It wouldn't be too hard for you to build bass modules (errr...subwoofers) and slap amps on the back of them. There are several guys on AC who would be happy to sketch it up for you. You could probably build two modules for less than half the cost of a pair of OB servo subs, but the trade-off is they won't sound as good and the NX Studios deserve the best bass.
When the time comes I'll have to contact Denton Woodworkers and have them custom build a pair of Brute's for me or modify a pair of the sealed sub for the Eminence woofers. I dont have a shop or the capability to even assemble a large flat pack much less build something from scratch.
I dont care about having the best bass, I want mid bass impact and to make my Studios fun instead of disappointing and frustrating. I have all this money into my system and dont even listen them much anymore because they trigger me
