Artisan R1000 Audiophile
Active Subwoofer
 Iso-Cone
Here is a close up of the Solid Aluminum  bi axis decoupling Iso - cone developed to provide true bass with dynamic speed by reducing the resonate modes twice and isolating the floor response which normally distorts low frequency bass notes. Unwanted resonant  is removed by the solid brass cone tip decoupler which assists in decoupling  the Enclosure  from the floor  room modes. This speaker will reproduce flat to 18.1 HZ with the active amplifier parametric frequency control set at 25 Hz.
