My comment:
Not much to complain about, cone is reinforced with something that looks like a carbon fibre, basket is not very restrictive, voice coil is much taller than in the SW10BG32. The one I had had an incredibly ugly dust cap, but that might differ. Parameters in the datasheet that comes from the manufacturer are way off
