What does the subsonic button do?
the subsonic filter is there to cope with any real low level rumble, arm/cart resonance issues or acoustic feedback which can cause issues with pumping woofers.
Do you need a subsonic filter?
You use it only if you need it. The only reasons to use a subsonic filter is to correct the woofers from rumbling/pumping or if you’re experiencing acoustic feedback. From my experience, proper TT isolation from the low frequency output of the speakers has left me with no need to ever turn on a subsonic filter.
What is subsonic on receiver?
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. It’s the opposite of a low-pass filter, which only attenuates signals above a certain line.
How do you break in a sub fast?
Option I: The most common and easiest method is to first install your woofer as you normally would. Next, play your favorite music at low to medium volume and 1/2 gain for 2-3 weeks. You will begin to hear a difference in sound as the woofer starts to break in.
What should my low pass filter be set to?
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 subsonic filter be set to?
For the mainstream listener, setting a subsonic filter around 35 Hz will allow them to hear all their music content, missing nothing on any performance, while protecting their system.
How important is subsonic filter?
A subsonic filter will attenuate frequencies so low that your subwoofer cannot reproduce them OR that humans are incapable of hearing. Subsonic filter is also a very important feature for vented enclosures.
What are subsonic filters?
SUBSONIC FILTER – is basically a HPF (high pass frequency) filter for your subwoofers. A subsonic filter will attenuate frequencies so low that your subwoofer cannot reproduce them OR that humans are incapable of hearing. Subsonic filter is also a very important feature for vented enclosures.
Do subs get louder after break in?
Subwoofers should not get louder as they break-in. Instead, they will adjust to the varying frequencies provided and will most effectively play the sounds that are coming through.
Is subwoofer break in a myth?
It is not a myth. The sub’s spider will loosen up after about 8 hours of play time, allowing more excursion, and thus a louder sound. It doesn’t have to be played super softly during this time.
What should the subsonic filter be set at?
To be effective, a subsonic filter has to be very steep – this allows all wanted frequencies to get through, and rejects those that will only cause problems. Note that my Citation 1 Pre-Amp’s subsonic filter is set at 15Hz. http://sound.westhost.com/project99.htm
Why are subsonic frequencies bad for your subwoofer?
A sealed box is tuned by enclosure volume, larger enclosures tune lower, smaller enclosures tune higher. Subsonic frequencies potentially damage your subwoofer because they make it expend a lot of energy, travel right to the limits of its excursion and play below the enclosures tuning. So for safety, we want to cut those frequencies out.
Do you need a subsonic filter for spin vinyl speakers?
With that said, the sad reality for many (there might be exceptions) users of ported speakers that spin vinyl is that a good subsonic filter is not an option but simply a necessity.
Can a low frequency filter be set to flat?
I initially set my Low Frequency Filter switch to flat until I discovered some very amazing facts.There exists a phenomenon called woofer pumping aka woofer excursion. Frequencies below 20Hz are usually not able to be reproduced, and with the exception of synthesizers and pipe organs, are not a wanted part of the audio spectrum.
