It depends on the rest of your system but Roon definitely does support subwoofer level control and, even, bass management. I have used it for stereo, 2.1, 5.1, 5.3....
What is the rest of your system and how is the sub connected?
Roon? does it offer subwoofer output volume control?
does Roon include this feature? Alternatively, does it offer a simple method of accomplishing this via EQ?
would like to upgrade my sub but not too many units offer this
I can't live without it after using it on the KEF app and now with SVS
very much hoping Bluesound will upgrade their software to include this
thanks in advance
