Infinity IRS Beta Room Requirements

I’m thinking about purchasing a pair of IRS Betas but am concerned about how much space they need for them to perform well so my purchase isn’t for nought. The dimensions of my room are 16’w x 17’d with 7.5’ ceilings. The one side of the room opens up to a space that is about 12’w x 10’d.

For comparison purposes, I currently own a pair of B&W 802 SII and Infinity Kappa 9. Both sound beautiful in their own ways, and are capable of very deep bass and don’t over power the room.

Thanks.
