Dont know if we’re looking at the same data but FR is bad F3 127Hz, non flat and changes at different angles, Harmonic distortion bad, dispersion bad, dynamic range starts to falls apart at 96db/1m - while it can be argued for height speaker you dont need that much perhaps, I think these are bad choice for surround. Obviously this might slightly change with R8 meta - FR and directivity might be somewhat better but neither distortion nor dynamic range will. Can’t believe R8a costs 1400 in US. Wowzy.Since we love data here at ASR, this is a fairly good review of the R8a: https://www.erinsaudiocorner.com/loudspeakers/kef_r8a/
The summary for those who don't want to click:
what about creating box for in walls and hanging them ? Still too big? even like a ceiling speaker - ci200rr boxed or going with something like Arendal 1961 height speakers. Only slightly bigger and you can have wall/ceiling bracket with them. Very good quality and performance.I can't use wall-in speakers in my den, and the only other option would be to ceiling mount a LS50 or R3. I'll be looking at an expensive divorce.
