A self-powered subwoofer adds sonic punch to the home theater experience by delivering deep, low-frequency effects. The heavy bass sound can be felt as well as heard, adding a new dimension to movies, sporting events and music. Some home theater aficionados might find the subwoofer sound so addictive that they want to add a second sub to the system. The beauty of a powered subwoofer is the built-in amplifier that drives the bass speaker without drawing power from the main home theater receiver. On the downside, many receivers only come with one dedicated subwoofer jack, which uses an RCA-type audio cable for the connection to the sub. Get around that problem with an RCA signal splitter.
Instructions
1. Insert the plug on the Y-adapter into the receiver's Sub Out jack. The RCA-type plug inserts straight into the jack.
2. Plug an RCA subwoofer cable into each of the jacks on the Y-adapter.
3. Route the cables to the two subwoofers. A powered sub can be placed anywhere in the room where it won't be in the way. Subs produce an omnidirectional sound, so placement is not critical the way it would be with other audio speakers.
4. Plug a cable into the Input jack on the back of each sub, then plug the power cable on each sub into a surge protector and connect to an outlet.
5. Adjust the volume and crossover controls on the back control panel of each sub to the desired level.
