The Eris E44 delivers an expanded and highly accurate frequency response and the widest stereo field available in its class. Its nested Midwoofer-Tweeter-Midwoofer (MTM, also known as “D’Appolito”) configuration offers improved off-axis response and spatial resolution. The result is a more consistent listening experience, smoother frequency response, and an ultra-wide, detailed stereo soundstage.
Sound waves radiating from the two components in a conventional speaker design can interfere with one another, creating peaks at some frequencies and dips at others, and these will vary depending on where the listener is relative to the speaker. In an MTM/D’Appolito configuration, component interference and the sonic inconsistencies that go with it are minimized. This affords listeners an ultra-wide sweet spot and a more consistent listening experience on- and off-axis.
Transparent and cohesive sound
The E44 utilizes a pair of 4.5", custom-woven, Kevlar low-frequency drivers. This provides a more-constant dispersion pattern throughout the frequency range, resulting in less time-smeared audio and cleaner overall sound. The weave and nature of the dual Kevlar woofers also helps break up reflected energy, so fewer delayed reflections reach the listener’s ear. In conjunction with the MTM/D’Appolito configuration, this helps create a transparent, cohesive sound.
Horizontal or vertical—it’s up to you
Many MTM configurations must be arrayed vertically, rather than horizontally, because vertical placement provides a clear, interference-free midrange and treble reproduction to either side, expanding the sweet spot. By bringing the midrange drivers closer together and raising the high-frequency driver, the E44 and E66 are able to perform optimally in both orientations. So, like all Eris speakers, the E44 and E66 let you position your speaker the way that works best for you.
You’re in control
Today’s music producers deal with a wide variety of musical genres and often work in more than one location. That’s why Eris-Series studio monitors offer extensive acoustic tuning controls. The three-position Acoustic Space switch helps to compensate for the boundary bass boost that can occur when a monitor is placed in a corner or near a wall. High and Mid controls help to further mitigate room anomalies. A Low Cutoff filter makes it easy to integrate a Temblor subwoofer into your monitor setup.
Like all PreSonus studio monitors, the Eris E44 offers consistent, accurate listening and extensive user controls. The ultra-wide stereo image afforded by its MTM/D’Appolito design makes it an ideal solution for anyone who requires best-in-class spatial resolution. Hear it at your favorite PreSonus dealer.

Comments about Presonus Eris E44 Active MTM Studio Monitor:
I purchased these monitors to replace the M-Audio BX5 Carbon-black studio monitors. I will not say anything bad about the BX5's as they were also great monitors, but there is something to be said about the MTM design concept. You can read about how good they are for hours and how there is no phase interference, but at the end of the day you really need to hear them to believe it. There is no sweet spot with these monitors. The phase alignment is so perfect that the angle at which you place these monitors is so forgiving.
I have these monitors paired with a PreSonus Temblor T10 sub woofer and sole use this setup for listening to music playback. I do not master and do any mixing through these speakers. All I can say is that they are so neutral and flat that without an EQ you can hear exactly what the studio was doing when they mastered the album you are listening to. These are phenomenal speakers for the money. Don't expect thumping bass out of these speakers though without a subwoofer. dual 4.5" MTM speakers have a total surface area of approx 32in^2. A single 8" speaker has a total of 50in^2. These will give a larger speaker a run for their money on volume and frequency response, but at the end of the day it still moves less air than a larger diameter speaker. The only advantage is that the E44s do extend down to the mid 40hz range. That is exceptionally low (good) response for 4.5" speakers.
Buy them you won't be disappointed. If you have the money, buy the E66 instead. If you really have the money, buy the scepters. If you're somewhere in between, stick with the R-series AMT models. They sound crystal clear with the air motion transformer style high frequency driver. The only thing I do not like about PreSonus's high end line of speakers is that they use a class "D" style amplifier instead of the class "A/B" switching amplifier. In my opinion class A while less efficient provides a better reproduction of sound. The downfall is more heat.
