Oh ok - the only way to connect the sub to the T9 is 'high level' (it's a 2.0 device). In which case you'll be controlling the volume of the speakers together with the sub and you'll have to fine-tune the sub with the volume knob on the sub. And for music this is the optimal setup anyway.Ok, I have an T9 Pro on the way and would like to use a sub with it and never owning a sub before I was wondering if I would have to adjust the volume of the sub as well as the T9 to match them up or would the T9 do it all….?…I understand the initial set up would take some tuning but after that would the T9 be the master variable?
If your preamp stage has a sub in (like an avr) then you can use that and fine tune it through that system.
