    Hi,
    I’m looking for a project of a rumble filter, to cut frequencies below 16hz. I have a SVS CS+ and I had some bottoming problem with a couple of DVDs. The filter would be placed between the receiver and the Sansom amp. I have someone that can built it for me, but he doesn’t know how to calculate the components values.

    Thanx.

    Texas Instruments has some utilities for designing active filters. Filter Pro lets you design Multiple Feedback Filters or Sallen-Key filters based on crossover frequency and filter order -- easy [​IMG] You can specify up to a 10th-order Butterworth/Bessel/Chebychev filter and the program spits out component values -- exact or off the shelf values. The rest: power supply, printed circuit board etc. is left as an excercise to the user.

    You might try plugging the port as a "quick and dirty" solution when playing bassy track loud.
