![]() The best you can do is try it, see what happens. No worries, that's not what's going on in your system The isolation platform may or may not improve fidelity. You have not reported any symptom that resembles feedback, which can runaway and cause severe clipping of the amp. (at least that's the objective) The isolation platform can help to reduce subsonic feedback as well, but that would be regular oscillation of the woofer, not the random movement you will see with subsonic warp. DC in an audio signal can be thought of as an infinitely low frequency, and you dont want DC offset in the audio signal that you send to the receiver (and them onward to your speakers and subwoofer). It does help reduce acoustic feedback, and can tighten up your bass. At least reading the manual I could not infer that it has a built-in high pass filter. The problem is that I can't find some filters. I will cost less energy because low tones will be gone. Or am I stuck with some type of Subsonic filter from AudioControl. I wanted to know if I took the chip completely out and left the socket open, would it totally bypass AudioControls subsonic filter. It will reduce excursion off the speaker. I hate to bring up an old thread but, since my DSP (MS-8) has a subsonic filter controllable from the drivers seat. Low frequencies in the inaudible or infrasound range, if not blocked, cause. For instance, movie sound effects often have less subsonic effect than music recordings. It muffles frequencies of the audio band below 20Hz with a slope of 12dB per octave. It’s possible for different types of content to contain variable levels of low frequencies. Decide what kind of audio content you’ll be using. The isolation platform does not reduce record "warp"or "subsonic". Hi, i have been reading on the internet about subsonic filters. The settings for your subsonic filter depend on the audio content. But on records that contain very low bass, it may affect some of the visceral feel of the bass. If whatever youre playing doesnt have any frequency content below 20 Hz then the subsonic filter isnt going to have an audible effect. The subsonic filter does not affect the bass on most music program. the woofers should "jiggle" a little or "pump" moderately. This can be done on a silent part of the record, between bands. If the woofers are pumping wildly (and you hear distortion) then it's excessive. Mechanical noise is typically induced when using palm muting techniques or a tremolo and this can produce. ![]() In particular you want to do this at max volume before the amp clips, or at the max loudness you listen. A subsonic filter is mostly used for piezo elements. How can one tell what's reasonable? Simply observe the woofers. Some amount of subsonic is normal, and does not sap power from your amp, does not reduce your dynamic range when within reasonable limits. Many amps have subsonic filtering built in whether they say so or not. A subsonic filter is a component on your subwoofer that reduces the intensity of notes which come through at lower frequencies. But I must also stress that the filter is optional. The suggestion by is well advised, but the record "warp" subsonic signal is present even on flat records.
