Sure, you could install 11 speakers all around your living room pointed at your favorite chair for the ultimate audio experience. But if you're only worried about that one chair, why spread those speakers out? Just stick 'em in the chair and let anyone else watching with you wear headphones.
The BodySound chair is a $6,000 chair loaded up with seven built-in speakers. It's built for a full-body audio experience, and you can be sure you're always smack dab in the middle of the sweet spot. Sure, it's a little selfish, but hell, I'm sure you could get two if you really wanted to share the audio love.
