Magnepan Bass Panel Woofer DWM

Magneplanar bass panel. A unique addition to the Magnepan family. Can be used in various situations. Dipole, thin-film, planar / magnetic woofer.

Put a big speaker in a small room, too much bass. Put a small speaker in big room, too little bass. In general, it is true. There is no one-size-fits-all. In an ideal world, the bass diaphragm would be like an accordion door which could be pulled out and expanded to exactly fit the needs of your acoustical environment. Adding one or more of the Maggie Bass Panels accomplishes the same results as pulling out the bass section of your existing Maggie to a larger size---as if it were like an accordion.

Or think of it like the difference between a 12-inch and a 15-inch dynamic woofer. What does the extra 3 inch diameter of the larger woofer accomplish? Accoustically, the Maggie Bass panel is the same as the extra 3 inch diameter of cone woofer. It increase the total bass diaphragm area of your existing Magneplanars. Yes, the Bass Panel provides deeper bass by getting a "bigger bite on the air", but the Maggie Bass Panel is all about quality bass, not quantity. Getting a little deeper bass is nice, but getting the bass smooth and deep is better.

Most of the area of any full-range Maggie is devoted to bass reproduction. (In the case of the 20.7, 76% of the total radiating area is devoted to bass.) Audiophiles can be nostalgic about the 6-panel Magneplanar Tympanis of the 1970's and '80's. But, they could sound like a trombone in a telephone booth in a small room. The Magneplanar Bass Panel offers you the flexibility to add bass diaphragm area to fit the needs of your room. From the LRS to the 20.7, the Maggie Bass Panel can get the bass/midbass "just right".

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 20.7s.
