Douk Audio G100 Bass Shaker Amplifier for Tactile Transducers and Subwoofers 100W Review

The Douk Audio G100 is a bass shaker amplifier priced at $72.99. It is purpose-built for tactile transducers: designed to drive Douk Audio BS-1/BS-2 and similar bass shakers, it provides dedicated low-frequency power for adding physical feedback to gaming chairs, home theater seats, sofas and sim racing rigs.

Output flexibility is its main feature. In BTL mode it powers two bass shakers with 50W x 2 output at 4 ohm for wider tactile coverage; switch to PBTL mode and it becomes a 100W x 1 mono amplifier at 2 ohm to drive one shaker with stronger, more focused impact. It also supports passive subwoofers. Under the hood sit a TPA3116D2 chip and four NE5532 op-amps, with matched impedances of 4-8 ohm in BTL and 2-8 ohm in PBTL.

An adjustable 50-300Hz low-pass filter with a 24dB/octave slope controls the bass range sent to your shaker, focusing on engines, explosions, impacts and cinematic bass while reducing unwanted higher-frequency vibration. Sources connect either by RCA from a TV, computer or audio player, or wirelessly via Bluetooth 5.3 from phones, tablets and computers, with Bluetooth reset supported for reconnection. Listed performance is 0.19% THD+N and 101dB-or-better SNR from a DC 15-24V supply - expect bass effects rather than audiophile music playback, since all outputs are intentionally limited to low frequencies. Optimized circuitry, upgraded heat dissipation and a compact aluminum chassis keep it stable during long sessions, and it fits beside your audio system, under a seat or in tight spaces.
