Subwoofer Amplifier using TDA2030 + TIP3055 TIP2955

This Subwoofer Amplifier using IC TDA2030 as a driver power amplifier and adding transistor booster using Transistor TIP3055 and TIP2955 1 Set. Output Power Amplifier about 200 Watt at voltage supply 30VDC. Preamp subwoofer filter using IC LM358 as an om-amp to processing and filtering subwoofer low frequency to deliver for power amplifier. See the circuit schematic below.

Circuit power amplifiers directly above combined with a subwoofer filter lm458, so that the low frequency output power.  

In the block diagram of the amplifier are 1 pieces of IC TDA2030, which speaker output on pin 4 is used to drive TIP booster transistor, so that the power output greater power amplifier. However, use of these transistors can add distortion to the amplifier circuit.
