The RF Punch Woofers are a full line of low frequency drivers sized
from 8" to 18" and are available in 4 or 8 ohm impedance. The RF
Punch woofers were designed for use primarily in small, sealed
enclosures. By utilizing the latest materials and construction tech-
niques, we are able to offer a speaker with high output at low
frequencies while requiring a minimum of operating space.

ECHNICAL
Stamped Basket
The RF Punch Woofers use a stamped Cold Rolled Steel basket which
is rigid and lightweight. The basket is finished in a corrosive resistant
powder coated applied process used in many automotive applica-
tions.
THE RESULT: A lightweight and rigid woofer
PVA Cone
The cone material used is spruce pulp paper. This provides the
necessary combination of weight and strength and allows high levels
of output without cone break up. The cone is treated with a water
resistant PolyVinyl Acetate (PVA) Emulsion which increases the cone
rigidity and lowers distortion.
THE RESULT: Increases cone rigidity and lowers distortion
Inverted Dust Cap
The use of the inverted dust cap serves to increase the cone rigidity and
improve the power handling by forcing more air through the voice
coil.
THE RESULT: Increases cone rigidity, smooths frequency response
and prevents your friends from feeling obligated to invert them for you.
