Driver: Twiggy12X4-470A (Twiggy12) — 12" Sub-woofer
Key T/S: Fs=30.0Hz, Qts=1.08, Vas=59.8L, Sens=84.2dB
Power: AES 200W / Cont 400W / Peak 800W
Xmax=9.25mm, Sd=506.7cm², Bl=9.9T·m
BH17 for hi-fi subwoofer systems, home theater, in-wall and under-seat installations, and similar domestic or automotive applications. It operates at 84.2 dB sensitivity (1W/1m). The driver features a compliant suspension design suited to moderate-volume enclosures with extended low-frequency response.
In a sealed enclosure, the driver is best suited to a net internal volume of approximately 20 liters, yielding an estimated –3 dB point of 60 Hz. The sealed alignment provides smooth, well-damped response with a predictable second-order roll-off below resonance, well suited to active crossover integration and DSP-controlled bass management.
The driver is intended for use with moderate amplification (approx. 200 W AES / 400 W continuous) and DSP control. A high-pass filter set at approximately 50 Hz is recommended to protect the driver below its usable range. Typical operating bandwidth is 60–100 Hz, making it suitable for integration with a mid-bass or full-range system.
This design is particularly effective in sealed enclosure systems used in hi-fi subwoofer systems, home theater, in-wall installations, automotive, and under-seat applications, where low-frequency extension and compact form factor are prioritized over high acoustic efficiency.
