If I had 300 ounces of magnet, I'd make it as shallow and wide as possible.
This new Fi speaker is shallower, but only by about an inch, according to the pictures. It's still a LOT thicker than the MAG. And it has a very large and deep back plate (certainly bumped internally), which means a long magnetic path through the steel. While that is better than air, it is not as good as flowing through magnet, so it will be a bit lossier than it needs to be...

nice reply
and i mean that, very nformative to me, and it somehow still made sense (dont know how since im still pretty sloshed...), but each woofer has its design and purpose, and like you said, the BTL apparently doesnt need to be super accurate, so it has a large area for the coil/cone to go non linear.
