Nothing could be simpler. Or more impressive. The PT7031 replaces a traditional A/V receiver and separate speakers with one, beautiful cabinet that sits on any flat surface or mounts directly to the wall beneath your flat-screen TV. But don’t let the simplicity fool you. This is true Dolby® and DTS® multichannel surround sound—made possible by NXT Digital flat-panel technology that reflects sound from your side walls to the back of the room to completely immerse you in the theater experience.
