I installed one in a .4 cu ft sealed off a JBL CS200.1 set up for just under 200 watts.
Sub bottomed out and bent the former...sent in the sub. ED won't warranty it.
Never buy this sub. eD's "5 year warranty" is a piece of crap.
If you do buy there subs...after a year or two just find a way to split the surround from the cone without it looking like it was done on purpose...then they should warranty it. If not..you will get screwed.
