Making the most of the space available for installing a truly high-end audio system can be a challenge.  With the same design philosophy that went into the award winning HEX Shallow subwoofers come the new HEX amplifiers.  These amplifiers might be small but they are big on performance.  Hex amplifiers feature Diamond Audio's proprietary Hi-Fidelity Ultra efficient Full Range Class D Technology that allows for a full 20Hz to 20kHz frequency bandwidth.  Hex amplifiers have a fully adjustable 24dB per octave crossover.  Two of the HA750.1 mono models can be combined or "strapped" to produce a single 1500 watts RMS channel.  With the new HEX amplifiers Diamond Audio has once again raised the bar on the competition.
