The Presonus Eris E4.5 is an active monitoring system, consisting of a pair of speakers, each equipped with a 4.5" woofer and 1" tweeter. This model bridges the gap between the ultra-compact Eris E3.5 and the larger and more extensively equipped Eris E5 (and Eris E5 XT). Like the rest of the range, the Eris E4.5 is a well-balanced and natural-sounding monitor, especially given its price. Dedicated filters allow the basic sound of the Eris E4.5 to be easily adapted to different room acoustics, and the Eris 4.5 BT model features additional Bluetooth connectivity.
The Presonus Eris E4.5 is fitted with a carefully designed and solidly built bass reflex cabinet made of vinyl-laminated MDF. As with all the Eris models, the woofers are made of Kevlar, producing a clean and precise bass response and even diffusion through all the lower frequencies (here from 70 Hz upwards). Similarly, the silk dome tweeter reproduces all the high frequencies in a very natural way and provides a wide sweet spot in the listening position. Each speaker is powered by a 25-watt class AB amplifier, and both amplifiers are located in the left speaker, the front panel of which also features a convenient headphone output.
The Presonus Eris E4.5 is aimed at anyone looking for a reliable and affordable studio monitor. The speaker's compact dimensions will look great in the minimalist spaces often used by YouTubers and podcasters, or anyone else producing audio and video material at home. The speaker will adapt very easily to the acoustic conditions of these rooms thanks to two shelving filters which respectively handle the bass and treble frequencies (each by +/- 6 dB). For music (or even multimedia) production, we recommend using the Eris E4.5 in combination with an active subwoofer, such as the Temblor T8 from the same manufacturer, in order to properly control the low end of the spectrum.
Presonus is a US company founded in 1995 by Jim Odom and Brian Smith in Baton Rouge, Lousiana. The firm designs hardware and software at both professional and more affordable levels for musicians and producers. Presonus first made a splash in the mid-1990s with the DCP8, an eight-channel analogue compressor/limiter/gate with fader and mute automation that could be digitally controlled by MIDI. In the early 2000s followed a series of microphone amplifiers and the first audio interfaces for the then-emerging home studio scene. Today, the company's product range includes audio interfaces, microphone preamps, digital mixing consoles, and studio monitors as well as the established DAW software Studio One.
The Presonus Eris E4.5 can be connected to the outputs of an audio interface (or subwoofer) via its 6.3 mm balanced jacks. Both inputs are located on the left speaker, itself connected to the right speaker via the provided cable. In addition, the Eris E4.5 features unbalanced RCA inputs, calibrated to -10 dBV, thus allowing home hi-fi equipment, for example, to be connected. Finally, an auxiliary 3.5 jack stereo input, located on the front panel, is also provided to easily connect all kinds of audio players, including smartphones.
