Douk Audio G100 Bass Shaker Amplifier for Tactile Transducer/Subwoofer 100W

Features Built for Real Tactile Bass: Purpose-built bass shaker amplifier for tactile transducers. Designed to drive Douk Audio BS-1/BS-2 and similar bass shakers, the G100 provides dedicated low-frequency power for adding more physical feedback to gaming chairs, home theater seats, sofas, and sim racing rigs. Flexible BTL/PBTL Output Modes: Use BTL mode to power two bass shakers with 50W×2 output for wider tactile coverage, or switch to PBTL mode for 100W×1 mono output to drive one shaker with stronger, more focused impact. Also supports passive subwoofers for more flexible setups. Adjustable Low-Pass Filter: The 50–300Hz adjustable low-pass filter lets you control the bass range sent to your shaker, helping focus on deep effects like engines, explosions, impacts, and cinematic bass while reducing unwanted higher-frequency vibration for cleaner, tighter feedback. RCA and Bluetooth 5.3 Input: Connect easily by RCA input from a TV, computer, audio player etc. or use Bluetooth 5.3 to receive wireless signals from phones, tablets, and computers. Bluetooth reset is also supported for easy reconnection. Stable Build for Long Sessions: Optimized circuit design, upgraded heat dissipation, and quality components help maintain stable low-frequency output during long sessions. Its compact aluminum chassis fits beside your audio system, under a seat, or in tight spaces. Q: Can the G100 be used as a full-range amplifier? A: No. The G100 is designed for low-frequency output, not for driving regular full-range speakers. All outputs are limited to low-frequency signals by design and are optimized for subwoofer or bass shaker applications. Q: What is the difference between BTL and PBTL modes? Which one should I use? A: BTL mode is used to connect two passive subwoofers or bass shakers, with 50W×2 output at 4Ω. PBTL mode is used to connect one passive subwoofer or bass shaker with higher output, with 100W×1 output at 2Ω. Use the appropriate mode based on your setup and requirements.
