Subwoofer xLr connection

It has to be a balanced xover with equalized to preserve the balanced circuit. I do not have the preamp yet but thinking of an Audio GD with both xLr balanced outputs. The other one going to a Graaf GM20 fully balanced power amp.

Wouldn’t it be nice if a preamp with bass management fully balanced unit existed, in stereo plus 2 subwoofer outputs.

The speakers are Cain and Cain single horn Ben with 8 inches drivers by Fostex, 8 inch constant or minimum impedance

Ohms sorry

The bottom processor link below may have preamp capabilities. You would have to contact them directly to verify.

Links one and two are to balanced analogue crossovers and links three and four are to crossovers with DSP processing.
