[QUOTE="req, post: 801177, member: 555713"] xbl^2 is just a kind of motor like the TC'x' stuff. re REXXX has xbl^2 - its basically an overlapping magnetic field at the top of the motor (the gap)... they cut a series of rings out of the top plate that focus' several magnetic fields on the same spot increasing BL with less weight due to less material. given - they are still heavy drivers, but they can be MUCH smaller and lighter (ie, av15) and more efficent because less magnets are needed for the high bl and linerarity. other motor structures use similar stuff - DEI has a technology *similar* to this, and i wouldnt be surprised if the H2 will or does use it. its just a nice thing, because it helps keep a linear stroke (less distortion) and it makes a driver (usually) more efficent. but the subs\mids listed are about all that i know of that have this specific motor... but again - some companies hire out adire to do their stuff too, and since adire is growing and starting their own manufacturing plant, they will most likely be doing that even more.
