Seeking help with subwoofer choice as I am interested in a Rythmik 12, or Rel Tx7 or 9. Right now my system is as follows Audiolab 6000 CDT digital to Schitt Bifrost xlr to Schitt Freya+ xlr to Schitt Lokius xlr to Cherry STM amp running Tekton Lore Be floorstanders. The issue is that My amp have has a xlr input only which seems to be a no go with Ryrhmik. I lean toward Rythmik, any advice would be appreciated.
