EKX-18SP

▪ QuickSmartDSP features best-in-class processing,

EV’s signature single-knob user interface, and
intuitive menu navigation via LCD.

▪ Cardioid Control Technology allows output to be

steered towards the audience with up to 35 dB
reduction on stage when multiple subs are
deployed.

▪ High-efficiency 1300 W Class-D power amplifier

delivers up to 134 dB SPL utilizing high-sensitivity
transducers designed and engineered by EV.

▪ Intelligent thermal management with a

variable-speed fan controlled by multiple onboard
sensors.

▪ Two (2) XLR outputs for easy system expansion to

additional loudspeakers or subwoofers. Large slot
ports for low distortion and excellent bass
extension. Two (2) metal grille reinforcement bar.
M20 threaded pole mount plate.

EKX-18SP features high-efficiency Class-D power
amplifiers (up to 1300 W) with integrated
QuickSmartDSP, and delivers up to 134 dB SPL
utilizing high-sensitivity transducers designed and
engineered by EV (18-inch EVS-18C subwoofer).
The EKX amplifier incorporates intelligent thermal
management (with a variable-speed fan controlled by
multiple onboard sensors) which ensures superior
performance and reliability in demanding
environmental conditions.
Powered subwoofer models allow easy setup via three
(3) presets (Music, Live, Club), sub/top
system-match crossovers, five (5) user-programmable
presets (Store and Recall settings), visual monitoring
of limiter status, input level meters, and master
volume control to ensure optimal gain structure.
Adapted from our touring systems, EV’s exclusive
Cardioid Control Technology allows output to be
steered towards the audience with up to 35 dB
reduction on stage when multiple subs are deployed.

EKX powered models are ideal for portable and
installed applications, with lightweight and compact
15-mm wood enclosures with internal bracing, durable
EVCoat finish, aluminum pole-mounts, and all-metal
handles.
