RE: Subs are sub optimal with magenpans!

Posted by josh358 on February 23, 2017 at 20:40:44:
One way to avoid it would be to put the sub in line with the Maggies, which is generally pretty close to what you want to do anyway to keep them in phase. The sub is omnidirectional so its direct radiation will apply equal pressure to both sides of the diaphragm, meaning there will be no net effect.

Another way to minimize the effect is to keep the subs away from the Maggies to reduce the levels at the planar diaphragms a bit.

Finally, if you use a low level crossover, the Maggie's woofer will be damped electrically in the sub's range by the amplifier. Electrical damping is very effective at preventing unwanted motion in a conventional dynamic woofer, but I don't know how effective it is in the intentionally underdamped and resonant (for dipole equalization) planar woofer panels.
