Used in a Smoke free environment, comes with a remote and power cable. It is built like a tank, and looks and sounds every bit of worth at its retail price of $2500, it's a steal for my asking price. These rarely come up for sale and this is the cheapest one currently on the market.


Buyer is responsible for shipping. I still have the factory box with all the custom padding to allow for safe shipment.
