The ESP-12 is a compact, versatile self-powered loudspeaker – delivering impressive output from a space-saving coaxial configuration. The ESP-12 is ideal for a wide variety of applications ranging from front-of-house duties to speech and music reinforcement, as a multi-purpose delay or fill speaker, or as a stage monitor. The onboard amplification and DSP package make the ESP-12 completely self-contained.

The ESP-12 is a two-way loudspeaker, using a 3” voice coil 12” (305mm) neodymium low frequency transducer and a 1.3” (33mm) exit coaxially-loaded high frequency transducer. The coaxial drive unit arrangement provides a uniform 80-degree conical dispersion pattern, with very smooth off-axis response and no parallax effects that would be present with separate LF and HF drive units. The result is a compact loudspeaker that provides excellent performance in a wide range of applications – from compact FOH use to powerful stage monitoring.

The ESP-12 utilises the latest in Class D amplifier technology, with a compact and lightweight module delivering a total power of 1200W RMS between the two drive units. Separate channels drive the low and high frequency transducers, allowing the ESP-12 to make the best use of the latest DSP for both performance as well as reliable limiting. The amplifier power supply is a universal voltage design, meaning the ESP-12 will operate happily across the globe. The amplifier is primarily passively cooled via the substantial heatsink on the rear of the enclosure, however for high temperature scenarios a fan is present within the loudspeaker itself to cool critical components in the high-demand scenarios. Four application-specific presets are available in the ESP-12 – for stand-alone use, flat response, use with a subwoofer, and stage monitoring. All functions are handled by the DSP including crossover, time alignment, and drive unit protection.
