The ESP-15S is a compact, versatile self-powered subwoofer, designed to complement the ESP-8 and ESP-12 self-powered loudspeakers for applications ranging from live music to corporate and audio-visual. The onboard amplification and DSP package make the ESP-15S completely self-contained.
The ESP-15S is a compact reflex-loaded powered subwoofer using a single 4” (101.6mm) voice coil 15” (381mm) low frequency transducer, and is designed to complement and provide extended low frequency response for the ESP-8 and ESP-12 compact coaxial powered loudspeakers.
The ESP-15S utilises the latest in Class D amplifier technology, with a compact and lightweight module delivering a total power of 1200W RMS to the single drive unit. The amplifier power supply is a universal voltage design, meaning the ESP-15S 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 presets are available in the ESP-15S – each one with a different low pass filter frequency to enable the user to tailor the characteristics of the subwoofer to their personal taste.
