Boosting bass with EQ

post #1 of 7
Thread Starter 

If I wanted to boost the bass on my speakers with EQ, would it be ok to cut everything else and leave the bass frequencies (like <80hz) at 0db? Could this damage anything?

Cutting is always better than boosting. smily_headphones1.gif

Yes, cut the frequencies rather than boosting them. If I'm not completely wrong here you'll get exactly the same results, minus the distortion that might come with the boosting.

It's always the better idea to do subtractive EQing, unless your EQ has a limiter(like the Xonar one), which in that case it doesn't matter.

A dynamic compressor/limiter still degrades the sound, even if not as much as clipping. A good EQ should have a volume/gain control to attenuate the overall level, so that you could e.g. add a +6 dB boost at 50 Hz, and a -6 dB or less overall gain to avoid clipping. With a parametric equalizer, this is the approach that makes sense, rather than creating a more complex EQ to cut the other frequencies.

I was under the impression that limiters simply pushed down the gain of everything when bands were set too high, essentially doing the exact same thing that a subtractive EQ would. Am I wrong here?

Limiter indeed does something different; it's function is to make sure that the output signal will not exceed the designated value. 

 

The simplest digital limiter would just examine every sound sample and if it's value is lower than the limit it is passed through unchanged, and if higher then the max allowed value is passed instead. In practice this would create pretty bad clipping, so real limiters/compressors use something like logarithmic scaling which is more tolerable to human ears.
