Electro-Voice EKX-18SP - 18" Powered Subwoofer with QuickSmartDSP and Cardioid Control

The Electro-Voice EKX-18SP is an 18" powered subwoofer designed to deliver powerful, controlled bass to portable PA systems and fixed installations. Its 1300W Class D amplifier delivers up to 134dB SPL peak , while QuickSmartDSP processing with LCD display and a single encoder simplifies setup and control. It features Cardioid Control Technology , which when deployed multiple subs allows the energy to be directed towards the audience and up to 35dB of low end reduction on stage. The 15mm plywood enclosure with EVCoat , oversized slot-type ports and a double-barreled 18 AWG steel grille ensure robustness and low distortion. It offers two XLR/TRS combo inputs , two XLR link outputs for expansion, switchable low-pass filters (80/100/120/150 Hz) and an M20 thread for pole mounting full-range enclosures.
