W-21 is another outcome of “I want to do the best possible” idea, nothing too much to say, these are our crazy products for extreme audiophiles.

We have an ambitious plan to make a mega open baffle with this and Pt-15.

  1. It uses underhung motoring system to realize accurate and deep bass while eliminating distortion.
  2. With Lii Song paper cone of unique material, it has a wide frequency response and transparent sound so that it can coordinate with a great variety of full range drivers.
  3. Double coil design let it competent to be adapted with amplifiers and connect in parallel or in series with other driver units, according to impedance.
  4. Optimized for open baffle usage so you can have fun with these simply using a baffle.
  5. As Lii Song driver developed by the same creator, this is a wonderful companion for other Lii Song full range drivers, especially on open baffle.
