Nick is working to reduce all types of compression and distortion:
1) BL compression by using a linear motor topology
2) Thermal compression by making it more efficient, coating the pole with copper for thermal transfer, and using the enclosed basket as a heatsink.
3) Inductance related effects by taking down inductance by 300% (shorter coil, copper coated pole)
4) Optimized surround and spider for less suspension related parameter shifts and distortion
And various other tweaks here and there //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Lots of thought went into this design to make it extremely low distortion while keeping weight and depth down.
