there are such DSP devices for home systems. in fact they are built in on many home theater A/V receivers. and they can do some amazing things. Yamaha makes a line of sound bars that use DSP to create "virtual" surround speakers using room reflections and phased array techniques. when our repair shop went through Yamaha training, we set one up and let it go through it's "learning" routine. if you were anywhere in the center area of the room, the effect was very convincing. all there was in the room was the sound bar and subwoofer at the front of the room, but you could hear sounds from the back corners of the room as if there actually were speakers there. Denon receivers have Tom Holman's Audyessy automatic room EQ system in their DSP, and it works quite well.
