Hello everyone! I'm hoping to get some direction here, thanks for any constructive advise!
My Current Setup:
LP>Tube Phono Pre-Amp>Tube Amp(no line level outputs)> Stereo Speakers
Goal:
Stop stressing out the tube amp with lower frequencies (less than ~100HZ) and send them to a self-powered subwoofer letting the tubes focus on mids and highs.
My First Stupid Plan:
Split the signal from the phono preamp, install two 100hz FMODS on one side of the split to stop the bass from getting to the amp, the other side of the split gets sent to the sub. Why was it stupid? No synchronized volume control between the sub and the main speakers... fail.
My New Plan:
Either implement a miniDSP 2x4 HD or attempt original split/FMOD approach while adding a potentiometer to the phono-preamp stage to act as a master volume control. (the main power amp volume will be set static to ~75 of max volume)
So on to the questions!

- What do you think of my new plan? If you have a better idea i'm all ears.
- If you think my plan seems like a decent one, I need some direction as to modal and resistance range potentiometer recommendations. The Preamp is a YAQIN MS23B, and outputs .5v Thanks Again!
