Room size for B&W 802D???

Is bass boom going to be a problem with B&W 802Ds in a 13' x 24' room with 9' ceilings?

The speakers are placed up in the dining room facing out into the living room. I can move them at up to 3' off the back wall but they will be no more than 2' off the side walls.

I have wall-to-wall carpeting, a heavy wool 8' x 10' area rug in front of the speakers...facing a leather couch.

I've been running 803S's with no problems.
