Electro-Voice Xcb Subwoofer

The Xcb is a manifolded, vented-box bass system utilizing one 457-mm (18-in.) woofer in the half-size X-Array™ enclosure shell. The one woofer faces into a slotted chamber at the bottom of the enclosure. This technique increases the acoustic loading, resulting in increased low-frequency efficiency (at slightly above box tuning) and reduced distortion compared to conventional direct-radiating designs. The woofers were designed as part of the Xcb development and represent a step forward in state-of-the-art loudspeaker design in terms of high acoustic output with low distortion and low power compression. Electro-Voice engineers developed a new technology dubbed Ring Mode Decoupling (RMD™) to substantially improve clarity and intelligibility by reducing both linear and nonlinear resonance modes that color the sound.

The low-frequency driver in the Xcb is the EVX-180B. An improved version of the industry- standard EVX-180A high-excursion 467-mm (18-in.) woofer that has distinguished itself as an industry standard for high-power, low-frequency reproduction. During the X-Array™ development, the thermal conduction of the motor was improved and the suspension was redesigned, giving the EVX-180B even lower power compression and a longer mechanical lifetime. In the Xcb, the woofer is slot-loaded in a vented enclosure optimized for maximized output from 37-160 Hz with minimized distortion. Ring Mode Decoupling, (RMD™), is a technique utilized and named by Electro-Voice to describe a process used to improve sound quality in loudspeaker systems.
