I'd think for the price of the JL subs you could find much better ones. Their -3db point is ~25 Hz, which is a bit lackluster for something that has an MSRP of $1100. At that price, you'd be better off with an SVS SB3000 if you want to stick with a sealed sub. Is that your decision, or their recommendation? Do you have size constraints for your subs?
Also, are you going to have front channel speakers for the TV in the bedroom? If not, I don't see the reason for in ceiling speakers
