Amplifier subsonic filter
It provides Bass Boost, a subsonic filter, and a variable crossover, and it's 1-ohm mono stable. Plus, you can externally bridge 2 amps together, increasing power and still keeping things simple to operate. Externally Bridgeable The units are externally bridgeable and permit two separate amplifiers to be joined together as one, doubling the power to a single woofer or voice coil. That's over Watts RMS peak!

Some people own amps with subsonic filter buttons that they never turn off for fear of breaking something. A subsonic filter is a component on your subwoofer that reduces the intensity of notes which come through at lower frequencies. It decreases the amplitude of those low notes that you feel more than you hear. Instead, the number you set the filter to represents the frequency as which it starts to reduce the intensity of the sound.
If your subsonic filter is set to 40 Hz, 30 Hz notes will still get through but will be much quieter. Think of the filter as a slope, not an on-off switch.
We absolutely love the feeling of low notes thudding through our whole bodies. Subsonic notes sound awesome, but they also damage your hardware when they get out of control. Too many deep bass thuds can tax the limits of your woofer and cause it to wear out much faster than it otherwise would. Plenty of genres never get anywhere near the 50 Hz range.
The next step is knowing how to make your high-pass filter work for you. The best thing to do is listen. Play some of your favorite bass-heavy tracks and adjust the filter threshold down until the low notes start to reverberate.
Then adjust it back up until the bass notes tighten up again. Your approach to adjusting your subsonic filter depends most heavily on one thing: whether your subwoofer is set in a sealed or ported enclosure. Is the hole for the speaker the only hole? Since the Hz setting on the subsonic filter is the start of a slope, not a cutoff, we want to set it higher than 20 Hz.
The sweet spot for getting some pounding bass without destroying your subwoofer is between 25 Hz and 35 Hz. Then it gets a little more complicated. On ported speaker enclosures, you have to tune the port to its optimal frequency. The tuning frequency acts as a second high-pass barrier, but it does not replace the function of a subsonic filter. Too many subsonic notes can still damage your subwoofer. That means the safest setting for its subsonic filter is half an octave below whatever frequency the port is tuned to.
The hertz scale is logarithmic. Each octave up is twice as many Hz as the previous one, and dividing any frequency by 2 takes it one octave lower. But if you understand how to adjust your subsonic filter, and practice doing it right, you might reap some big rewards. Not only will your low-frequency sound be less distorted, but your expensive subs will last a lot longer. Thanks for reading, and as always, feel free to sound off in the comments below. Enjoy your next ride with your newly balanced bass track!

Subsonic Addiction: How Much Do You Really Hear?
The Subsonic Filter is a filter that cuts out frequencies below 27Hz that we cannot hear and take away the headroom of the amplifier, cause distortion and clogging of the power amplifier and cause a very large deflection of the speaker membranes, leading to their faster wear. The device is recommended especially for bass players and guitarists with seven and eight-string guitars. You can read more about cookies in our Privacy Policy. Select all.

Subsonic Filter
Learn More. A subsonic filter is only practical and functional as long as you set it up correctly. That said, what is subsonic filter? What does it do exactly? How do you set it up correctly and how does one use it effectively? Also known as an infrasonic filter, a subsonic filter is a feature that attenuates the intensity of low frequency notes. It cuts off to a certain degree extremely low bass notes often below the range of human hearing that many speakers and subwoofers cannot effectively reproduce, thereby making the amplifier and the speaker, more efficient.
