Tactile Bass You Can Feel: The Douk Audio BS-2 is a bass shaker / tactile transducer designed to turn low-frequency signals into physical vibration. Feel bass effects from games, movies, music, home theater and sim racing with an added layer of tactile impact beyond regular audio playback.
Efficient 30W Output: Rated at 30W power with 4Ω impedance, the BS-2 is built for efficient low-frequency performance. Its high-sensitivity structure helps deliver strong physical feedback when paired with the Douk Audio G100 or a compatible amplifier.
Engineered Internal Structure: Built with a high-strength ferrite magnet, precision voice coil, and optimized internal structure, the BS-2 responds quickly to low-frequency effects such as engines, explosions, impacts, and deep bass notes, making the feedback feel more direct and controlled.
Durable for Daily Use: The rigid aluminum housing helps resist heat, impact, and deformation while improving heat dissipation during extended sessions. Reliability testing for load, humidity, temperature, vibration, and drop performance helps support stable long-term use.
Flexible DIY Setup: Build your own tactile setup with one or multiple BS-2 units, and try different mounting positions to match your chair, sofa, bed frame, or platform. Different surfaces and locations can create different tactile effects, letting you explore the best tactile response.

FAQs

FAQs

Q: Can the BS-2 be used as a regular speaker?
A: No. It is designed for low-frequency tactile feedback, not full-range sound playback.
Q: What amplifier should I use with the BS-2?
A: Use a bass shaker amplifier or compatible subwoofer amp with low-pass filter, such as the Douk Audio G100. A regular 4Ω amp can also drive it, but the vibration effect may be less ideal with full-range signals.
Q: How much amplifier power is safe for the BS-2?
A: The BS-2 is rated at 30W, with 50W max input power and 4Ω impedance. Do not exceed 50W per unit. For long-term use, keeping output closer to 30W is recommended.
Q: Can I connect multiple BS-2 units together?
A: Yes, but total impedance changes with wiring. Two units in series equal about 8Ω, while two in parallel equal about 2Ω. Always confirm your amplifier supports the final impedance before use.

Q: Why isn't D1 syncing power on and off with my other devices via the 12V Trigger?
A: The D1's 12V Trigger uses a TRS connection. Please use a TRS cable (compatible with both TS and TRS jacks) to link to the trigger output of your other devices.

Q: Can I replace the op-amps in the D1？
A: Yes, the D1 uses 2PCs pluggable NE5532 op-amps, which can be replaced by normal dual op-amps like 2604/2134/muses02 etc. Before replacing, please turn off the power, ensure correct orientation, and power ononly after confirming proper installation.

Q: Why don't the single VU meter and spectrum display work properly?
A: In dual VU meter mode, both meters show the audio levels for the left and right channels separately.In single VU meter and spectrum modes, the D1 only detects the left channel input. If only the right channel is connected, the VU meter and spectrum display will not operate.

Q: Does the high-pass filter affect the Pre-Out signal?
A: No, the high-pass filter only applies to the speaker output. The Pre-Out delivers a full-range signal.

Q: Are the Pre-Out's volume and tone controls synchronized with the speaker output?
A: Yes.

Q: Is it normal for the D1 to become hot during operation?
A: The D1's TPA3255 amp chip dissipates heat through contact with the chassis. It is normal for the chassis to heat up during operation. This does not affect performance or lifespan of the D1. Please place the D1 in a well-ventilated area,and avoid stacking devices or blocking ventilation.

Q: What should I use the 12V trigger input for?
A: The 12V trigger input is designed for use with preamps or DACs that have a trigger output to achieve synchronous power on and off. Please do not use this port as an audio input or connect it to a power supply, as this could damage the D1.

Q: What is the required power supply for the D1?
A: The D1 requires a DC 24-48V (≥4A) input voltage. Please use the supplied power adapter for optimal performance. lf using a third-party power supply,ensure it meets the required voltage and current specifications.

Q: Why doesn't the remote control include batteries?
A: For safer and faster delivery, the remote control may not include batteries (AAA*2). Please prepare them yourself.
