There are some 7 and 8 inch coaxial speakers on the market, and they're at least usable(and at least one 15 inch but I haven't seen any reviews or measurements of it) - maybe Kef could use their expertise to attempt to mitigate the downsides.An 8 inch coaxial driver would not work. The woofer would interfere with the tweeter too a far greater degree than the 5 inch one. Better to set sights on the Ref 3, hopefully updated with the Meta treatment,.
Why would anyone want to mess with larger coax woofers? I predict LS60 will be 3 way, may be with a larger 8 inch woofer crossed at 300 Hz. A better R3, maybe with an active option, and a premium timber option.There are some 7 and 8 inch coaxial speakers on the market, and they're at least usable(and at least one 15 inch but I haven't seen any reviews or measurements of it) - maybe Kef could use their expertise to attempt to mitigate the downsides.

You want them to become B & W? Fuyeeooo say Uncle Rodger!Hopefully they’ll add 7” woven fiber midranges housed in spherical lexan enclosures and place a diamond tweeter on top.

Good point. Was thinking the dust cap of the 7" midrange could be unscrewed and replaced with a tweeter. Hot glue should hold it in.You want them to become B & W? Fuyeeooo say Uncle Rodger!
Both the measurements (especially of the Tannoy) don't look as good though as from the 4-5" state of the art mid-tweeter coaxes from KEF and Genelec, there is a reason KEF uses their larger drivers only on their entry series.Sure it would, and does. The Q900 coax is a fantastic driver. I had a desktop monitor built around the Q900 coax, and even if LS50 had grilles (naked drivers are aesthetically unacceptable to me) I would prefer them sonically to LS50. I posted some measurements of them here. I've had idle thoughts of recycling those drivers into a Dutch & Dutch style cardioid.
The Tannoy “Omnimagnet” 8” coaxes in the Revolution XT 8F as well as a number of their ceiling and indoor/outdoor speakers are also very good.

Like all Q series the driver has big surround and moves quite a lot; is never ideal when the driver acts as waveguide for the tweeter; also causes IMD. How audible is this? hard to tell, but I would prefer the R/Reference type of coaxial implementation.Presumably by now you've looked into the Q950's - any thoughts? Not much data I've found so far re: 8" Kef drivers, yours might actually be the first I've seen.
Hello Thewas,
