The response graph tells you you’re getting a big peak at ~45 Hz and a null at ~36 Hz with your sub in that location. You’ll probably see the same thing with your new sub at that location, but with better extension below 45 Hz.
The #2 location, is that a corner? You’d probably have much better luck putting the sub there. Normally I’m not of fond of “bass from the rear,” but I’ll take good-quality “bass from the rear” over poor-quality “bass up-front” any day.

Thanks again.
After about 10 tries trying to get whatever I messed up with REW settings corrected...I gave up and went back to version 4.0. Not sure what is up with me using 4.10 but I cannot get any measurements to work...I keep getting messages about level to high...then too low...then peak not being where it supposed to be...
Redid all the cal settings for version 4.0 and was able to get my measurements back.
The HSU is much bigger than the my current sub so putting it in the corner (#2) is probably what I will do...hopefully the response there is a tad better.
I am also getting some noticeable HUM/noise when I have the USB soundcard plugged into the input on the AVR. Gonna try to see if I can isolate what's causing it. I get it from both the SUB and the MAINs....And if I plug the USB soundcard output directly into the SUB I do not get the noise...so its definately something being introduced before the AVR output. My wiring is a rats nest near the AVR.
