Hi Guys,
I am looking for a variable (40-150Hz) low pass 3rd or higher order filter to use in my plate amp , that i am going to use to drive a 8inch ported sub . Is it possible to have a flat response or does the response peak/dip while changing the crossover point? All the cheap chiness ones i saw on ebay has that same problem with frequency response peaks or dips . Ideal low pass filters response should be relatively flat till the crossover point. Is it possible with a couple of opamps and a dual gang pot ?
And mini DSP is not an option as of now🙁 that's why going the analogue route...
Nudge me in the right direction .....😕
cheers

Once you are set up in your music room, you'll find the room acoustics completely overwhelm all other determinants of FR near the crossover frequency. So you need to install the system and explore what crossover frequency and slope seems to make the most sense.
Frankly, I can't imagine ever again living with the compromises you are stuck with unless you have a DSP in the middle. No reason to be without a DSP today.
