8" Polypropylene Cone Woofer
Your Radio Shack 8" Polypropylene
Cone Woofer lets you increase the
bass response of your sound system, whether it is a home or car, stereo or monaural system.
FEATURES
Light, Rigid, Polypropylene Cone
— extra-durable, long-life cone resists effects of moisture and temperature extremes, and withstands
greater stress at high volume levels.
Rolled Urethane Foam Surround
— minimizes distortion and improves clarity.
Long-Throw Voice Coil — delivers
clean, solid sound.
MOUNTING
You can install the woofer from the
front or back of an enclosure so it is
flush with the baffle’s surface. Seal
the mounting surface so air cannot
leak around the woofer.
For details, see our “Building Speaker Systems” book (not supplied),
available at your local Radio Shack
store.
