Douk Audio BS-2 30W Bass Shaker

Features: 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. 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. Parameters Brand: Douk Audio Model: BS-2 Rated Impedance: 4Ω ±15% Rated Input Power: 30W Max.
