Sub Phatty output

Hello everyone, long-time lurker, first time poster and have been obsessed with Moog products since I had a Prodigy back in the 1990’s. I was curious what people use as output for the Sub Phatty? I currently have one and am using an old 70’s Fender Twin Reverb and I know that it could blow that so what are some decently priced monitors/amps? Also what is a good keyboard stand to use for the SP?

My SubPhatty is connected to a mixer. And the mixer is connected to an active 18" subwoofer and two active studio monitors.
On stage, I will not use an amp, but the PA the rest of the band is using. When you got several synths, using an amp is not an option.
But I am aware, I might miss part of the special color and drive a real good amp like the Fender Twin Reverb adds to the sound.
