Ultra-wide, detailed stereo soundstage.
The Eris® E44 studio monitor delivers an
expanded, 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 oers
improved o-axis response and spatial resolution.
The result is a more consistent listening
experience, smoother frequency response, and
an ultra-wide, detailed stereo soundstage.
High dynamic output and detailed imaging.

Nested MTM 2-way
Conventional 2-way speaker
designs can cause significant
early reflections from their
surrounding environment. The
Eris E44 studio monitor
overcomes this by positioning
a 1.25-inch, silk dome
high-frequency driver between two 4.5-inch midrange drivers that
cover the same frequency range. The drivers are placed so that their
acoustic centers are less than one wavelength apart for any of the
frequencies they reproduce.
The combined signal of the two
relatively small drivers propagates
forward like a single waveform,
behaving like a single, larger driver.
This mutual coupling provides a
highly dynamic output in a compact
footprint. At the same time, the two
smaller woofers work in parallel
to partially contain the dispersion
of the tweeter, minimizing phase
displacement. The result is incredibly detailed stereo imaging.
Set up your studio monitors for your room.
PreSonus knows modern recording studios can be anywhere from
a spare bedroom to a multi-million dollar facility; that’s why every
studio monitor we make is equipped with controls that ensure the
flattest response in your mix environment. Acoustic tuning controls
allow you to configure the Eris E44 perfectly for your room—you
get Low-cut, Mid, and High controls, as well as 3-way acoustic
space tuning that allows you to easily compensate for the sonic
consequences of speaker placement against a wall or in a corner.
Accuracy dened.
The Eris E44 studio monitor oers consistent, accurate listening
and extensive user controls. The ultra-wide stereo image
aorded by its MTM/D’Appolito design makes it an ideal solution
for anyone who requires best-in-class spatial resolution.
