The system is in good/working condition.

NOTE:  The connectivity is listed as 'wired'; however, the sound signal for the back speakers is sent wirelessly to a receive which the back speakers are then wired into.

All components are included except the following

- Users manual (available at the manufacturer's web site)

- Calibration microphone.  I never calibrated the sound and it worked/sounded fine.  If you want the calibration microphone it is available from other ebay sellers.
