Quick Answer: How Do You Set A Subsonic Filter?

What should my gain be set at?

To set the gain you want the maximum range of bandwidth, so you should turn the equalizer settings off or set them to zero.

This prevents the filtering of any sound waves.

Turn the gain to zero.

This usually means turning the dial counter-clockwise as far as it will go..

What do I set my subsonic filter to?

Turn your Subsonic Filter down to 10Hz then slowly turn up the filter frequency until you hear it take effect on your sub bass. The Subsonic is now correctly set. 5. Turn the Low Pass Filter to the setting that allows for the most accurate sub bass sound for your system.

What should LPF be set to?

Recommended Starting Points:Tweeters – High-Pass Filter = 5,000 Hz (12 db or 24 db Slope)Midrange – Band-Pass Filter = 80 Hz HPF & 5,000 Hz LPF (12 db or 24 db Slope)Subwoofer(s) – Low-Pass Filter = 80 Hz (12 db or 24 db Slope)

What Hz is best for bass?

20-120 HzA 20-120 Hz rating is best for bass in most subwoofers. The lower the Hz, the more is the bass you can get. Some of the best subwoofers in the market have this Hz range. If you are buying a subwoofer that has a fixed Hz rating, you should ensure it is lower than 80 Hz if the bass is important to you.

What Hz should I set my car speakers to?

Thus, the recommended settings are a HPF (5000 Hz) for the front tweeters, a HPF (80 Hz) for front midrange, a HPF (80 Hz) for rear speakers and 12 dB or 24dB slope. If rear speakers (passive) are added to this system, the settings will change a little bit.

What does a subwoofer low pass filter do?

A low pass filter prevents a driver (subwoofer in this case) from playing frequencies above it (a high pass filter does the opposite). So for example, a low pass filter of 80 Hz will only let frequencies below 80 Hz through to the driver.

How do you adjust a low pass filter on a subwoofer?

As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response. For example, your speaker’s frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer’s low pass filter to 30Hz.

What should I set my HPF and LPF to?

You usually set the HPF with a steep slope say 24db/octave because you are trying to protect the sub from damage and a 12-18db/octave on the LPF because you want it to kinda “blend” in with your mids. The steeper the slope (db/octave) the less your sub will creep into the neighboring frequencies.

Can a subwoofer port be too big?

Remember, there is such a thing as too big. As the size of the enclosure increases, the mechanical limits of the woofer will be easier to reach. … If the port becomes too small, it may result in port noise, or allow the woofer to simply unload.

Is 40 Hz low enough?

Many say that they can live without subs, but most full range speakers typically go down to 40hz.

What does a low pass filter do?

A low-pass filter (LPF) is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design.

How do I tune my amp to LPF?

With only one amp receiving signal from your head unit, play your favorite type of music at about 75% volume with the LPF filter on your amp set as high as it will go. Slowly turn the dial from high to low until you stop hearing all the high frequencies through your subwoofers.

Does polyfill help subwoofer?

The material is easy to apply to the inside of your subwoofer enclosure and allows you to add the perfect amount of fill so your box appears bigger to the subs which will then produce better audio quality. … In these cases you can easily add some Polyfill to the box to increase the effectiveness of your subwoofer.

What is subsonic frequency?

Infrasound, sometimes referred to as low-frequency sound, describes sound waves with a frequency below the lower limit of audibility (generally 20 Hz). … and rarely to 0.001 Hz.

What does subsonic mean on AMP?

High Pass FilterA subsonic filter is basically a High Pass Filter for very low frequencies, generally 45hz or lower. That is, whatever you set it at; only frequencies above that setting go through. Anything below that setting is attenuated (made quieter). As only frequencies higher than your setting pass its a high pass filter.

What is a good crossover frequency?

What is the recommended crossover frequency for a subwoofer? For THX Certified and non THX Certified home theater systems, 80 Hz is the recommended setting. However, you can set the crossover (LPF) between 80 Hz – 120 Hz based on which setting sounds best for your system.

What should LPF be set at for LFE?

This is the high frequency cutoff point for the LFE, also known as the . 1 channel in a 5.1/6.1/7.1 surround source. In practice this should always be set to 120Hz since the LFE channel supports information up to that frequency.

Is a subsonic filter necessary?

Subsonic filters are good for keeping the wattage of the amp powering the frequencies you want powered, and not wasting power trying to reproduce very low frequencies. I cannot say that you NEED a filter, but it does somewhat depend on your music tastes.

How do you set a low pass filter?

As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response. For example, your speaker’s frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer’s low pass filter to 30Hz.
