Punch Audiophile Woofer manual
INTRODU CTI ON
This manual provides information on the construction, installation and operation of the Punch Audiophile Woofers. We suggest you save this manual for future reference.
The Punch Audiophile woofers are a full line of low frequency drivers in 8", 10", and 12" sizes; in 4 or 8 ohm impedance. They are designed for use primarily in small, sealed enclosures. By utilizing the latest materials and construction techniques, we are able to offer a speaker with good, low frequency response while requiring a minimum of operating space.

Cone – The cone material used is spruce pulp paper reinforced with Kevlar® fiber (8" and 10" only). This provides the necessary combi- nation of weight and strength and allows high levels of output without cone break up. The cone is treated with a water resistant Polyvinyl Acetate Emulsion (PVA) which increases the cone rigidity and lowers distortion.
Vented Pole Piece – To allow operation at reasonably high power levels, ventilation is needed. This is done through the use of a vented pole piece. The venting allows fresh air to circulate and remove the built up heat from the voice coil assembly.
Suspension – The suspension holds the cone to the basket and supports the voice coil in the magnetic gap. The suspension should allow the cone to move in and out freely but not allow side to side motion. The Punch Audiophile woofers all use a Nitrile rubber surround for the front and a flat spider design for the rear. This combination takes full advantage of the Kevlar® cone's stiffness allowing clean, uncolored reproduction.
