PRO-CSW1200 12" Car Subwoofer
Your RadioShack PRO-CSW1200 12" Car Subwoofer
lets you increase the bass response of your vehicle’s
sound system. When mounted inside an enclosure, your
sub-woofer’s high-output, low-distortion design provides
quality, bass sound reproduction. The subwoofer’s long-
travel voice coil lets it handle high input power with ease.
Note: To connect the subwoofer to your stereo amplifier’s
wires, you need 2 banana plugs such as Cat. No. 278-
306 (not supplied).
CHOOSING AN ENCLOSURE
To get the best performance from your subwoofer, you
must mount it inside an enclosure. An enclosure makes
your subwoofer more efficient and improves its sound
quality.
Some common enclosure designs are:
• Acoustic suspension (sealed)
• Ported reflex (vented)
• Single reflex bandpass (vented)
For more information about a single reflex bandpass en-
closure, see “Single Reflex Bandpass (vented)” on
Page 2.
To learn more about and build an acoustic suspension or
ported reflex enclosure, we recommend you use the book
Building Speaker Systems
(Cat. No. 62-1087A, available
at your local RadioShack store) along with this Owner’s
Manual. That book has complete information about build-
ing enclosures, including obtaining construction materi-
als, and design and construction tips.
Note: Check with RadioShack Unlimited for a pre-built
enclosure for this subwoofer.
ENCLOSURE SIZES
After you choose an enclosure type for your subwoofer,
for the best results, build the enclosure to the dimensions
recommended in this section.
