Hey guys I hit up the manufacturer too but figured I would ask here as well to try to figure this out.
I've had one HSU VTF-15h Mk2 since 2014 and love it, absolute beast. I just got another one last week and it seems to be much weaker than the original unit.
My room is about 12' wide x 24' long x 8' tall and I'm using about half of it for the HT viewing area.
AVR is a Yamaha RX-A3080, have two different subwoofer RCA cables.
Doing the sub crawl to find the 2 best spots in the room for placement (where the bass response is the flattest) with an SPL meter I found that basically the front left and rear right of the HT area respond the best so I have the subs in those 2 spots.
per HSU setup recommendation I have left the old sub with volume about 9 o'clock, EQ1 setting, Q 0.7, 0 degrees, 1 port open and YPAO usually sets its level to -7.0 or so, I usually raise it to -6.0 or -6.5 for preference. I set the new one the same.
With identical settings, I could tell that the new sub was not giving anywhere near similar output. I first tried swapping them (so swapping locations, cables and AVR outputs) and no surprise where the new one was, there was very low output. Running YPAO again after checking that both had identical settings (9 o'clock volume), it set the old sub to -10 dB and the new one to +7.0 dB.
A quick and dirty test to try to get the bass response in the seating area to seem even, I had to increase the volume knob on the new sub to about 1 o'clock.
Does this not seem like there's something wrong with the new sub?
