Magnepan DWM

The Magneplanar Bass Panel (DWM) is a dipole, thin-film, planar/magnetic bass panel. It is two bass drivers in one panel. Two "voice coil" grids drive one bass diaphragm. 

The Bass Panel is essentially a small section out of the 20.1 and 20.7 bass drivers. But, please don't call it a "subwoofer". Subwoofers are a separate category from woofers.

Subwoofers are intended for below 40 Hz and are known as "slow" and "muddy" when used above 40 Hz. Subwoofers can be adjusted higher than 40 Hz, but you will achieve better sound by using the Bass Panel to optimize the bass of your Maggies. The DWM Bass Panel has no problem integrating with a full-range Maggie because it is "all Maggie".

But, the Maggie Bass Panel affords far more than increasing bass/midbass output. It is common knowledge that multiple subwoofers can be used to fine-tune and smooth the bass. What is not common knowledge is this technique can be used up to approximately 200 Hz. 

Through trial-and-error, the position of mobile bass panels can smooth both phase and amplitude response for the preferred listening position. Often the ideal listening position for imaging is not the optimum position for the smoothest bass/midbass.

Standing waves can be trouble-some, creating peaks and dips in the bass response. The Maggie Bass Panel can help fine-tune any of our models, even our flagship 20.7s.
