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 reprodu ction. The subwoofer’s long travel voice coil lets it handle high input power with ease.

To connect the subwoofer to your stereo amplifier’s

Note:

wires, you need 2 banana plugs such as Cat. No. 278306 (not supplied).

CHOOSING AN ENCLOSURE

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.

Acoustic Suspension (sealed)

—

To get the best performance from your subwoofer, you must mount it inside an enclosure. An enclosure m akes 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 enclosure, 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 System s

(Cat. No. 62-1087A, available at your local RadioShack store) along with this Owner’s Manual. That book has com plet e in format ion ab out build ing enclosures, including obtaining construction materials, and design and construction tips.

A single reflex bandpass enclosure combines the features of acoustic suspension and ported reflex designs. In this type of enclosure, one side of the subwoofer is mounted in an acoustic suspension en closure, while the other side is mounted in a ported reflex enclosure.

A single reflex bandpass enclosure controls the movement of the speaker’s cone at low frequencies (like an acoustic suspension enclosure), and has the ability to sacrifice efficiency for deeper bass or vice versa. The frequency response of the sing le reflex bandpass enclosure is controlled by the volume of the enclosure.

Due to the complexity of its construction, a single reflex bandpass enclosure can be difficult to design and build. If you are inexperienced at building enclosures, we recommend that you build an acous t ic sus pension or port ed reflex enclosure.

1. Run one wire from eac h of t he subwoofer’s terminals to the stereo amplifier.

2. Separate each wire’s two conductors at both ends for a length of about 2 inches, then strip the insulation from the ends of each con ductor to expos e

3. Twist the endcap from a banana plug (not supplied) to remove it, route one of the speaker’s wires through the endcap, then fold the exposed wire around the top of the endcap.

4. Twist the banana plug back onto the endcap as shown here.

5. Repeat Steps 3 and 4 for each of the subwoofer’s wires.

6. Press the banana plugs into the subwoofer’s terminals to connect them.

CONNECTING THE SUBWOOFER TO YOUR STEREO AMPLIFIER

We recommend you use 12-gauge or thicker wire (such as Cat. No. 278-1268, not supplied ) to connect the subwoofer to your stereo am plifier. For the m aximum bass response and the best overall performance, be sure to connect + to + and

to –.
