When it comes to amplifiers, there are numerous features and settings that can be overwhelming for beginners and experienced audiophiles alike. One such feature that often raises questions is the “subsonic” setting. What does subsonic mean on an amplifier, and how does it impact the overall sound quality? In this article, we will delve into the world of subsonic frequencies, explore the concept of subsonic on an amplifier, and discuss its significance in the realm of audio reproduction.
Understanding Subsonic Frequencies
To grasp the concept of subsonic on an amplifier, it’s essential to understand what subsonic frequencies are. Subsonic frequencies refer to sound waves with frequencies below 20 Hz, which is the typical lower limit of human hearing. These low-frequency sounds are often felt rather than heard, and they can have a significant impact on the overall sound quality.
Subsonic frequencies can be caused by various factors, including:
- Low-frequency rumble from traffic or wind
- Vibrations from the amplifier or speaker
- Low-frequency resonance in the room
These frequencies can be problematic because they can cause the amplifier and speaker to work harder, leading to increased power consumption, heat generation, and potentially even damage to the equipment.
The Role of Subsonic on an Amplifier
So, what does subsonic mean on an amplifier? In simple terms, the subsonic setting on an amplifier is a filter that helps to remove or reduce subsonic frequencies from the audio signal. This filter is usually a high-pass filter that allows frequencies above a certain cutoff point (typically around 20-30 Hz) to pass through while attenuating frequencies below that point.
The subsonic setting on an amplifier serves several purposes:
- Reduces power consumption: By removing subsonic frequencies, the amplifier doesn’t have to work as hard, which can lead to reduced power consumption and heat generation.
- Prevents damage to equipment: Subsonic frequencies can cause the amplifier and speaker to work excessively, leading to potential damage. The subsonic filter helps to prevent this damage by removing these frequencies.
- Improves sound quality: By removing unwanted subsonic frequencies, the subsonic filter can help to improve the overall sound quality by reducing rumble and vibrations.
Types of Subsonic Filters
There are several types of subsonic filters that can be used on an amplifier, including:
- First-order filters: These filters use a single capacitor and resistor to attenuate subsonic frequencies. They are simple and effective but may not provide the steepest slope.
- Second-order filters: These filters use two capacitors and two resistors to provide a steeper slope and better attenuation of subsonic frequencies.
- Third-order filters: These filters use three capacitors and three resistors to provide an even steeper slope and better attenuation of subsonic frequencies.
The type of subsonic filter used on an amplifier can impact the sound quality and the effectiveness of the filter in removing subsonic frequencies.
How to Set the Subsonic Filter on an Amplifier
Setting the subsonic filter on an amplifier can be a bit tricky, but here are some general guidelines:
- Start with the manufacturer’s recommended setting: The manufacturer may provide a recommended setting for the subsonic filter, so it’s a good idea to start with that.
- Experiment with different settings: Listen to the sound quality with different subsonic filter settings and adjust to taste.
- Use a subwoofer with a built-in subsonic filter: If you’re using a subwoofer, it may have a built-in subsonic filter that can be adjusted to optimize the sound quality.

What is Subsonic on an Amplifier?
Subsonic on an amplifier refers to a feature designed to filter out extremely low-frequency sounds, typically below 20 Hz. This feature is often used in home theaters and car audio systems to prevent the amplifier from producing sounds that are not audible to the human ear. By filtering out these low frequencies, the amplifier can focus on producing clearer and more defined sounds within the audible range.
The subsonic filter works by attenuating or reducing the amplitude of low-frequency signals before they reach the amplifier’s output stage. This helps to prevent the amplifier from wasting power on sounds that are not audible, which can also help to reduce distortion and improve overall sound quality. By engaging the subsonic filter, users can optimize their amplifier’s performance and enjoy a more refined listening experience.
Why is Subsonic Important on an Amplifier?
Subsonic is important on an amplifier because it helps to prevent damage to the amplifier and the speakers. Extremely low-frequency sounds can cause the amplifier to work harder, generating more heat and potentially leading to overheating or damage to the amplifier’s components. By filtering out these low frequencies, the subsonic feature helps to reduce the amplifier’s workload and prevent damage.
Additionally, the subsonic feature can also help to improve sound quality by reducing distortion and hum. When an amplifier is not equipped with a subsonic filter, it may produce low-frequency rumble or hum that can be distracting and affect the overall listening experience. By engaging the subsonic filter, users can enjoy a cleaner and more refined sound that is free from unwanted low-frequency noise.
How Does Subsonic Affect Sound Quality?
The subsonic feature can have a significant impact on sound quality, particularly in systems that are designed to produce deep bass. When the subsonic filter is engaged, it can help to reduce low-frequency rumble and hum, resulting in a cleaner and more refined sound. However, if the filter is set too high, it can also affect the overall bass response, making it sound thinner or less defined.
To get the best sound quality, it’s essential to adjust the subsonic filter carefully. A good starting point is to set the filter to around 20-25 Hz, which is the typical lower limit of human hearing. From there, users can adjust the filter to suit their personal preferences and the specific requirements of their system. By finding the right balance, users can enjoy a sound that is both clear and defined, with deep and satisfying bass.
Can I Adjust the Subsonic Filter on My Amplifier?
Yes, many amplifiers allow users to adjust the subsonic filter to suit their specific needs. The adjustment is usually made using a potentiometer or a switch, and the range of adjustment can vary depending on the amplifier model. Some amplifiers may have a fixed subsonic filter, while others may offer a range of adjustment from 10-50 Hz.
When adjusting the subsonic filter, it’s essential to listen carefully to the sound and make adjustments in small increments. This will help users to find the optimal setting for their system and avoid over-filtering or under-filtering the low frequencies. It’s also a good idea to consult the amplifier’s manual or manufacturer’s instructions for guidance on adjusting the subsonic filter.
Do All Amplifiers Have a Subsonic Filter?
Not all amplifiers have a subsonic filter, particularly lower-end models or those designed for specific applications. However, many modern amplifiers, especially those designed for home theaters or car audio systems, often include a subsonic filter as a standard feature.
If an amplifier does not have a built-in subsonic filter, users can also consider using an external subsonic filter or a crossover network that includes a subsonic filter. These external solutions can provide similar benefits to a built-in subsonic filter and help to improve sound quality and prevent damage to the amplifier and speakers.
How Does Subsonic Differ from a Crossover Filter?
A subsonic filter and a crossover filter are both used to filter out unwanted frequencies, but they serve different purposes. A subsonic filter is designed to filter out extremely low frequencies, typically below 20 Hz, while a crossover filter is used to divide the frequency range between different speakers or drivers.
A crossover filter is typically used to separate the frequency range into different bands, such as low-frequency, mid-range, and high-frequency. This allows different speakers or drivers to handle specific frequency ranges, resulting in a more efficient and effective sound reproduction. In contrast, a subsonic filter is used to filter out a specific range of low frequencies that are not audible to the human ear.
Can I Use a Subsonic Filter with a Subwoofer?
Yes, a subsonic filter can be used with a subwoofer, but it’s essential to adjust the filter carefully to avoid affecting the subwoofer’s performance. A subwoofer is designed to produce low-frequency sounds, typically below 80 Hz, so it’s crucial to set the subsonic filter to a frequency that is lower than the subwoofer’s operating range.
A good starting point is to set the subsonic filter to around 10-15 Hz, which is lower than the typical operating range of most subwoofers. This will help to filter out extremely low frequencies that are not audible to the human ear, while allowing the subwoofer to produce the desired low-frequency sounds. By adjusting the subsonic filter carefully, users can enjoy a more refined and controlled low-frequency response from their subwoofer.
