Does anyone make a preamp with a subwoofer output?

Many active subs have high and low level inputs, as well as a gain knob and frequency rolloff settings, which gives you plenty of flexibility.  If your sub has hi-level inputs, you can run it from the speaker outputs of your amp.  I actually prefer the way my sub sounds driven from the amp vs driven from the preamp line level outputs.

knotscott,


You are correct, I can adjust the slope and output on the subwoofer. I’m looking to be able to adjust the slope on my speakers. My speakers are Acoustat Model X’s and their design (three wire) I can’t run high level inputs. That’s why I’m asking about if there are any two channel preamps that can do what my HT receiver can do.

My Topping pre90 has RCA and XLR outputs. I run a KEF KC62 sub with the RCA outputs. The XLR’s go to Benchmark AHB2 monos. The Topping pre90 is a very neutral preamp. My Benchmark HPA4 preamp which the Topping replaced also has the same RCA + XLR output capability.
