Should I use subsonic filter?
Registered. Yes, you definitely want to run a subsonic filter when using a ported box. The port acts as part of your subwoofers suspension and once you’re below the tuning frequency it becomes an extra stress on the soft parts and loses it’s ability to maintain linear control over your cone movement.
What is subsonic HPF on AMP?
SUBSONIC FILTER – is basically a HPF (high pass frequency) filter for your subwoofers. As we discussed earlier in this article, subwoofer amps typically use LPF (low pass frequency) filters to block high frequencies that should be playing through your speakers.
What Should low pass filter be set at for 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 my high pass filter be set to?
As a general starting point, you should place a high pass filter on each channel and adjust it according to the lowest frequency the sound source can produce. For example, a male vocal will not contain frequencies lower than about 80 Hz….
| Frequency | Attenuation |
|---|---|
| 50 Hz (three octaves below 400 Hz) | -36 dB |
Should I have the Low-Pass Filter on subwoofer?
What phase is best for subwoofer?
in-phase
One of the other controls you may find on your subwoofer’s rear panel is marked “phase.” It’s provided because the speakers and subwoofer sound best when they are in-phase — meaning their woofers move in and out in sync with each other.
What should my high pass filter be set on my subwoofer?
Recommended Starting Points:
- Front Component Speakers – High-Pass Filter = 80 Hz (12 db or 24 db Slope)
- Subwoofer(s) – Low-Pass Filter = 80 Hz (12 db or 24 db Slope)
Do I need a subsonic filter for my car amplifier?
But if you’re a fan of the ones that do (and you know if you are), you need a subsonic filter to keep your subwoofers from rattling themselves to bits before their time. Check out the MTX Audio THUNDER1000.1 Thunder Series Car Amplifier for a great amp with a subsonic filter.
How do I set LPF filters on my subwoofer AMP?
To set LPF filters on your subwoofer amp, an easy way is to disconnect the RCA’s to any amplifiers that are not powering your subs. Be sure that all equalizer settings (bass, treble, front/rear, etc) in your head unit or at “0” or flat. We don’t want any head unit settings affecting the sound we are trying to tune with the amplifier adjustments.
How to set a subsonic filter on a subwoofer?
Each octave up is twice as many Hz as the previous one, and dividing any frequency by 2 takes it one octave lower. Therefore, to get your subsonic filter setting, take your subwoofer’s tuned frequency and multiply it by 0.75.
What type of crossover should I use with my MTX amplifier?
On MTX amplifiers, you can select which type of crossover you want to use based on the kind of speakers you are powering with the amplifier. For example, when using smaller speakers such as a 4”, it would be a good idea to use the HP or HPF crossover to protect them from the lower frequencies they are not intended to reproduce.
