K SS-150's for Heights and Wides to be in Direct Radiating mode instead of Tripole mode. The sound in the room is continually improving.
My next thing I'd like to do is get some insulation in at least the bottom half of all the speaker columns to prevent any resonance that may be happening. I think I've asked this before and not got an answer, but is there any benefit using OC703 instead of fluffy insulation in the speaker columns?
