B&W (Bowers & Wilkins) 802 Matrix III Speakers w/ external Northcreek Crossovers & Grilles

For sale is a pair of B&W 802 Matrix III floorstanding speakers in a black finish sold with external Northcreek crossovers and all of their grilles (4 grilles total). This is an excellent pair of speakers with great sound quality. These crossovers really make a huge difference in the sound quality and are a major upgrade over the stock crossovers. They can stand on their end behind the speakers so they don't take up as much room.  
They have been tested and confirmed to be in perfect working condition.  Cosmetically, they are in very good condition with only some minor markings on the tops. See photos for details. 
The crossovers need to be Bi-Wired from your amp, and then there are proprietary connections to the speaker from the cross over. The cross overs can be up to 3ft away from the speakers and can be laid flat on the ground or they can stand up directly behind the speakers. See photos for details.
