DOUK AUDIO G100 Subwoofer Amplifier

The Douk Audio G100 is a subwoofer amplifier relying on Class D amplification via a TPA3116D2 chip paired with a pre-processing stage based on four NE5532 op-amps to stabilise the signal and ensure controlled bass response. It delivers up to 2x50W into 4Ω in BTL mode, while its PBTL configuration concentrates current capacity to reach 100W into 2Ω, enabling efficient drive of dedicated low-frequency drivers while maintaining stability under demanding loads.

Intended for car audio simulation setups or home theatre systems, it integrates an adjustable low-pass filter spanning 50Hz to 300Hz, allowing precise tuning of the subwoofer's frequency range to suit the application, while the RCA input and Bluetooth 5.3 connectivity facilitate integration with a variety of sources.
