When I first chanced upon this Tang Band 5″ mid-woofer, I didn’t know what to make of it.

The magnet is massive for a 5″ mid-woofer. More than that, it is designed with an “underhung” voice coil. This is unusual for most are “overhung”. An underhung voice coil has an advantage that the entire coil is immersed in the magnetic field during it’s travel. This translates to less distortion when playing loud.

Eventually, my curiosity got the better of me and I bought a pair. I was determined to see whether this driver lives up to its potential.
