I found this article timely for me as I have 2 subs and have recently experimented with running stereo bass.

Anyone have experience running 2 subs in a stereo vs mono configuration?
Disclaimer: Subjective discussion, take with as any gains of salt as needed.
After I got the Topping DX7PRO, I tried using it as a pre-amp, with the RCAs to my subs, and XLRs to my Hypex DIY amp. Bass was noticeably different - much less bass impact than previous setup. Even adjusting the sub levels did not help enough. Thinking the issue must be the 2v vs 4v output level mismatch between the XLR and RCA outputs, I got a small in-line adjustable line level gain amp (up to +12db), and this helped a little, but bass still seemed lacking. (Rest of freq spectrum was fantastically detailed, btw)
Hooking back in my previous integrated amp to be used as a pre-amp, and splitting the sub out RCAs of the integrated (back to mono bass), the bass was much more prevelant - smoother, more impactful.
I realize there are a lot of variables such as room acoustics, but my experience here is that there was a benefit to the mono bass - the subs working in tandem provided a much more uniform and powerful bass response vs each fed a separate L/R channel signal in the same locations.
Curious as to others who have compared mono and stereo sub signals in their setups? What were your experiences?
