Is a BIC America F12 really that bad?

Is a BIC America F12 really that bad? I picked up one of these with a faulty amp for around the same price as Starbucks coffee.
I've temporarily converted is to passive and connected it to my LG home theatre system where it is probably crossed to high. It sounds okay, plenty of sub-bass but not too good with actual musical (air) bass.
I suspect the plate amp's problem is with the power MOSFETS and I've ordered some replacements.
I'm coming to the conclusion I'm only fixing this because I can. I don't really want it.
Should I trash the box and sell the driver?
