I was listening to my system (as I do nearly everyday now) God-smacked about how this system can make anything one throws at it sound so frickin good. Finally my wife stopped reminiscing about the
LS6's...

Was letting Qobuz play some random music and along came a song from Soundgarden - Superunknown album - forgot the name of the song. the bass notes came in and was jaw dropping. The bass impact was pretty insane and it left another impression on me. Then a thought occurred to me (it happens sometimes), what if I took the SVS Ultra 16 subwoofer sitting in my HT setup and installed it, temporarily, with my 2 channel X3 system? I lighten the load on the X3 subs slightly and let the SVS take us down to twenty Hz? It doesn't cost anything (well not yet anyway...).
This I found may not be possible unless someone here can help.
My integrated does not have any audio outputs. However, the plate amps on the back of the X3 do but of course only speaker cables are attached. I don't know who the plate amp vendor is so I don't know what is possible with only that analog signal, probably nothing.
Thoughts?
