- Shallow, yet high cone excursion
- Honeycomb cone
- Ideal for 4x4” wall subwoofer, car underseat subwoofers
- The ultimate in shallow depth woofer design! We created this powerhouse of a speaker with limited spaces in mind, allowing you to fit it into the most compact areas while still delivering massive low frequencies. The extreme shallowness of the Twiggy 12 opens up a world of possibilities, allowing designers to craft enclosures that seamlessly integrate into typical 4x4" wall structures, under vehicle seats, beneath sofas,and more. But don't
- be fooled by its shallow design –the cone excursion approaches an impressive 22.4mm peak to peak, ensuring that this woofer will deliver sizable amounts of low frequencies without compromising on performance. The cone is constructed with a honeycomb structure and layers of woven glass fibers, adding not only to its strength but also to the overall rigidity and performance.Our patented design guarantees that the
- depth versus cone excursion ratio is the best available in the market, ensuring optimal sound quality in any installation. The unique magnetic structure of the Twiggy 12 delivers a high-strength B field with minimal distortion artifacts, further enhancing the audio experience.To top it off, this little powerhouse can handle up to 800 watts of peak power amplification, making it the go-to choice for delivering excelent sound experience.

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.
