This 18" comes to approximately $630 shipped, Has anyone used this driver? Is it worth looking at at approximately 2/3rd the cost of a lms5400?

|More than twice the ability, actually. Great ability vs. very limited ability would be how I would call it. At least for my purposes, though perhaps not someone else's. (Bass fidelity isn't important with movies, just the ability to go boom. So the Fi Q18 is just fine in that role. But for a system designed to reproduce music with high fidelity...one is a reasonable option, especially at the current fire-sale price. The other is not, though one could argue I suppose that it could be used as a cheap ULF boom-generator in a high-fidelity multisub system, so long as the other subwoofers were considerably better units.)
IOW, I'm saying one is a high fidelity drive-unit, and the other is not. There are other high-fidelity 18's that are cheaper than the NS18 and currently available, notably from Peavey and B&C. They don't have quite the throw of the NS18, but are good drivers and many of them will make plenty of bass to keep up with the mains people actually use. (They should also be much easier to recone if you screw something up.) I think some of them might even be lighter than the NS18, which is extremely heavy for a neo-magnet 18 because of the steel required to make an underhung driver with such a long throw.
By contrast, the Fi Q-series just another excessively long coil driver with no shorting rings in the motor. Note that Fi doesn't even specify the inductance of the Q18. What you'll see from one is roughly what Josh got from the eD sub: plenty of output, at the expense of fidelity due to the high inductance.
Also, based on my experience with Fi, their build quality is sloppy. When they reconed my old Ascendant Audio Avalanche 18, they couldn't even bother to glue the surround onto the basket correctly: I had to poke holes in the foam surround landing just to reach the screw holes! I'd rather have a driver well-made in China than one slapdashedly assembled in the USA, but that's just me perhaps...
