Well, he is comparing it to the older fathom F112 and not the newer F113 which is much more highly regarded and which the PB13 Ultra is rated even more highly than for half the price of the F113. But none the less it does sound like a promising sub only problem would finding a dealer or shipping costs.

The sub I have been looking at lately is the MFW-15 over at av123, now that seems to be the best bang for the buck, still under $1000 delivered to my door but have to wait till July to see/hear one if I ordered now.
