Presonus Eris E3.5

The PreSonus Eris E3.5 is a pair of 3.5" 2-way 25W nearfield monitors designed to provide a compact sonic reference system for musicians, producers, and audio engineers in home setups, project studios, and commercial facilities.  The monitors can handle 105 dB maximum peak SPL. A rear bass-reflex port provides enhanced low-frequency range.

. 50  watts (25+25) class A/B amplification for tight bass and wide dynamic range.Two way design with 3.5 inch (76mm) woven composite low frequency tranducer and 1 inch(22mm) ultra low mas silk dome high frequency tranducer.

Each cabinet uses resonance-suppressing internal bracing to optimize the sound output and the amplifiers include RF interference, output-current limiting, over-temperature, transient, and subsonic protection circuits.
