RE: Note about subwoofers with balanced BTL amp

Posted by AbeCollins on May 6, 2022 at 18:34:33:

Apparently it does affect other than REL subs but only when using speaker output terminals from some Class D power amps [including Wyred4Sound]. Less of an issue with a single stereo D amp, more complex connections when using a pair of Class D monoblocks.

REL documentation has several setup examples. I -think- it has to do with special grounding considerations between sub and Class D amps. If you're curious checkout the documentation for any REL T/5x T/7x or T/9x [and possibly others].

But you're not affected if you're running line level connections. The only reason I even know about this is because I was looking into REL, SVS, and Rythmik Subs
