Video: How to make your passive subwoofer into an active subwoofer
A passive subwoofer is one that requires the use of an external power source, such as an amplifier or receiver. Passive subwoofers are ideal for large rooms that may need multiple units and are preferred by home theater designers.
Speakers and subwoofers - which are mostly different in terms of both need to draw power from a source in order to produce sound. For passive subwoofers, selecting an amplifier or receiver that outputs enough to power to properly sustain the deep tones produced by your device is important. You will also need to consider how much power will be necessary for your speakers if you are using it in conjunction with the rest of your home theater sound system.
A passive subwoofer may appear more complex when it comes to connecting all the pieces. This is because, not only do you have the source components, but also the additional amplifier. This means you will need more cabling.
Passive subwoofers are most commonly used by those with custom home theater system installations. In fact, many passive subwoofers are mounted in or on a wall as part of a custom installation. Passive subwoofers themselves are often cheaper than active subwoofers, however, custom installations and a more powerful receiver can bring this cost up.
Passive subwoofers also allow you to link multiple units together for larger or dynamic home theater rooms. This means you can spread the bass throughout the room without creating muddied sound or worrying about uneven distribution.
Active subwoofers, also known as powered subwoofers, include their own power source, such as a built-in amplifier. Active subwoofers are easy to set up and are best used in a single subwoofer configuration. Because of this, placement is more important with active subwoofers.
Active subwoofers are typically configured in a way that optimizes each of the built-in components. Because the built-in amplifier is perfectly matched to the power needs of the speaker, active subwoofers are an all-in-one solution for many home theater owners and designers.
Active subwoofers do not require as many cables as their passive counterpart. This means that set up is typically easier as well. That being said, an active subwoofer requires more power (watts) to work. This may appear negligible for some when they receive their power bill, but it is still worth mentioning here.
Because they include everything you need for optimal bass sound, active subwoofers are typically more expensive than passive models. More importantly, however, when Dolby Digital 5.1 became the standard for DVDs, Blu-ray and more, it established a new norm. With five main channels and a Low-Frequency Effects (LFE) channel, Dolby Digital 5.1 paved the way for a designated bass channel. Active subwoofers tend to capitalize on this designated channel and can provide quality sound from a single unit, instead of having to use multiple ones.
Passive vs Active Subwoofers: Which is Better?
There are pros and cons related to each type of subwoofer. Each of these should be weighed to help you decide which subwoofer is best for your intended use. Sound quality is an obvious factor when searching for the right subwoofer. Regardless of the type of subwoofer, quality depends more on the specific make and model you choose. Aside from sound quality, the six key features are:
Receiver/Amplifier: Does the subwoofer require an external amplifier? If so, how strong does it need to be?
Power: How many watts does it take to power your subwoofer? Can your receiver/amplifier support this level of power?
Connectivity: What types of cables will you need and how many?
Expense: What will the subwoofer cost you? Are certain types more expensive than others are? Do not forget to factor in the costs of all required components.
Set-Up: How easy will the subwoofer be to set up? Do you simply plug it in and play or is set up more complicated?
Design: What features are included with your subwoofer? Can your subwoofer be easily integrated into your décor? Are you looking for a more custom approach?
