Hey everyone I’m new to this forum, but I’m glad to be here and I’ll tell you why. I now own 4 sets of a/d/s speakers, one of which is L710a. Now I have found plenty of info on the L710, but really nothing at all about the L710. My question is there a difference between the two models, and if so what would that difference be. Any input would be greatly appreciated. Thanks
