Please, please tell me that in this wonderful place you have, you've planned for a dedicated audio or A/V room. If not, you can buy the best speakers in the world, and it won't make a damned bit of difference compared to spending $140 on a pair of Bluetooth speakers. The room, and your position within it, is 90% of the experience. With the way your room is jigged, you are hosed!
