My wife and I purchased the Definitive Technology - Procinema 600 5.1-channel Home Theater Speaker System from Best Buy about a month ago. It is hooked up to a Denon 4k receiver that goes to our 4k TV, iPod, blue ray, and ps4. The speaker set was impressive in the store but even better at home. It is in our 900sq foot living room and the sound is truly stunning. The sub woofer really puts out. So much so that we had to Velcro is it to our wood floor to keep it from walking across the floor during heavy bass music or movies with explosions. There speakers perform like the crazy priced but are much easier on the wallet.
