Bowers & Wilkins B&W ASW4000 Active Subwoofer Massive 15" Sub 450W

Impressive 15" 450 Watt subwoofer in cherry finish.  A perfect match for you 800 series speakers. A few scratches here and there but perfect working condition. 

Pickup in Ridgewood, NJ or NYC.  Will deliver 20 miles of 07450 but would need help unloading as this monster weighs 75kg. 

Also willing to strap it to a pallet but you'd have to arrange pickup. 

Thanks.
