Question About sealed or bandpass

I think those subs are designed for use in small sealed enclosures so that's probably what I would go with.  You can't really go wrong with sealed boxes it's just sometimes you need to put a lot of power into the subs to get a lot of output, but I think with those amps you won't have much of a problem getting some good loud bass.

if i may ask, what type of vehicle will you be putting these subs in. usually a bandpass box in a large, open vehicle will not be very loud where you will be listening to it. Also, if you put the bandpass box in the trunk of a small car, it is more than likley going to make EVERYTHING rattle if it is not properly secured. in the end, this is what i would do, going with my experience (however limited):

small surrounding area = larger sealed boxes with lots of power
