I also use a REL sub (T/7x) to supplement stand mount speakers driven by a tube amp. Sub speaker level inputs are high impedance and won’t load a tube amp output.
Tubes and Subwoofers
Are there any here that run tube integrateds/amps with subwoofers?
My setup, room, preferences incorporates a sub with sealed bookshelves to get that sense of space and bottom end.
My gear has preouts to connect the subwoofer, but am considering switching things up.
Does anyone use speaker level connections from their tube gear to a sub? Any downsides/concerns with impedance loads at the tube side with speaker level connections? Maybe it's gear specific?
TIA
