Amazon has this at a reduced price compared to the normal price of $799.99. Shows only 1 in stock, but it does allow to order more for when they will be in stock. Amazon has it listed as THX Select certified, but it's actually THX Ultra certified.
EDIT: Price is still active, but the sub is now OOS and shows 1-2 months to ship.
