when I look at these I can't help but think "horn"
it like all they're doing is trying to introduce some sort of quasi-infinite baffle system, possibly with a passive radiator (can't tell) and possibly just with the open port on the bottom (oh god, ported, must be the DEVIL and we should BURN IT DOWN because it actually lets the sound TOUCH something like AIR

)
these honestly look "smart", and probably sound great (I'd love to hear them as well)
as far as B&W trying to "minimize all resonation", they have their own method of doing what Boenicke has done, from the B&W website:
Quote:
The sound of silence. Not all sound generated by speaker drive units is good sound. The kind that emerges from the back of a working driver, into a conventional box cabinet, can bounce around and make a mess of the good sound coming out of the front. B&W’s trailblazing Nautilus™ speaker found a way around boxes. Tapering tubes filled with absorbent wadding soaked up the wayward sound energy and reduced resonances to an insignificant minimum.
Nautilus™ Tapering Tubes are fitted to nearly all B&W speakers, even when they’re not visible to the eye. Sound is channelled through a hollow pole magnet, away from the diaphragm, and disappears into the tail.. So all the sound you hear is good sound. |
in other words, instead of playing around with horns, reflections, etc from the back of the driver, they have the "tubes"
neither is "wrong", just very different engineering approaches
