PreSonus is shipping the ultra-compact Eris E4.5 studio reference monitor, the third model in the Eris series of two-way monitor speakers announced one year ago, at the NAMM 2013. As with the Eris E5 and E8, the E4.5 can be user-adjusted to the acoustic space, allowing to create a more accurate listening environment or to simulate different common listening environments.

A four-position Acoustic Space switch controls a second-order shelving filter, centered at 1 kHz, providing three attenuation points (no attenuation, -2 dB, and -4 dB), allowing control of the bass response relative to the wall proximity. A High Pass switch sets the low-frequency cutoff (second-order slope, -12 dB/octave) to be flat, 80 Hz, or 100 Hz, with a continuously adjustable (±6 dB) High Frequency and Midrange controls, allowing a linear response for accurate monitoring.
This affordable new monitor speaker features balanced ¼” TRS, unbalanced RCA and unbalanced 1/8” inputs, being ideal for bedroom studios, school music programs, and as a high-quality replacement for computer speakers.
The Eris E4.5 features a 4.5-inch, Kevlar low-frequency transducer, a 1-inch (25 mm), silk-dome, high-frequency tweeter, and a rear bass-reflect port. A 25W Class AB amplifier powers each speaker, SPL is rated at 100 dB and frequency response is from 70 Hz up to 20 kHz.
The Eris E4.5 anticipated MAP/street price is $199.95/pair.
