Impressive - but in this case I’m just want to swap out crossover plate and Uniq which are not that different - speaker size is remaining same so it seems on paper that no advanced speaker DYI knowledge is required. But I wonder if there is something I don’t know that would potentially be fatal here
@Daka,
i am quite sure that crossover for the old Uni-Q will not fit perfectly for the new Uni-Q meta chassis
the wrong crossover for the Uni-Q chassis can ruin the whole swap approach
that said the approach to activate the whole stuff with hypex plate amps and find a DIY fellow with measurement equipment is even less risky
question: where do you get the meta chassis, you buy a new R3 meta and have the old R11 non meta already or the old R11 as used speakers?
oops, checked the specs of the R3 Meta against the R11, it cannot work with the swap of the crossover for sure!
the R11 has four bass chassis, R3 Meta only one
the sensitivity of the Uni-Q mid-high range chassis is attenuated much more to work with only one bass chassis in the small R3 meta cabinet
R11 floor standing speakers are perfect for any music lover's setup, offering high-quality HiFi audio, rich bass, sound absorption and a near-complete lack of distortion.

sensitivity difference over all 4 dB, 86db R3 Meta, 90 dB R11 - again this will not work with the crossover swap!
the showstopper:
r3meta nominal impedance 4 ohms
r11 nominal impedance 8 ohms
=> no way the crossover swap can match
for sure you have to completely rebuild the bass crossover section and to remove the attenuation of the mid section and high section of the crossover for the coax
there is a good chance to assume that the Uni-Q chassis for the R11 has a greater sensitivity as the Uni-Q chassis for the R3
to sort this out you have to find somebody that owns an R11 Meta and is willing to open it anyway
KEF use for sure a modified high tech Uni-Q chassis with neodymium magnet motor in the reference series and the blade, hard to find pics of those
last recommendation, buy the r3 meta and use two subwoofers to get the better bass performance
here the DIY fantasy kicks in again, build the subs on your own as floor stands for the r3 meta, e.g with 2 side mounted sw chassis for each floor stand sub for impulse compensation
