An Electro-Voice Speaker Designed for the Field, at the Heart of the EKX Range
The EKX series was designed to meet the demands of regular gigs: delivering professional-level performance, robust build quality, and easy setup. The EKX-15 fits this philosophy with a highly sought-after front-of-house format, capable of efficiently amplifying a band, event, or dance floor, while remaining portable and easy to rig or pole-mount.
Intended Uses and Users
The Electro-Voice EKX-15 is an ideal passive sound reinforcement speaker if you already have a suitable amplifier (or amplification rack) and are looking for a reliable system for stage and event use. It is particularly suited for mobile DJs, bands, multi-purpose rooms, service providers, and places of worship, where powerful, clear, and consistent sound coverage is a priority. Thanks to its extended response and high sound pressure level, it works very well in pairs for many setups and can also be paired with a subwoofer with appropriate filtering.
Performance, Dispersion, and Acoustic Design
With a max SPL of 132 dB, the EKX-15 aims for energetic reproduction without sacrificing intelligibility. Its frequency response covers the needs of a full-range speaker, with a clearly defined useful bandwidth according to standard thresholds (-3 dB and -10 dB). To optimize integration with a subwoofer, a recommended high-pass frequency of 50 Hz helps relieve the speaker from infrasonic content and increases headroom in the low spectrum.
EV Drivers and Titanium Driver
The 15-inch EVS-15M woofer provides the necessary foundation and impact, while the 1-inch titanium DH-1L tweeter delivers presence and detail in the highs. The 1.6 kHz crossover is calibrated for a coherent transition between low/mid and high frequencies to maintain a balanced sound at high volume.
SST Waveguide: More Consistent Coverage
The patented SST (Signal Synchronized Transducers) waveguide is designed to improve phase coherence and transducer synchronization, aiming for more uniform dispersion. The 90 deg x 60 deg dispersion facilitates front-of-house placement, especially when you need to cover a specific area while limiting side reflections.
Practicality: Mounting, Transport, and Integration
The 15 mm plywood enclosure with internal bracing is built to withstand touring rigors. The speaker features a 35 mm pole mount, a handle for easy handling, and 8 M10 rigging points for fixed or suspended installation. The 2 Speakon (NL4) connectors simplify cabling in professional environments, providing a reliable and secure connection.

Questions frequently asked
What amplifier power should be used with the Electro-Voice EKX-15?
This passive speaker has a nominal impedance of 8 ohms, with a minimum of 7.2 ohms. An amplifier compatible with 8 ohms is therefore required, but no specific amplification power is indicated.
Can the EKX-15 speaker be used without a subwoofer?
Its frequency response reaches 75 Hz at -3 dB and 50 Hz at -10 dB, allowing for full-range use. When used with a subwoofer, a high pass filter at 50 Hz is recommended to relieve the 15-inch driver.
What sound pressure level does this passive 15-inch speaker deliver?
The maximum declared sound pressure level is 132 dB, with an axial sensitivity of 96 dB. The 381 mm EVS-15M woofer is paired with a DH-1L 1-inch titanium diaphragm driver. Passive crossover occurs at 1.6 kHz.
What connections are available on this speaker?
Two Speakon NL4 connectors provide connection to the amplifier and facilitate daisy chaining in a sound system setup.
Can this speaker be mounted on a stand or suspended?
A 35 mm socket allows for stand mounting. Eight M10 suspension points are provided for flying installation, while the 15 mm plywood enclosure weighs 23.2 kg.
