Question about sibiliance. (1 Viewer)

[BryanDO]

My center channel (Athena AS-C1) seems to be very bright. It has alot of sibilance and female voices sound bright and harsh. My receiver has a center channel equalizer, I'm curious as to what frequency produces the most sibilance and female voices. Is it more midrage (3k-5k) or higher (10k plus). I can understand that it varies between system and room. But just in general. Thanks.

You're fortunate to have a center channel EQ with adjustable frequencies.

If the overall sound is bright, you might need an basic roll off of the high frequencies. If the treble EQ is shelving, start at about 6 kHz. Experiment with different cut values and frequency centers until you get something that sounds right. If you move the frequency setting, you’ll probably want to move it lower.

If it’s merely sibilants that are the problem, and not the highs in general, and if your treble EQ can be set for bandpass, try cutting a few dB between 6-10 kHz.

Thanks alot Wayne, I cut a little bit out from 3k to 10k the majority being at 6k and it sounds wonderful now, really knocked down the sibilance.
