SAX-100.4 (A,B,C Revision)

The SAX-100.4 is the second "X" series multi-channel amplifier to come from Sundown Audio. This model is built to the same exacting standards as the SAX-100.2 but adds another set of channels and more advanced crossovers. It's flexible crossovers allow the user to run a 2-way active speaker setup with no external processing. It packs enough punch that one could also run a set of front speakers with one pair of channels and a subwoofer, bridged, on the other pair of channels for use as a total system amplifier where high power is not required.
