I have a BNIB Pioneer TS-W303F subwoofer. This is a beast of a sub as may of you know they can take well over rated (150rms) FYI I had a pair of the 8" free airs in my rear deck and they were taking 600 rms a piece!!

. Specs are hard to come by but I know these:
92 db sens.
20-1500hz
150rms
I don't have pics right now but could get some.
This is the diamind plate pioneer looks just like this:
Lets say $70 shipped.
