My wife and I get an AirBNB in Carmel every year...same place.
It has a humble Bose stereo with a collection of CDs to choose from. Very charming. Obviously no consideration for acoustics in the octagonal living room the stereo resides in.
But the system sounds good enough that occasionally I take notice.
I think the lack of crossovers and the band pass subwoofer (also no crossover) create a very phase coherent presentation.
They don’t create issues they need to overcome. It’s smart. And good enough for most average folks.
We live in a different world where the potential to get better sound is always a priority.
