High output and wireless adjustability

The Electro-Voice ZLX-15BT speakers feature their patented Signal Synchronized Transducer (SST) waveguide design for smooth response, consistent coverage, and low distortion. The heavy-duty polypropylene enclosure houses the EVS-15L 15" woofer and DH-1K titanium tweeter for clear, full-range sound, while its 1000-watt Class D power amplifier drives the speakers at up to 127 dB SPL for the kind of intensity that makes your sound come alive.

A single control knob gives you access to DSP processing, including 2-band EQ, selectable application modes (Music, Live, Speech, Club), and a limiter to keep your speakers safe at high levels. Five user-programmable presets help you save time by storing your favorite settings. A Sub/Top System Match feature optimizes this speaker's performance when paired with a subwoofer like EV's ELX200-12SP or ELX200-18SP

Versatile and tough

You'll also get two input channels with XLR/TRS jacks and individual level controls that allow you to adjust for line- or microphone-level signal sources, along with a 3.5mm AUX input for your portable devices. The ZLX-15BT's XLR output sends the combination of all input signals including Bluetooth (with a separate mix control) to a subwoofer or another speaker.

The rugged polypropylene enclosure is equally at home as a stage monitor angled up from the floor, a PA speaker mounted on a pole, or a hanging speaker suspended in a permanent installation. A powdercoated steel grille helps protect your investment from accidental damage. Three handles give crew members more carrying choices and make loading easier.

Product Research


Overview: The ZLX-15BT is a 2-way powered speaker for both portable and installed applications. It's comprised of a 15" woofer and a 1" titanium compression driver powered by a highly efficient Class-D power amplifier that can deliver up to 1000 watts of power with a maximum SPL of 127 dB. The ZLX-15BT offers 3 simultaneous inputs, including built-in Bluetooth for audio streaming. QuickSmart DSP which allows easy setup via four presets (Live, Music, Club, and Speech), along with sub/top system crossover settings, Bass & Treble settings, visual monitoring of limiter status, input level control with meters, and master volume control, all of which can be stored and recalled with five user-programmable presets.

SST: The ZLX-15BT uses EV's patented Signal Synchronized Transducers (SST) waveguide design that provides precise and consistent coverage, minimal distortion, and maximized acoustical loading. Drivers include a 15" woofer and a 1" EV DH-1K titanium compression driver that can provide up to 127dB of SPL from the built-in 1000W Class-D amplifier.

Built-In Bluetooth: The ZLX-15BT lets you stream music from your Bluetooth-enabled playback device, either for background music during performance breaks or for musical accompaniment during a performance.

Note: Bluetooth hands-free phone calls are not supported.

Rear Panel:

  • Inputs: The ZLX-15BT features two rear-panel input sections (along with Bluetooth streaming), each having a female combination XLR/1/4" (balanced) jack along with a corresponding rotary input level control. Both inputs can accept either Line- or Mic-level signals. Input 1 also includes a 3.5mm TRS (unbalanced) connection for plugging in a portable playback device.
  • Output: A male XLR jack is provided that can be used to output either a low-pass signal to a subwoofer, or a second powered PA speaker for stereo Bluetooth sound.
  • LCD Display: The rear panel also includes the LCD for the QuickSmart DSP menu along with a rotary dial that acts as a main volume control or, when pushed, will navigate through the menus.
  • Power: The ON/Off switch and IEC 3-pin power socket are located on the rear panel.

QuickSmart DSP: EV's proprietary QuickSmart DSP offers flexibility and ease of setup using the rear-panel LCD and control dial. DSP options include:

  • Mode: Allows selection of one of the four pre-configured presets: Music (default), Live, Speech, and Club.
  • Location: Determines the orientation of the PA speaker:
    • Pole (default): Used when the PA will be oriented in an upright position, either mounted to an optional stand (sold separately), or sitting on a stage or floor.
    • Monitor: Used when the PA speaker will be laying on its side as a floor monitor.
    • Bracket: Used when mounting the PA speaker to a wall using an optional bracket (sold separately).
  • Sub: The Sub menu can apply a high-pass filter to the speaker when used in conjunction with a subwoofer. Crossover options are: Off (Default), 80Hz, 100Hz, 120Hz, and 150Hz, as well as five additional choices for specific models of EV subwoofers. When the Crossover is on, low-frequencies will be outputted from the rear panel XLR Output jack.
  • Bass & Treble: A Treble applies a high-shelving filter that's centered at 6kHz, while the Bass setting provides a low-shelving filter centered at 60Hz. Both settings can be adjusted with +10 to -10dB of range. 
  • LED: This option determines if/when the front panel LED will light. Options are On, Off, and Limit. With this option the LED will light when the built-in limiter activates.
  • Display: The Display menu has three settings: Dim - determines if the display will dim after being idle for two minutes, Brightness, and Contrast.
  • Store/Recall: These two options allow the speaker's settings to be stored and recalled with 5 memory "slots" available.
  • Streaming: This option lets you Pair the PA speaker to your Bluetooth-enabled playback device.
  • Lock: The Lock option keeps the settings from inadvertently being changed.
  • Control App: This setting needs to be turned on if using EV's QuickSmart DSP app.
  • Reset: This option will restore all of the settings to the default selection.
  • Info: Shows product name and current firmware version.
