Components
EV component woofers are high-efficiency designs highly
refined from years of development and field experience.
They employ extended-length voice coils for high-impact
reproduction of dynamic low-frequency program. All
woofers feature proprietary heat-transfer systems for
unmatched power capacity and reliability. Kevlar
® -fiber-
composite cones are used to provide structural strength to
resist collapse during explosive dynamic peaks and to pro-
vide internal mechanical damping to minimize resonances
that can change the character of the sound at high levels. DL
and EVX woofers are made of cast aluminium frames with
push terminals, and all feature Ring-Mode Decoupling™
(RMD™) except for the DL18MT and the EVX180B.
