Overview

The T400-2 is "One of the most impressive amps I've ever seen." says Sergey of K&B Audio. Don't let its size fool you ... this all MOSFET amp packs enough power to run one 2-Ohm DVC or two 4-Ohm DVC subwoofers with ease and its dual function EQ can tune-in any pair of high frequency component speakers to deliver premium sound quality. "The amplifier is without a doubt the most efficient Class A/B amplifier I've ever tested."
