I have the KF92. It's a tiny little thing with only two 9" drivers in a 13" cube, but it really packs a punch and delivers some clean, deep bass. I would bet that this is similarly powerful for its size.

^^^Not a chance that little box with 6.5 drivers is hitting 11hz unless that’s the sound it makes as you drive over it with a truck^^^. More meaningless spec claims.

So, it is the equivalent of a 9.2" single driver. I would be interested in what their performance really looks like. I wonder if they will publish any detailed specifications and measurements.

Sure. At what level? Certainly not at the 105dB level on a separated line.

Looks similar to what Devaliet Phantom does with opposing drivers and a lot of watts.

102dB then if the +/- 3dB is believable ?
The linearity "+/- 3dB" doesn't predict this. Here's a real contribution:
I asked KEF for a more specific metric, the maximum anechoic SPL achievable at 20Hz, and they said 80dB. In-room that'll be a lot louder. I still think it's impressive, but much more believable for 2x 6.5-inch woofers. Besides, it all depends on what the bass limiting curves look like. Maybe it can get to 100dB at 30Hz, for example. We'll have to get measurements to see.

Hard to beatphysics. Can't imagine wanting such a bass module (hard to call it a sub).

FWIW, I did reach out to Kef to see if they would be able to loan me one for testing but - as I fully expected - they only have a few samples and those are already on loan. I did ask if I could be put on a waitlist but I don't expect anything to happen anytime soon... if ever. But, they at least didn't flat out say "no".
