PreSonus is now shipping its ultra-compact Eris E4.5 studio reference monitor/speaker, the third model in the Eris series of two-way monitor speakers. The monitor features a 4.5-inch, Kevlar low-frequency transducer, a 1-inch (25 millimeter), silk-dome, high-frequency tweeter and a rear bass-reflect port. Each speaker is powered by a 250-watt Class AB amplifier-plenty of juice for a small speaker. 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 millimeter), you can shoehorn it into almost any studio space.
The Eris E4.5 has balanced ¼” TRS and unbalanced RCA inputs, as well as unbalanced 1/8″ inputs for a smartphone or MP3 player. It also offers a four-position Acoustic Space switch controls a second-order shelving filter, centered at 1 kHz, that provides three attenuation points (no attenuation, -2 dB and -4 dB), allowing you to control the bass response relative to the wall proximity of your speakers. A High Pass switch sets the low-frequency cutoff (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.
This combination of controls lets you create a linear response for accurate monitoring. It also enables you to simulate different listening environments, so you don’t have to listen to mixes on your car, consumer computer speakers and home stereo to check how the music sounds with different systems. Instead, you can adjust the Eris monitors’ response and test your mixes without leaving your studio.
The Eris E4.5 lists for $199.95 a pair. Here are all the specs.
