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

A single reflex bandpass enclosure controls the move- ment 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 fre- quency response of the single 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 recom- mend that you build an acoustic suspension or ported re- flex enclosure.

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 sub- woofer to your stereo amplifier. For the maximum bass response and the best overall performance, be sure to connect + to + and – to –.

Note: You can mount an optional speaker plate on your enclosure (such as Cat. No. 274-630) to make it easy to connect the subwoofer to your stereo amplifier. This lets you connect the subwoofer to the plate then connect the plate to your stereo amplifier.

Follow these steps to connect the subwoofer directly to your sound system.

1.Run one wire from each of the 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 conductor to expose 1/2 inch of wire.

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 termi- nals to connect them.

PRO-CSW1200 specifications

Radio Shack has long been a household name in electronics, and one of its standout products is the PRO-CSW1200 scanner. This versatile and powerful radio scanner is designed for both amateur enthusiasts and serious ham radio operators alike. Its primary function is to receive a wide range of frequencies, making it an excellent tool for staying informed about local events, emergencies, and other communication channels.

One of the most notable features of the PRO-CSW1200 is its broad frequency coverage. The scanner operates within a wide spectrum, typically from 25 MHz to 1,300 MHz. This allows users to listen to a diverse array of communications, ranging from police and fire departments to amateur radio operators and marine frequencies. The ability to monitor both analog and digital signals makes this scanner highly adaptable to various communication methods.

The scanner is equipped with advanced scanning technology, including conventional scanning and trunked system scanning. Conventional scanning allows for straightforward monitoring of individual frequencies, while trunked system scanning is essential for following more complex communications networks, such as those used by public safety agencies. The PRO-CSW1200 can handle multiple trunked systems, facilitating seamless switching between channels without missing important communications.

Another standout characteristic of the PRO-CSW1200 is its user-friendly interface. The device typically features a digital display that shows the frequency, signal strength, and the currently monitored channel. This information is crucial for users who want to ensure optimal reception. Additionally, the scanner usually comes with programmable memory channels, allowing users to save frequently listened-to frequencies for quick access.

Connectivity is another strong point of the PRO-CSW1200. Many models come with the capability to connect external antennas, enhancing reception and signal clarity. This is especially important for users in areas with challenging reception conditions or for those looking to expand their scanning range.

The PRO-CSW1200 also emphasizes portability. Its compact design usually makes it easy to transport, allowing users to take it on outdoor adventures, road trips, or anywhere they may need to stay connected. Battery operation options further enhance this portability, enabling users to monitor frequencies even when away from a power source.

In conclusion, the Radio Shack PRO-CSW1200 is an exceptional radio scanner that caters to a wide range of needs. With extensive frequency coverage, advanced scanning capabilities, user-friendly design, and portable features, it remains a reliable choice for those interested in exploring the world of radio communications. Whether for personal use or as part of a more serious hobby, the PRO-CSW1200 offers a comprehensive solution for monitoring a diverse spectrum of signals.
