REL Stentor MK III Black

One AMAZING sounding (ultra-deep bass that you feel with the music) Rel Stentor - MK III subwoofer.  Fantastic condition.  Glass top intact.  The corners (sharp edges) have a small amount of stain coming off, but touch up with a furniture touch up stick and you won't see (the finish is matte, not glossy).  Sub was mated with a 802D B&W Surround System with Pre-Pro a Onkyo modified by The Upgrade Company (yes, this sub got me lots of noise complaints from my neighbors, please don't buy if you live in an apartment/condo - it's too much bass - that echoes through walls, only buy if you have a dedicated house).
Moving out of state, and this sub is, honestly, huge.  The box is so big it won't even fit in a car.  Local pickup available - but, this sub is easily over 100 pounds and the box is too big to fit in a standard car.
I do have the OEM Rel Box and will include with purchase.  I have a copy of the original instructions (print out from Internet).  
Includes OEM Rel cable (I prefer to use aftermarket for connection, but already sold).
Shipping will be via FREIGHT - buyer to pay actual cost.  I'm going to ask for $500 and will refund any difference in actual cost.  If you want to come to Creve Coeur, MO to pick up for free, no problem (just make sure you are strong enough and have a truck/van). As I travel, it may be up to 2 weeks before I'll be available for pickup/to arrange shipping. WOULD PREFER LOCAL ST. LOUIS, MISSOURI BUYER.
Shipping weight is approximately 150 pounds. FYI, Actual shipping will be about as advertised of $500 (of course I'm selling at under market value... So the final price, I believe, is still fair).  If in Canada, please contact me BEFORE purchase to clarify shipping/duties.
