Yeah, but when they put it into a packaged 2.1 set with the Mini-Maggies, it seems like it -should- be a fully capable subwoofer, not strictly a mid/low driver. It's fine as-is I just didn't realize I was over-driving the lows, and it doesn't seem to be a problem driving it unless the volume is too high for it to handle those low notes without the 'slap'.

It's just good to know that the panel probably isn't damaged in some way. I bought them used but shipped in original packaging. Magnepan did something really strange with the shipping box for the 3 speakers. The DWM panel isn't very well protected because it's not in the center of the box, it's on one side of the box making the weight distribution lopsided, and there isn't any protection along two corners of the box which the DWM sits right inside of. Needless to say the package was dropped onto the edge of the box, and the DWM panel took a blow without anything crushable protecting it. There's no visible damage to the panel but the issue with the 'barking' had me concerned that something was amiss internally.

I suspect lots of the DWM units may have gotten damaged in shipping if sent with this packaging method, hopefully Magnepan has changed it.

In Magnepan's words:

" 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. "

When the DWM ships by itself the packing is okay.

The Mini Maggie spec says 40-40KHz. The DWM spec says 40-200Hz. In practical terms none of these numbers are true. The DWM will play down to 40Hz but usable bass is only down to 50-60Hz, with the caveat as you found that they will bark if fed <40Hz at high amplitude. But the DWM does play quite a bit above 200 ... actually 300. The ribbon tweeters will play to 20KHz (not that most of us would hears that) and specing 40KHz is irrelevant hyperbole.

The other misunderstanding of the DWM is that there is mention of using them to augment larger Maggies. This incorrectly implies that they will extend the bass lower. This is impossible and it does not happen. What they do very well, is augment the bass in their operating range. And more significantly - lucky for me - they can be strategically placed to fill in resonance cancellations in the 70-180Hz range.
