@kennyc yeah you're right it's costly but many modern homes don't allow much wiggle room for this, not without damaging the overall value of the home. Many times there are staircases or other obstacles or it's already an open concept to begin with so you're just creating new problems. I agree there are many options if you want to do ALOT of work and spend a ton of money.
It's just a rant about a trend of "weird" living rooms that offer little options other than just a tv - often only above a fireplace. I know they're not thinking about my rig when they design a house, but it's almost impossible in 'many' of todays designs.
