big room speaker upgrade advice, Elac Adante AF_61?

 sorry for the typos 

have a room that is 27 x 30 feet with 12 foot ceilings, concrete floors and lots of glass. mostly listening to house/ electronic, funk and classic rock. and home theater using a Musical Fidelity M6500i { 500 wpc dual mono blocks} for 2 channel with 2 Rel S5’s , mostly source is sonos.

i damaged a crossover , tweeter and driver from my triangle antal 30th anniversary model and thinking i might need something larger for the room size . my budget is 7k for a pair of mains and a center would love to spend less { have a 9.2 set up for HT}

would the adantes AF-61 be a good choice for my amp, type of music and room size?  i heard them in a listening room bt with a very expensive amp , also read about the new KEF R11. would appreciate some advice in advance of some other recommendations that l should consider. my only other speakers have been dali ikon 8’s and  other triangles in smaller rooms
