I have a couple of Atlas 15" subs I would like to try one out sealed but the recommended cabinets are quite big like 6 cu.ft. I was wondering if I could get one of these bad boys in a 3cu.ft. cabinet with a LT circuit. I was looking at the Rythmik Audio site and one of the amps the 350 is offered with a optional LT circuit board. I however have no idea how to get the necessary values for the resistors and caps.Any help would be great.
