The TAGA Harmony THUNDER SW-15D 15-Inch Active Subwoofer is designed for powerful, deep and dynamic bass in high-performance home theatre and Hi-Fi audio systems. Featuring a large 385mm (15-inch) paper cone woofer with THAW and TSAC technologies, the THUNDER SW-15D is engineered to deliver strong low-frequency impact with fast response and controlled bass reproduction.

At its core is a high-current 20A Class D amplifier delivering 650W RMS and 800W dynamic peak power. The amplifier is designed for high efficiency and strong current drive, supporting lower distortion, smooth and flat response, fast operation and reduced operating noise. An integrated clipping limiter helps protect the amplifier and woofer while maintaining performance during high-volume operation.

The subwoofer uses a TLIE enclosure with a single rear slotted bass reflex port to support powerful low-frequency output. Its frequency response extends from 25Hz to 150Hz, while the variable 40Hz–120Hz crossover filter allows flexible integration with AV receivers, amplifiers and speaker systems.

The THUNDER SW-15D also provides line-level L/R, SUB/LFE and high-level L/R inputs, making it suitable for different home audio configurations. A removable Schuko-IEC C13 power cord provides a practical upgrade path for users looking to use a premium audiophile power cable.

With its 15-inch driver and high-power Class D amplification, the THUNDER SW-15D is built for listeners seeking substantial bass output for demanding home cinema, music and gaming applications.
