I've upgraded my ISD-V with the NSD driver (two years ago), and I'm wondering if there is a better driver that's been tested to work in a similar enclosure that would be even better than the NSD driver from SVS? I asked SVS about upgrading to the 13" but they said it's not possible.

I took the sub apart since I had to clean and tighten the bass plate, here are the pics;
