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

Rel's prefered connection is via the hi level, speaker connection, for example. This is the way I have mine hooked up. Workes very well and no issue if its a tube amp. you also do not need to use the same taps as the speakers are on if thats a concern.

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.

You should have no problem proceeding with your plan. I have small pair of REL's connected to a small SET with great results.

I used the outputs of my tube amps to drive the high level input of my active subs for quite a while without issue at all.  The sub's amp is completely separate.
