Subwoofer xLr connection

Good question. They’re in the boxes but the manual says balanced xLr. It is not discontinued Dynamo 1100x the additional x is my mistake.

Now, the manual says that input does not work with the crossover its management being by the pre processor or receiver. So I would need extra bass management because I do not know of a preamplifier with bass management. Any suggestions?

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
