I listened to the Sonus Faber Cremora at a dealer’s showroom. It sounded beautiful as long as the dealer played his choice of tunes. But, when I asked him to play some rock music (Green River -CCR) boy did they crack and pop, the dealer immediately lowered the volume.
So, I say if won’t play what you like at the dealers show room do not think it will behave differently in your home.
But more specific to your 3-year question, yes, the room size does affect the bass quality and amount.
