I’ve been running the MMG’s bi-amped for a few weeks with an inexpensive Pyle active crossover. It works as advertised but has limited x-over point selection. The sound is so very much improved. The treble and especially the midrange/vocal clarity are wonderful. Given these results I decided to ‘do it right’ using a 2x4 Mini-DSP. I have 2 questions on setting up the MMG’s for bi-amp 1)Recommended crossover points and slopes for the Mini-DSP 2)How to ensure the mid/bass and tweeter panels are being driven in-phase? The wiring strip with 4 connections: I assume it is +-+- The sound is good as-is though I have not tried reversing it… I’m sure both have been covered before, but could not find them easily. Any other tips & tricks would be appreciated! Bass duties are being handled by an active subwoofer, currently crossed over at 50hz. Once the MMG’s are set up I will do some serious a/b comparisons with the 1.7’s. For those who are interested, a low-end Onkyo receiver is handling all 4 channels of amplification. The receiver is not rated for the load, and initially ran quite warm. As I have little investment in this piece of gear, I added a small 120v industrial fan to the heat sink section. The amp section now stays quite cool. Long-term plans include dedicated stereo amps for this setup. |

Hint. You should think polar response here. Horizontal polar response, to be more specific. Cheers, Dave. |
