A passive sub woofer is great for being used in a small room that does not need the powerful sound. This passive subwoofer is small, and not as bulky as a powered subwoofer. The sound it produces is less intense. Passive subwoofers are both mono and stereo. They do not have any amplification.

Passive subwoofers cost less and can be worth their cost if you are able to find one that can be used with your existing speakers. When adjusting a passive sub woofer's output or cross over you will experience sonic problems. The passive subwoofer will blend correctly if they are using the speakers they were designed to work with. They do produce a higher quality when they have a good power supply and circuits. They are able to power several other passive subwoofers in a home theater room.

1. Cost Effective

If you have a multiple channel amplifier you will be able to power several passive subwoofers in a home theater. Passive subwoofers are easier and cheaper to build. The cabinets for a passive subwoofer can be large and it also gives you much more flexibility in where you place the woofer and the ports. Your amplifier can be replaced with any external amplifier if it happens to malfunction.

2. Less Chance of Fire Mishap

With a passive subwoofer you have less of a chance for a fire mishap. You can place them in any location. You can actually run speaker wires directly to the sub woofer and not even need a wall outlet. Long speaker wires are more cost effective than the cables for subwoofers. Flat speaker wires are also easier to hide then the subwoofer cables are. When the sub woofer is not being used, a general purpose amplifier can power other speakers in two channel music.

3. Low Frequency

The design of passive subwoofers broadens their potential to generate the lowest frequency. Some passive subwoofers have a passive high pass for the output to the speakers. If you have a set of small speakers and you want to add some bass kick to them, then passive subwoofers will be a good choice for this. If you have a dedicated external amplifier, passive subwoofers are the best option for giving them power.

Your amplifier or receiver will need to have the ability to put out enough power to keep the bass effect of the passive subwoofer without draining itself. The amount of power will depend on what is required of the speaker and the size of the room you are trying to provide the sound quality for. In order to produce low frequency sounds, bass will actually need more power. The amplifier will need to be able to have enough power to do that.

The passive subwoofer will take the entire signal from your receiver as with any other speaker would. The low frequency of a passive subwoofer can take the movies you watch or the television programs and give them a boost for better sound quality.
