2/29/2024 0 Comments Setting subsonic filterThis is where the need for a subsonic filter, or in other words, the high pass filter, arrives. So when you play a piece of music or any audio below 30 to 25 Hz, the waves may damage your audio system because of the stress it goes through. If you exclude a subsonic filter, the graph will represent waves that move significantly, but when below a certain level, the graph will drop. Well, whenever your amplifier/subwoofer plays an octave lower, the excursion increases by a few factors, which is four. While working, the cone excursion of all speakers increases by a few points. For an answer, you need to have an idea about the power handling of an amplifier/subwoofer. Many question why low bass is necessary when subwoofers’ purpose is the opposite. So make sure to set everything at once and at the right limits. Not doing so will damage your amplifier and subs, which is not something you want. This is exactly what a subsonic filter does with waves with frequencies lower than your set limit.īut while setting the limit of your high pass filter, you must also set the amp’s gain accordingly. Just consider you fixed the switch in the middle. A subsonic filter is not an on-off switch. You can adjust this filter at different levels depending on the music you mostly listen to. This is where a subsonic filter differentiates from a low pass filter that only attenuates signals that are above the limit you set for low frequency. The amplitude of those lower frequencies is brought down, you think, overpowers the high notes. So, the low notes that were a cause of frustration will no longer come out of your speakers. This will not allow any sound below a certain hz threshold. When a sound wave of 20 Hz is produced, it will pass through but won’t be as high as before, and you won’t hear it to the same extent you did before.īut if you wish for a sealed enclosure, we recommend you set your high pass filter to 20 Hz or 25 Hz. Unlike a low pass filter, a subsonic or a high pass filter allows low frequencies to still pass through without causing distortion.įor example, you set your subsonic filter frequency to 30 Hz. Infrasonic or subsonic are sound waves below par at a certain frequency that can reach a human ear. Warning: After reading this guide, you may become a bit of an expert yourself! Subsonic on Amp So sit back, relax, and let’s dive into the world of Subsonic! What Is Subsonic on Amp? In this guide, we’ll cover everything from understanding subsonic filters to tuning them correctly for optimal performance. Setting subsonic frequencies correctly can be tricky, and getting it wrong could lead to damage to your woofer or even your entire system. These filters control intensities and can make or break your system’s performance. That’s why we’ve created the ultimate guide to help clear up any confusion.Īs someone who has spent years installing car audio systems, I know firsthand how important it is to understand subsonic filters. Many people are unsure of what to do when they see this term. Have you ever been confused by the label “Subsonic” on your amp? Don’t worry you’re not alone.
