This may seem like a stupid question but please bear with my n00bness. The TSX HU has seperate Bass and Treble controls. How much of the 20Hz-20kHz spectrum does each control? I mean is going +1 on Treble the same as going -1 on Bass and increasing the volume? Or does Bass adjust the lower 1/3-rd and the Treble control the upper 1/3-rd of the spectrum?

It's all set at a certain Hz/KHz.
+ and - only boost the signal it does not raise or lower the Hz.

That's not a stupid question at all. I've always assumed they were at 100 Hz and 10kHz with 6dB of boost or cut, but I've never checked. I guess I'll check when I do this other stuff...

Dude,

jlukja

Yes. What I was getting at is, for example, when you adjust Bass from 0 to +1, does the bass boost occur from 20Hz to 100Hz, or 20Hz to 5000Hz, or is it more of a bell curve centered at 100Hz or some other frequency. Sorry for the poorly phrased question. I think elduderino got the gist of it.

Usually, as far as I know, bass controls have a fixed center, like 100hz, and raise the other freqs near it on a curve, like you mentioned. So, my guess is that that is what it's doing. But I'd test to make sure if you need to know.

elduderino

No, it's still a well-put question.

Alpine used to have some Hus that had a 30 Hz bass center frequency and a lower "Q" (narrower band of effect) and a 15K treble frequency, and a few Hus have used shelf filters instead of symmetrical filters for the treble.

But I don't think that's true for the TSX... and today when testing the response, I forgot to check! : (

Don't have an answer but an observation I made the other day. With the crossover point set at 85Hz (bi-amp setup) and the sub disconnected, I could barely notice a +/-2 change of the base control. Anecdotal yeah, could be the speakers, my ear, whatever, but also could be that the center point is less than 100 Hz. Curious to find out.
