ERIS GETS TREATMENT FROM THE SHRINK
By Graeme Hague
16 December 2013
PreSonus has released an ultra-compact version of the new Eris monitors – and we’ve checked, stocks are available in Oz now. The Eris E4.5 studio reference monitor features (no surprise) a 4.5-inch, Kevlar low-frequency transducer, a 1-inch (25 mm), silk-dome, high-frequency tweeter, and a rear bass-reflect port. Each speaker is powered by a 25W Class AB amplifier, which is plenty for such a smaller format speaker and peak SPL is rated at 100 dB. The E4.5 ranges from 70 Hz up to 20 kHz, and at 6.42 x 9.45 x 7.09 inches (163 x 241 x 180 mm), it’ll just about fit into a Christmas stocking. The E4.5 is, obviously, designed for small home studio setups and mobile monitoring applications with balanced 6.5mm TRS and unbalanced RCA inputs, but additional unbalanced 3.5mm (1/8 inch) inputs make the E4.5 an option for replacing computer speakers driven direct from a motherboard, plus MP3 players, iPads and so on. A four-position Acoustic Space switch controls a second-order shelving filter, centred at 1 kHz, that provides three attenuation points (no attenuation, -2 dB, and -4 dB), allowing you to control the bass response. A High Pass switch sets the low-frequency cut-off (second-order slope, -12 dB/octave) to be flat, 80 Hz, or 100 Hz. You also get continuously adjustable (±6 dB) High Frequency and Midrange controls. All up, the Eris E4.5 is a true studio monitor with only one compromise – the size. Recommended retail price in Australia is $279 per pair.
