The enormous BL from the huge motor makes the 8" cone more suitable for use on the end of the midrange horn (though I guess since high compression ratios aren't involved, the horn works more like a waveguide). The Community M4 is basically a compression driver built around an 8" cone. But the magnet is comparatively even larger than the one on Raj's driver. If the horn had a higher compression ratio, I'd still have no reservations about Raj's driver's ability to drive it. In a smaller, lighter motor design, a Neodymium magnet would have been used, but I imagine that for Raj, ferrite donuts are what is available to him, so the very large motor structure is as a result of working with what's available. And it is a purpose-built midrange with an Xmax of +/- 2mm, so an extended T-yoke is not needed. Don't be hatin'.
