how to properly measure hpf & lpf

[CrownMe 10+ year member]

hey,

I know I'm probably missing a simple way of doing this... must likely using a dmm or something. But I was wondering if there was an accurate way of testing the highpass filter and low pass filters and subsonic filters.

I often find my self guesstimating when I'm tuning my amps.

I just wanna know if theres an accurate way of checking exactly what frequency the filter is set at instead of just estimating.

Thanks

filters tend to taper off so it'd be hard to figure out the tone exactly. I'm sure if you grabbed a CD of test tones you could measure with some accuracy

hmm, yea that's what I was thinking of too, but there's gotta be a way to do it with even more accuracy than that, i figured.

an osciliscope is the only accurate way I believe..... I have a handheld one I bought from partsexpress that makes it REALLY easy to do.... $175 new
