W-1000
Commentary

A 30 cm cone woofer unit developed for the Lab series speaker system.

The W-1000 uses a string damper (thread suspension type damper) for the damper part.
This eliminates the non-linear effect of woven fabric, which is unavoidable with conventional cloth dampers, and the non-linear effect of air generated by the trapped air gap in the voice coil.
