Key Benefits
Subwoofer models featuring monstrous power, yet capable of sensitive sound reproduction.
They also offer flexible installation options suited to your style.
✹
Pure Sound from Hemp-Fiber Cone and Dustcap
Eco-friendly Hemp-Fiber reduces unwanted mid and high
frequencies in subwoofers – like a natural low filter. Internal
Loss is reduced within the speaker diaphragm for pure
fidelity sound.
✹Exclusive Cone and Spider
- Repeated tests made for improving amplitude
performance of cone and spider. (left)
- The unit can faithfully
reproduce transmitted
signals (sound), and even
process long-stroke signals
that are often lost.
The vertical axis shows stroke signals,
the horizontal axis shows stiffness.

✹Easy Installation
Rapid Fire Impedance Selector Terminal
- Changes the voice coil impedance with one easy motion.
Switch between Parallel, Series, or Bi-Amp configurations
without any additional wiring. Terminals are also fused
which prevents damage caused by current overloads.
✹Smart Trim Ring
- The ring allows both forward and
backward attachment, and together
with the special screws, provides a
neat installation.
The Innovations Design and
Engineering Award is based
upon descriptive materials
submitted to the judges.
CEA did not verify the
accuracy of any submission
or of any claims made and
did not test the item to
which the award was given.

Heat Transfer Silicon
Aero Vent Bottom Plate
The T3 chassis enhances heat dissipation and prevents sound pressure decline. The Aero Vent causes air fluidization in the center, and the Heat Transfer Silicon provides smooth
heat transfer for prompt radiation. The heat is also dissipated from the Air Vented Aluminum Cast Basket. The outer form of this subwoofer also promotes heat loss.
Sound Pressure Level
The sound pressure decline is limited to less than 1 dB, providing powerful and pure sound.
