He doesn't list a price, just "best offer takes it". What is a good price for a used sub?
If I decide to jump on it what should I check on it before I buy it? It is not in a build, just loose. I figured I would check the resistance and but what do you look for visually?
Any advice would be appreciated.
The Dayton Audio 15 Titanic MKIII TIT400C-4 is no longer being sold by Parts Express.
Its spec sheet can still be found at http://www.parts-express.com/pe/showdetl.cfm?partnumber=295-420
It has been superseded by the Dayton Audio RSS390HF-4 15" Reference HF with a current net price of about $170.

You can compare these two web pages at your leisure.
The most important single spec of a subwoofers of the same cone area is Xmax or linear cone travel.
The Dayton Audio 15 Titanic MKIII TIT400C-4 has Xmax of 20.5 mm
Dayton Audio RSS390HF-4 15" Reference HF has Xmax of 14 mm
It seems to me that the Dayton Audio 15 Titanic MKIII TIT400C-4 is potentially the better driver. It compares to the Integrity Audio 15" with Xmax of 22 mm and a price of 170 http://stereointegrity.com/index.php?id=60
Of course the big unknown in used equipment is the actual condition of the equipment. If not abused the lifespan of a speaker driver ranges from about 10 years or more for subwoofers with foam surrounds to virtually unlimited for subwoofers with cloth or rubber surrounds.
The above information can be used to choose or design enclosures that will exploit the capabilities of the drivers.
I think that a fair offer for a used driver in good condition would start at a fraction of the price of a comparable new product - running from 1/4 to 3/4 depending on its condition and how earnest you are.
