Douk Audio G100 Bass Shaker Amplifier 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.

Specifications

How it compares

At $72.99 the G100 is the only amplifier in this group whose page lists Bluetooth (5.3, beside RCA). Its page says it is designed to drive the BS-1 and BS-2 shakers, and the Douk Audio BS-2 page names it as its match. It runs two shakers at 50W x 2 or one at 100W x 1 and ships with a DC 24V adapter. The Douk Audio BSA-600 costs $279.99, which is $207.00 more, and lists a 50-200Hz cutoff, 115W x 2 at 4Ω or 230W x 1 at 2Ω, a 5m wired remote and AC 100-240V input, with no Bluetooth; its page says it can drive up to 4 shakers in mono or 8 in stereo. The Nobsound NS-21G costs $39.99, which is $33.00 less, and is a mono 100W amp for 4-8Ω with a 20-160Hz low-pass filter, RCA and 3.5mm AUX inputs and a 19V adapter in the box, but no Bluetooth.

Who it suits: the G100 fits a desk, sofa or sim-rig build with one or two shakers fed from a phone or PC. Mind the figures: its 100W x 1 rating is given at 2Ω, so the page gives no single-shaker (PBTL) output at the 4Ω of a BS-2 or the 6Ω of a BS-1, and its 50W x 2 BTL rating is at 4Ω only. Skip it if you want to drive full-range speakers, since it is a bass amp built around a 50-300Hz low-pass filter. The Nobsound G2 PRO at $64.99, which is $8.00 less than the G100, is a mono 300W amp with a 40-300Hz cutoff, but that price is its option without a power adapter and its page lists no Bluetooth.
