Dipole patterns
A speaker with drivers on opposite sides is likely not dipolar, but rather bipolar. Examples include Mirage.Nor is a speaker with drivers on 45 degree angled baffles, in my opinion. Dweller's explanation is pretty good.Examples of speakers with di... 
Sub or Subs to mate with Sonus Faber Amati Homage
Try diagonal placement in the room if you haven't already done so. In square and nearly square rooms this can be of significant benefit. I would avoid using subwoofers if you can.Brian

Hi, I just spoke with a buddy who uses a pair of Krell MDA-300s to drive the woofer towers of his modified RS-1Bs. He uses a Dahlquist active crossover in lieu of the Infinity crossover for a couple of reasons, one that the latter is out of commis...
