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.
