Ok.. I've been doing a little research and testing with WinISD Pro and I've decided that I'll be getting the e12k.44 but it wont be in a sealed enclosure. It'll be in a 2.0cuft box ported and tuned to 26Hz. This will allow a nice linear response and the -3db cutoff will be at 24Hz.. which is pretty low and I doubt I need to listen to anything lower.
