Hmm question: did both quads sound good (or similar) in the larger room?
The room is of course so important.
I suspect your long narrow room may ‘load’ music energy better and especially so with the larger quads so they could ‘see’ above the table height etc.
But in the big room- especially opening to a kitchen, larger tall SL with 45 degree dispersion would definitely help bring that room to life. I am sure.
