SoundTube A3 AMP Internal Class AB Subwoofer Amplifier
The Induction Dynamics A3 amplifier is engineered to pair seamlessly with audio/video pre-amplifiers and receivers featuring built-in low‑frequency crossover circuitry. Designed for applications with selectable crossover frequencies—recommended at 80 Hz with reverse polarity—the A3 maintains distortion below 0.05% at 1 kHz, ensuring clean, powerful bass reproduction.
Featuring a patented non‑distorting frequency‑selective excursion limiter, the A3 delivers consistent performance at high output levels. Its flexible level control (±19 dB in 0.5 dB steps) and multiple switchable voltage gain settings make it ideal for home theaters, commercial AV, and dedicated subwoofer systems.
