Acoustically Concealed Woofers (ACW™) Technology

Acoustically Concealed Woofers (ACW™) for controlled directivity down to low frequencies.

The 8351 Acoustically Coaxial Three-way system features our novel Acoustically Concealed Woofer (ACW™) technology. The Acoustically Concealed Woofers radiate through slots located on both ends of the enclosure.

The 8351 features two woofers and the positions of the two woofers have been chosen to extend the coaxial acoustical radiation concept towards low frequencies. In terms of low frequency directivity, when two woofers are used, separated by a distance, the system of two woofers behaves acoustically like one giant woofer spanning the distance between the two woofers. Also, such a dual woofer design extends the control of the directivity to low frequencies along the largest front baffle dimension.

The ACW technology makes the woofer openings and the woofer drivers acoustically invisible to the acoustical radiation from the minimum diffraction coaxial (MDC™) driver responsible for the midrange and tweeter frequencies. The radiation openings are optimized for size and curvature to minimize any acoustic diffractions.

The ACW solution also allows us to use the whole front baffle surface of the 8351 as one giant Directivity Control Waveguide (DCW™) that is part and built into a Minimum Diffraction Enclosure (MDE™).

The 8351 ACW arrangement creates a monitor that has a physically compact size yet behaves like a much larger system in terms of low frequency directivity.

Such controlled low frequency directivity translates to improved quality of monitoring and smaller low frequencies interaction between the monitor and the room.
