Buy High Pass Filter or KAB RF1?


Is a $25 high pass filter as effective for rumble as the $180 KAB RF1?

I would rather spend the lesser amount. Thanks!

Your calculation is wrong. Your nagaoka has 6cu dynamic compliance only when it’s measured at 100Hz just like all japanese cartridges.

For your calculation you must use dynamic compliance measured at 10Hz (not at 100Hz), this is a problem if you don’t know.

Convert 6cu @100Hz to 10Hz

6 x 1.7 = 10.2 cu

this is a compliance of your nagaoka at 10Hz , now you can use this data for calculation of tonearm/cartridge resonance. Actually it can be from 10 to 12cu compliance. The range of RF is 8 - 15hz 





Update: I also moved the sub farther away and now I have no rumble whatsoever.

I’m happy that I won’t need a rumble filter now

Exactly, i don’t understand why anyone need those filters.
You can properly isolate your turntable from vibration, AT’s pneumatic insulators are very effective. Here is how it works.
