Does anyone use a RUMBLE filter?

Snap! Snap! Snap!

Be cool boys.

What's the frequency response of a full range orchestra? Is it practical to apply bandwidth filters? Regardless of what the original recording engineer did, the mastering engineer will probably limit the bandwidth to what he considers appropriate for the intended media.

Dear Actusreus: probably you don't know how filters works so take a look on internet to learn about other that what Onhwy61 posted.

Now, we have a limited frequency range through our ears and obviuously that we can't be aware of a wider frequency range hearing what happen in that wider range but you have to remember that frequencies and distortions generates harmonics too that modulate the frequency range where we " live ".

If we have woofers pumping this is a system anomaly somewhere in the audio system and we have to fix it before try the use an " asprin ".

The analog medium is so imperfect that IMHO we have to take care not doing more " imperfect " creating higher distortions becuase that " asprin ".

Regards and enjoy the music,

Onhwy61, If everything's perfectly aligned and no pumping, then filter will 'sleep' and won't 'degrade' performance. If the filter is needed, than it will just save your speakers.

I suspect the RIAA filter is good?? With a rumble filter, I suspect, there is no phase shift because you are cutting out subsonic frequencies, not crossing over to them on a different driver.
