At the request of my wife, I recently ordered a pair of Rhythmik L12s to ideally replace one Hsu VTF-2 Mk5. She wanted the white finish and smaller form factor. I figured what I'd lose in sub bass (from the larger ported design), I'd gain in more even room response.
That is not happening for me. I independently measured the best locations for the subs using REW. The response of 1 sub between my mains looks really good considering no EQ. As soon as I add in the second sub, I see a big null from 60-80hz. Doesn't seem to matter where I put it.
This is frustrating. Every resource I read talks about the advantage of multiple sub woofers, but my response is better with one. I understand that dual may be better for more positions in the room, but I don't want to sacrifice the even response at my listening position.
I've attached my measurements. 1 with front placed sub, 1 with the other on the left, and the last shows overlay between single sub measurement and both run together (60-80 null very apparent).
I also played with phase delay of the one sub, but it seemed to make no difference. I'm not sure if I'm missing something here, but disappointed so far. I ensured Audyssey is off, crossover to max, but set to full extension.
Any advice or explanation is welcome.
