Description

Upstairs system: Horning Eufrodites singing wonderfully with the Whammerdyne 2a3. No crossover network in these speakers. 

Downstairs: Magnepan 3.6r's are actively bi-amped via the Marchand XM44 using Coda S5.5 on the high channels, and Coda 15.5+ on the bass panels. 

The 3.6r's internal crossover network (from midrange to ribbon tweeters) has been updated with Sonicaps and Solen aircore inductors using stock values, and completely rewired with Neotech solid core OCC wire direct soldered to all drivers and Cardas binding posts. Mye stands add rigiidity and Gaia II carpet spiked feet finish absorb vibrations and provide improvements in clarity.

Your successful use of a large dipole planar loudspeaker in a narrow (11') room proves the notion that dipole speakers can be placed very close to side walls with no penalty paid in sound quality. Dipole speakers create front and rear wavefronts that are opposite in polarity; when those opposite polarity wavefronts meet on either side of the planar panel, the result is a null (+180 plus -180 = 0) on each side.

What dipole planars DO require though is "enough" distance between them and the wall behind them. 3' is often cited as sufficient, but imo 5' is more like it. Your room's 19' length is ideal for Maggies and other planar dipoles. Nice!
