B&W Nautilus 805 loudspeaker mounting

[ENCR]

Does anyone know how the woofer of the B&W Nautilus 805 (or perhaps other speakers in the Matrix series) is mounted on the baffle plate? Is the woofer screwed to the baffle, or perhaps clamped at the magnet assembly in the internal matrix structure, (which stiffens the case) with the basket merely making a compliant, airtight seal to the baffle? My interest concerns strategies to control the resonance of the loudspeaker unit on the baffle. When the front of the basket is screwed to the baffle there is usually a significant resonance in the range 150-250Hz.

My guess is they took the easy way out, at least with this one:

I think you are probably right. I found an image for the internal construction (attached), but only at poor resolution.

Hahaha, I had seen that one, but couldn't find a high res version. But on any of the 805's I did see the mounting screws were pretty obvious on the front.
