Passive low pass filter ALPUY. I have a pair of B&W DM602s amplified with Marantz PM6006. My interest is to add two subwoofer speakers, one for... YSDR. Passive crossover that low can cause at least as much problems as it solve. Of course they can filter out... SpeakerBob. Otherwise use a plate amp ...

Passive filters can ONLY attenuate. (Substantial) peaks in frequency response are far more sound degrading than dips. This is what these filters do they remove emphasis and bring it down to the proper level. The picture below shows some examples of …

How to Build a Passive Bandpass Filter Circuit

The low-pass filter blocks all frequencies below the cutoff point they are designed to. In the circuit, we want the higher cutoff frequency point to be 10KHz. So the low-pass filter allows all frequencies below 10KHz to be passed through and blocks or greatly attenuates all frequencies above this 10KHz point.

Low Pass Filter Calculator - learningaboutelectronics.com

http://learningaboutelectronics.com/Articles/Low-pass-filter-calculator.php

This passive RL low pass filter calculator calculates the cutoff frequency point of the low pass filter, based on the values of the resistor, R, and inductor, L, of the circuit, according to the formula fc= R/(2πL). To use this calculator, all a user must do is enter any 2 values, and the calculator will compute the 3rd field.
