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.
