Powered 15" Subwoofer for Live Sound

The Electro-Voice EKX-15SP is an active subwoofer built for professional live sound reinforcement. It houses a 15 inch low-frequency driver powered by a 1300 Watt Class D amplifier. The system delivers a maximum sound pressure level of 133 dB across a frequency response of 40Hz to 180Hz. It suits engineers and venues needing deep, high-output bass in a self-contained unit.

Check Power and Rigging Before Ordering

Verify that your venue provides adequate mains power for the onboard amplifier and that your distribution can handle the draw. Confirm the enclosure weight of 74.0000 units is compatible with your transport cases, lifts or rigging points. Ensure you have the necessary signal cables to feed the subwoofer from your mixing console or processor. Cardioid Control Technology reduces rear radiation by up to 35dB, so plan placement to maximise this directional benefit.

Upgrades Passive Subs and Smaller Active Units

This model replaces passive subwoofers that require external rack amplifiers and crossover processing, simplifying the signal chain and reducing rack space. It also steps up from smaller-format active subs that cannot reach 133 dB SPL or the 40Hz low-frequency extension. The jump is worth it when you need cardioid steering for stage clarity, 15mm plywood durability for touring, and integrated thermal management for consistent output during long shows.

Questions about this item

What comes in the box with the EKX-15SP and what must I purchase separately?

The package contains the powered subwoofer with its built-in 1300W Class D amplifier. You will need to supply your own signal cables, a power cord if not included, and any mounting hardware such as a speaker pole for elevated placement.

How do I decide which version or capacity of the EKX-15SP to choose?

The EKX-15SP is offered as a single configuration: a 15-inch driver with a 1300W amplifier, 40Hz to 180Hz frequency response and a maximum SPL of 133dB. There are no alternative capacities or versions to select from.

What does the 133dB maximum SPL mean when the subwoofer is used in a real venue?

The 133dB peak output indicates the highest sound pressure level the subwoofer can produce at one metre. In practice this provides enough low-frequency headroom for large indoor or outdoor events, while Cardioid Control Technology reduces rear radiation by up to 35dB to keep stage sound clean.
