It's a win-win situation for the amp, the driver and my sanity. For example, if the Subsonic Filter is set to 30 Hz, only frequencies above 30 Hz will be passed. This will also keep me from wasting precious amp power trying to reproduce anything below (practically useless anyways), which translates into less energy consumption and less heat = amp longevity. The Subsonic Filter will block frequencies below its set level. In either case, it would seem that filtering this before the signal hits the amp stage is going to not only be better, but easier on the wallet. Play that tone and turn the subsonic up until it settles down, so you can play tones back down and it does not have more excursion. Right, or play tones lower and lower and when it unloads excursion will go up you will see it. But its the same thing as Ultrasonic: tenth-order Butterworth highpass filter.

I'm farther ahead whether I build my own pre-amp filter or use something like a Behringer Ultragain Pro MIC2200 ($100). As a very general rule of thumb, I usually set an infrasonic filter 1/3 octave below tuning frequency. TL DW: Infrasonic is a very clean, plain, high quality subsonic filter. After seeing the values needed for a 35Hz filter and trying to find inductors and caps that are even close to what I'd need, the cost would be non-beneficial. But I was thinking it would be cheaper to design a post-amp filter as opposed to pre-amp. spart Leistungsreserven für den optimalen Frequenzbereich des Subwoofers. Passive crossovers aren't exactly known to be efficient. So funktioniert ein Subsonic-Filter: Schneidet die Frequenzen (HP) unterhalb 20-30Hz für den Subwoofer ab. I do agree that it's best to put the filter on the pre side of things as opposed to post-amp. While xlim is really more of the concern, it's better safe than sorry. Modeling for my cab shows this driver will reach xmax at 31.59Hz with a 400 watt signal. Since the 16-46 is physically tuned to 16 Hz, probably a decent starting point would be an 18 Hz corner, 12 dB/octave or 24 dB/octave slope, and a Q value of 0.6-0.8 (this will depend on how much room gain is present, the shape of the subwoofer corner/knee in-room, and. To remove this unwanted low frequencies, subsonic filters like the circuit featured here is used. This happens independent of the applied recording medium. In a ported box: You tune the port to a certain frequency, the enclosure is then capable of playing all frequencies above that tuning without an issue. For a sealed enclosure you adjust the subsonic filter to 25-35 Hz, to filter the extremely low bass frequencies your woofers unable to play. Most often, the very low frequencies create distorsions in music recording or reproduction. So for safety, we want to cut those frequencies out. Since both are nice head amps and costs around £150, Id suggest the Phono Box S or the CA CP2 as your best long-term option. It is quite possible to send subharmonics through the cab with an ill placed slap or pop. Ideally you'd want to use a high pass filter which had three adjustable variables - corner frequency, slope, and Q value. A subsonic filter is mostly used in low frequency technology. In addition to the Pro-Ject Phono Box S Steve mentions, the Cambridge CP2 has a (switchable) subsonic filter as well as supporting both MM and MC cartridges.

The second option is obviously cheaper, but in the long run option one is more convenient for upgrading the amp/phono stage, as I will unlikely have to ever change the KAB RF1.Click to expand.Well for 1, synth may very well find it's way to this cab. A subsonic filter is mostly used in low frequency technology. You can insert a subsonic filter and connect to the auxiliary input. If your turntable already has a built-in phono preamp. Highpass filter to cut out the low, inaudible frequencies below 15 Hz - 20 Hz and thus protect bass speakers from damage from overloading. I have come up with a few options:īuy a preamp with that: Basic angle audio phono stage, Rega Fono Mini ?īuy a preamp with a built in filter: Pro Ject Phono Box S, Cambridge Audio 651p. The only way is to connect the turntable to a phono preamp, then a subsonic filter and then to the auxiliary input of the integrated amplifier. Unfortunately I can't put it between my phono stage and amp as required, so I'm going to have to buy a phono preamp and filter separately (or together).

I aim to try and get rid of most of it by isolating the turntable as much as I can (also any advice on this would be appreciated) but I think I want to get a subsonic filter involved in my system too. The floors are wooden and bouncy and it makes my speakers angry. Due to my old speakers having covers I never noticed the woofers 'pumpng' because of subsonics. I have a Denon PMA720AE amp and a Rega RP1 (w/ Bias 2) (I realise the speakers outclass these, it's all a long game).
