I dont see how it is trolling. Believe it or not.... not everyone likes your product, and not everyone likes the product I like either.
Back to the topic at hand. If I personally had to choose between the drivers mentioned I would choose the RE's and american bass any day of the week. The AB amp should make about double the power of the sundown one with proper power supply, and the RE's have more motor force then the sundown subs. The only thing I will give you about your sundownz subs is they have a cooling vent which would help for playing music but will cost you DEE BEEZ.
