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?

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

I have read reviews of equipment that include xLr connectors and their circuit is single ended. I own a Graaf gm20 with balanced differential circuit topology. I am next going to purchase a preamplifier with balanced outputs. Audio GD is an option but of the two xLr outputs only one is in a balanced differential circuit the other is NOT. I have verified this with their representative. They can make one with both xlr’s set in the balanced differential circuit. This makes a difference to me because I can get the same preamplifier used, quicker, and at a discount possibly. The subs ar a pair of Martin Logan 1100x. I have read some articles stating that the real noise cancellation from xLr is only realized in balanced differential circuits. I have asked ML and their answer is that they are compatible. When I asked a second time rephrasing the question as in are the amps inside the subs balanced differential amplifiers the answer was that the question was already answered in the previous email, which… answer is not conclusive to me.

The point is I doubt very much that the ML 1100x would have a balanced differential amplifier but, if anybody knows for sure and wanted to confirm either or, that would be nice.

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.

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

Ohms sorry

I’d rather have choices. In this case because of noise that balanced circuits work better at eliminating. And, there is also the probability that all those apps are not that good. I don’t want to find myself with the constant need of trading equipment.
