As far as i know, there's no chip including these effects ready to use.

You will probably need to implement something like a dsp.

A Chinese company called Trig Audio makes DSP effects modules. I never actually used them so I can't comment further.

Crossover solution for speakers products, buy Crossover solution for speakers products from alibaba.com
