If you use your home theater subwoofers conservatively, they should last for many years. However, if you often „crank them up“ to their maximum volume, they may not last as long as you’d like. Fortunately, there are several ways to increase the life of your speakers.
In-wall home theater subwoofers are becoming a popular option for custom installers. Brands like JL Audio, Paradigm, B&W and others manufacture in-wall subwoofers. It is not recommended to install in-wall subwoofers yourself, unless you are an expert in repairing drywall. If you do so, you run the risk of alienating your neighbors.
Subwoofers are available in different sizes and shapes and are designed to enhance bass. They tend to be large and stick out like a sore thumb. An in-wall subwoofer, on the other hand, is small enough to be hidden without taking up floor space and looks good.
The price of an in-wall home theater subwoofer depends on its quality. Those with higher price tags have more features and a longer lifespan. On the other hand, cheaper models may not last as long and may have less durability. Therefore, you should do your research before buying a subwoofer.
Generally, a subwoofer with a large driver will have more bass. This is because drivers with a larger surface area tend to be more susceptible to distortion, and a large driver is more difficult to control. In addition, big drivers are less accurate at producing bass and can struggle to start and stop on a dime. They can also produce bloated, smeared sound in the low frequencies.
The primary reason a subwoofer’s volume displacement is important is because it predicts maximum loudness for a given frequency. In addition, the square of the radiating area is the woofer’s efficiency. The larger the radiating area, the higher the efficiency.
Subwoofers that have multiple drivers can offer a more powerful output. The impedance of each driver will affect the total output of the subwoofer. For example, a 4 ohm speaker will receive twice the power of an 8 ohm speaker. Consequently, it is important to consider the impedance of each driver and use the appropriate wiring configuration.
A corner placement will reduce phase cancellations because sound waves that are of a particular frequency cancel each other out, creating nulls or holes in the response. For this reason, it is best to move the subwoofer at least a few feet away from a wall or corner.
Room correction for home theater subwoofers is a process of adjusting relative levels between the subwoofer and the main speaker. This is done by using software that makes educated guesses about the distance between the two speakers. Then it applies equalization and filters to the output channels.
Room correction is integral to the performance of a subwoofer. It helps remove standing waves, resonances, and other unwanted influences. The software has proprietary algorithms that calculate room contributions and correct them to improve the overall performance of the system. This process helps the subwoofers perform optimally and avoid muddying reflections.
Some subwoofers have built-in room correction that uses a microphone to analyze the frequency response at your listening position. They then automatically optimize their performance to match this new location. Room correction can make a subwoofer sound smoother and more natural. However, you should remember that there are limitations to this technology. It can be difficult to find the right room correction setting, and the setup time can be significant.
