Anyone Know about Entechs Propietary 4 Pin to XLR?

Hi there, I just scored and got a pair of Wilson Cubs sitting on top of a pair of Entech L-F20 Subwoofers.

The entech use a propietary connection which has XLR on the connection to the crossover box and a 4 Pin Connector to got the Sub Amp.

Does anyone make these 4 pin adapters? Can I make my own custom cables to improve performance?

I assume the cable is wired with 2 leads and 2 returns for the 4 pins?

Any help is awesome as it appears if the cables go so do the subs
