Phoenix Gold QX900.1d Class D Mono Subwoofer Amplifier
Designed and engineered by the same maniacal engineers that brought you the acclaimed Titanium Series, the completely rebuilt QX Series shatters the barrier of price vs. performance. These amplifiers are simply the best technology and build quality available at these prices.

The QX Series includes many features and technological advances only high priced amplifiers offer - certainly not available at this price range - UNTIL NOW! Things that make a difference like huge rail voltage capacitance (double the amount of the closest competitor), double-sided circuit board (unlike the unreliable single-sided boards most companies use at this price point), fully complimentary output stage and bi-polar technology. All of this leads to high-fidelity signal reproduction, increased dynamics and better reliability.

Robust low ESR capacitance on the voltage rails
A fully complimentary output stage that is balanced between both ends of the heatsink allows for maximum heat dissipation
All potentiometers and switches are located externally for easy adjustments
All signal and power supply terminals are gold plated for protection against corrosion and audio degradation

A high quality, double-sided circuit board is used for the entire amplifier. This ensures better reliability and a longer lifetime of the amplifier
All power and speaker terminals are screwed to the 18 gauge metal end panels for "Makita Proof" durability
Heavy-duty buss bars create a low impedance path to the power supply
