How to Pick a Subwoofer for a Home Audio System

The subwoofer is one of the most important components of a home audio system. The subwoofer refers to either a loudspeaker or a driver that brings out the bass sounds. It is essential for the high-quality CDs and DVDs that are now being produced, because the subwoofer helps enrich sounds by bringing out low tones and enhancing many movie sound effects.

Difficulty: Moderate

Instructions

Things You'll Need:

• Specifications of the audio system
• Room measurements

1. Decide how much power you want in the subwoofer. The lower the sound, the larger the driver you will need.

2. Think about where the subwoofer will be placed in the room. Subwoofers can produce sounds in multiple directions, so placement of the subwoofer should be considered. To increase the amount of bass produced by the subwoofer, consider placing it near a wall to enhance the acoustics.

3. Decide whether a video-shielded subwoofer is needed. This is necessary when the subwoofer will be placed near a television.

4. Pick either a passive or a powered subwoofer. The passive subwoofer gets its power from an external amplifier, whereas a powered subwoofer contains an internal amp in order to lessen the strain on the one in the home audio system.

5. Use a favorite DVD or CD to test sound quality when comparing several subwoofers.

6. Make sure your subwoofer does not have too much "boom" to it. Although the unit should emit the essential bass tones, the sound should still be clear and balanced, especially if the subwoofer will be used for music.

7. Learn about the return policy of the dealer or store supplying your subwoofer. The one you pick may not work well in your home.

Tips & Warnings

• Even if you don't have the room or money to devote to multiple speakers, the subwoofer is something you should not overlook. Without one, music and movies will lose their richness and quality.
• Some people or dealers refer to subwoofers as "subs." It pays to become familiar with some of the jargon when shopping around.
• Because subwoofers emit sounds in a non-directional way, it is difficult to detect the direction of the sound coming from the subwoofer. Therefore, the best place to put the subwoofer may be in the front of the room or just to the side of the front left and right speakers.
• If your subwoofer is down-firing, you may disturb any downstairs occupants or neighbors. Consider a front-firing subwoofer if you live close to other people.

on 2/5/2008 Another usefull method to determine placement is to place the Subwoofer where you will be sitting. Play something that will produce low bass tones. Now go to the different areas of the room that you will want to place the Subwoofer and you can determine which area sounds the best.
