Pairing Planar Speakers With A Subwoofer (Eminent Technology)

I have paired them with  a pair of Vandersteen 2Wq subwoofers. Superb, seamless and I consider it a 3-in-1 upgrade as the unique feedforward design of the 2Wq's frees up more juice for these power hungry speakers, which benefit also by only having to play from 80hz upward- less juice required. My amps don't work as hard.
My brother walked into the house and commented, without entering my listening room, how effortless my hi-fi sounded.

@mitch4t , your room is stunning but dsp would, I imagine, be a must with all that glass and no room treatment. I find JRiver's onboard options very useful- even without any room correction software (just playing Alan Parsons' test tones and sweeps over and over and adjusting certain frequencies with varying Q worked well to tame room modes), but that only applies to digital playback I guess.
