I have an ESP Kit that I built. It is a 4th order 2200Hz active XO. The frequency can be changed by changing 8 resistors.
It is fully assembled, and uses OPA2134 Opamps, 1% metal film resistors, and 2% Panasonic film capacitors in the filter sections. In the PSU decoupling sections, it uses Panasonic FC capacitors.
These are some of the best components available and give it a very clean sound.
I am selling it for $60. The board alone costs about $20 from ESP, and the rest of the components in this board easily account for the other costs, as well as not having to burn your fingers.
Free shipping to the 48 states as well.
