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. Each monitor produces a frequency response of 80 Hz to 20 kHz via a 3.5" Kevlar woofer and a 1" silk dome tweeter powered by a 25W class AB amplifier. The monitors can handle 100 dB maximum peak SPL. A rear bass-reflex port provides enhanced low-frequency range.

For inputs, the monitor system accepts balanced 1/4" TRS, unbalanced 3.5mm, and unbalanced RCA inputs. An integrated 2-band AEQ allows you to fine tune the monitors to your listening preference. The AEQ controls include ±6 dB gain at 100 Hz and ±6 dB at 10 kHz. A front-panel 3.5mm stereo mini-jack is provided for easy headphone monitoring.

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

Overnight shipping will likely resume once things have returned to normal.

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

    Fantastic little speakers - I'm using them with a Roland FP 7 digital grand in conjunction with Pianoteq virtual grand piano software and they're ideal for my small studio. Highly recommended.
