The EON Power15 is a powerful, full-range speaker system incorporating a discrete 130 watt power amplifier for the low frequency section and a monolithic 50 watt power amplifier for the high frequency driver. The system is a light weight, rugged, roadworthy speaker enclosure that incorporates an aluminum die-cast baffle and a structural polypropylene enclosure designed for portable applications. Careful attention has been paid to ensure that the overall system frequency response remains smooth and consistent both on and off axis, which is essential for good articulation and accurate reproduction of speech.
