FWIW...
I was at my Joseph Dealer's store yesterday dropping my Perspectives off, to be shipped for the graphene driver upgrade.
To my surprise they had the Pearls in the store. Hadn't seen them there before.
They were not playing but were set up closer to the back wall behind them than what I would think is ideal. I was told that the Pearls worked surprisingly well no matter where they placed them, and that they could even be placed closer to the back wall, as they were, without obvious bass bloat, vs some other tower speakers in the store which they have to pull out more.
Not what I would have expected, but that's what I was told.
