Color Organ Design

[aep9690]

I am designing a color organ.  The idea is that I would plug a headphone plug into it and then the board would filter it into bass, mid and high range which would then use darlington transistors to drive a couple high power 1W LEDs.  I simulated it using pspice and it worked they way I wanted, but simulations can only go so far.  I attached the schematic I have and was hoping I could get some feedback before I go into PCB layout.
