The best way to keep sound equipment in top condition is to understand how it works and what affects its performance. For new subwoofer owners, here is a summary of how a sub operates and how to improve its audio quality.
When it comes to investing in a home theater system, there is no way a person won’t consider adding a subwoofer in the mix, unless the buyer already has one. Home theater systems that come in a set have a subwoofer. For example, a 5.1 surround sound consists of five main speakers and one subwoofer. The plus one in surround sound units is the subwoofer.
The Concept of Subwoofers
What is the first thing that comes into your mind when talking about subwoofers?
Bass has become synonymous with subwoofers. It is not surprising since the subwoofer’s basic concept is to reproduce sounds with very low frequencies, known as bass. This sound equipment can recreate sounds roughly at the bottom two octaves ranging from 20Hz to 80Hz.
It is why a subwoofer is needed in home theater systems. The main speakers can’t pick up lower frequencies, which make the sound groundless and hollow. Adding a subwoofer fills the void in the sound main speakers produce, thereby creating more depth and color.
How does it operate?
Subwoofers are connected to the audio receiver, also known as a preamplifier. The receiver’s function is to send low frequencies from 20Hz to 100Hz signals. Professionals refer to these signals as LFE or low-frequency effects. These signals are sent to the subwoofer in the form of an electrical current.
Once the signals arrive in the subwoofer, the latter converts them into sounds using the magnetic coil. The magnetic coil causes the vibration of the driver’s cone, which later produces the sounds and sends them out to the air.
Good Bass is Not Always about Subwoofers
If you’re planning to purchase a home theater system or a subwoofer, it is better to go big than sorry. You can find a wide variety of surround systems with high-quality performance; examples of it are available here at Home Cinema Effect.
However, take note that good bass is not always about subwoofers. Though a high-quality sub does enhance sound quality, correct placement and a room’s acoustic properties also play a major role in producing good bass.
A room’s acoustic properties have a paramount significance when it comes to producing good bass. Even if you buy the best subwoofer in the market, but place it in an acoustically poor room, do not expect to obtain great results. Thus, make sure your room has decent acoustic properties. Remove objects that could block the delivery of sound waves in the room.
Take note that low-frequency signals are omnidirectional. Consequently, subwoofers have more flexibility concerning placement. However, make sure to position the subwoofer where the bass is clearer to the listener. Searching for the best subwoofer placement might take time. You’ll have to do some trial and error to find that sweet spot in your room.
Once you follow these tips, you’ll get good bass from your subwoofer. No doubt, every movie experience with your new surround sound is worth having.
