What Is Subsonic On Amp?

Are you curious to know what is subsonic on amp? You have come to the right place as I am going to tell you everything about subsonic on amp in a very simple explanation. Without further discussion let’s begin to know what is subsonic on amp?

In the world of audio enthusiasts and music lovers, the pursuit of high-quality sound is a never-ending journey. One critical element of achieving audio perfection is the management of low frequencies, and this is where Subsonic on Amp comes into play. In this blog, we will explore what Subsonic on Amp is, its significance in audio systems, how it works, and why it’s essential for audiophiles seeking an unparalleled listening experience.

What Is Subsonic On Amp?

Subsonic refers to sound frequencies below the threshold of human hearing, typically below 20 Hz. While these frequencies are inaudible to most people, they play a crucial role in audio systems, especially when it comes to subwoofers and deep bass reproduction. Amp, in this context, generally refers to an amplifier, which is a device used to increase the amplitude (power) of an audio signal.

Subsonic on Amp refers to a feature or capability that is often found in amplifiers, particularly those designed for use with subwoofers. This feature is designed to filter out or reduce extremely low-frequency signals that are not only inaudible but can also be detrimental to both the amplifier and the subwoofer.

The Significance Of Subsonic On Amp

Subsonic frequencies, while inaudible, can cause several issues in audio systems:

Overloading the Amplifier: Extremely low-frequency signals can overload the amplifier, leading to distortion and potentially damaging the amplifier or the connected speakers.
Wasted Energy: Subsonic frequencies demand a significant amount of power from the amplifier, which can result in inefficiency and wasted energy.
Speaker Damage: Continuous exposure to subsonic frequencies can cause the speaker cones to move excessively, potentially damaging the subwoofer and affecting its lifespan.
Reduced Clarity: When an amplifier is forced to reproduce subsonic frequencies, it may compromise its ability to accurately reproduce audible frequencies, leading to a loss of audio clarity.

How Subsonic On Amp Works?

The Subsonic on Amp feature operates as a high-pass filter designed to block or attenuate frequencies below a certain point, typically set by the user. This point is known as the “crossover frequency.” When subsonic frequencies are detected, the high-pass filter prevents them from reaching the amplifier and subwoofer, ensuring that only audible frequencies are reproduced.

Here’s How The Process Generally Works:

Crossover Frequency Setting: The user sets the crossover frequency, which determines the point below which subsonic frequencies will be filtered out.
Signal Processing: The audio signal from the source (e.g., music player or receiver) passes through the amplifier. As it does, the Subsonic on Amp feature processes the signal.
Frequency Filtering: Any frequencies below the crossover point are filtered out or attenuated, preventing them from being amplified and sent to the subwoofer.
Clean Signal: Only frequencies within the audible range pass through the amplifier and are amplified, resulting in cleaner and distortion-free audio.

Why Subsonic On Amp Is Essential?

Subsonic on Amp is essential for several reasons:

Protection: It protects both the amplifier and the subwoofer from damage caused by extremely low frequencies.
Improved Efficiency: By filtering out subsonic frequencies, the amplifier operates more efficiently, reducing power wastage.
Enhanced Clarity: Removing subsonic frequencies ensures that the amplifier can focus on reproducing audible frequencies accurately, leading to better audio quality.
Extended Speaker Life: Subsonic filtering can extend the lifespan of subwoofers by preventing excessive cone movement.

Conclusion

Subsonic on Amp is a vital feature for audiophiles and audio enthusiasts who want to achieve the highest level of sound quality while safeguarding their audio equipment. By effectively managing subsonic frequencies, this feature enhances the listening experience, protects against damage, and optimizes the performance of amplifiers and subwoofers. For those who appreciate deep, clear bass and pristine audio quality, Subsonic on Amp is an indispensable tool in the quest for sonic perfection.

FAQ

What Should Subsonic Be Set To On Amp?

– If there is no specific recommendation, a common starting point is to set the subsonic filter frequency half octave below the enclosure tuning or to around 80% of the enclosure’s tuning frequency for easier calculation (e.g., if enclosure tuning is 35 Hz, set the subsonic filter to 28 Hz.

What Should I Set My Lpf And Subsonic To?

The universal go to bandpass setting on a sub amp is 30Hz on the Subsonic and 80Hz on the LPF.

Is A Subsonic Filter Necessary?

If it’s vented, you would definitely benefit from a subsonic filter(a filter that cuts off sound below the tuning frequency of the box). It might NOT be necessary if the drivers have very good power handling ability, long cone travel and you aren’t feeding them that much power.

What Does Subsonic Mean In Audio?

subsonic in American English

1. noting or pertaining to a speed less than that of sound in air at the same height above sea level. 2. noting or pertaining to a sound wave with a frequency below the audio-frequency range; infrasonic.
