going NEO motors on them ID`s I don`t think so the NEO`s will run you min.$250US each unless they changed the cost of them so thats $500 to put motors on then you need to recone them after that.You would be best to go with the REVO subs in Neo version.This would save cash as the parts for the sub will be down a bit and I know they work well together.Another good thing is the SQ and SPL will be way better with the audiopulse
Audiopulse » Subwoofer Drivers

There are others out there that do Neo subs like eD and others but it is not realy in the line up that they offer so it will be big $$$

Here is an auction for Neo Axis subs to get an idea
