Yeah, it will do well in a very large box.

I can't say from first hand experience, but there are a few people that have used highly linear 18" drivers in sealed enclosures that get very good output into the teens. It just takes a lot of power and a very linear driver.

I would always go for a ported sub. If this economy ever recovers I will dedicate some OT$ to a 12ft. cu. ported sub.
