Set of 8 wired surround speakers. They will work with any of Panasonic SC-BT303/300/203/200 blue-ray DVD systems. I have a BT300, but I'm using a newer Sony soundbar with remote subwoofer instead of these.
(2) tall columns
(2) small side left/right
(2) small back left/right
(1) center
(1) subwoofer
The rear L/R speakers hook up to a SH-FX70 wireless receiver (included) which has a corresponding plug-in transmitter module (included) for the main unit (not included). This remote unit cost $70 alone.
Note: these are all WIRED speakers. Each one has two wires terminating in proprietary plug(s) that fit into either the wireless receiver or the main unit. But you could probably retrofit them to anything.
NOTE: Picture shows the BT-303 unit w/ remote -- these are NOT included.
