Hello. Im currently running a 7.2.2 Bowers and Wilkins system with Kef Q50a as my front height speakers. I'm going to add rear heights and I cannot do in-ceiling. I would like to keep with the Bowers and Wilkins brand but outside of in-ceiling they only have the M1 speakers that are mountable. Has anyone used them as atmos/height speakers. Would they perform better than the Kef Q50a? The M1's frequency response is 64-23k Hz, while the Kef is 105-18.5k Hz. So as it appears the bowers should have a better frequency curve and do a better Job on the low end but I haven't been able find any information on the use of the Bowers and Wilkins M1's performance as height/atmos speakers. I like my kef but the bowers with the adjustable angles and more versatile mounting position make them a good option. Appreciate any input.
