Midrange Features
◆ PVA Treated Cone
The lightweight paper cones are treated with PVA (PolyVinyl Acetate) for
environmental stability and increased rigidity. This treatment promotes
smooth midrange performance and low frequency extension free of
distortion.
THE RESULT: Strong and lightweight high performance cones.
◆ Vented Pole Piece
The vented pole piece by design, ensures proper ventilation to cool the
voice coil and maintains lower operating temperatures. This increases the
thermal power handling of the speaker.
THE RESULT: Improves power handling by cooling the voice coil.
◆ High Temperature Voice Coil
The voice coil used in the Punch Series is of a high temperature copper
wire construction. The wire is wound in two layers on a black anodized
aluminum voice coil former. The voice coil former dissipates heat away
from the voice coil improving the speaker’s thermal stability and improv-
ing the reliability of the speaker.
THE RESULT: Improves reliability by dissipating generated heat.
◆ Nitrile Rubber Surround
The nitrile material is resilient to temperature variations and provides a
consistent support necessary for the linear motion of the speaker cone. In
addition, the inherent damping capabilities eliminates the transmission of
degrading sonic disturbances between the cone and the frame of the
speaker greatly improving the clarity of the speaker’s midrange frequency
response.
THE RESULT: Improves speaker's frequency response.
