The integrated speakers are three 40W CB-SP1200XT speakers. The subwoofer is the DHT-SW1.
The speakers are all placed in the row below the TV and the subwoofer / receiver is inside the middle column. That leaves you four completely empty shelves for all your stereo equipment.
Pretty cool until you blow one of the speakers.
No word on price or date of availability.
