PRESONUS Eris E-44 Studio Monitor ( Piece )

The Eris E44 and E66 deliver an expanded and highly accurate frequency response and the widest stereo field available in their class. Their 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.


Conventional 2-way designs can cause significant early reflections from their surrounding environment. The E44 and E66 overcome this by positioning a 1.25-inch, silk dome high-frequency driver between two 4.5-inch (E44) or 6.5-inch (E66) midrange drivers. 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.

The Genelec 8130A Digital Monitoring System has a 192 kHz/24 bit digital audio interface.
Due to its compact size, integrated construction, excellent dispersion and precise stereo
imaging, the 8130A is ideal for near field monitoring, mobile vans, digital audio workstations,
broadcast and TV control rooms, surround sound systems, home studios, multimedia
applications and also for use with computer soundcards. The Directivity Control Waveguide?
(DCW?) technology provides excellent frequency balance even in difficult acoustic
environments.
The integrated design allows the amplifiers and the drivers to be calibrated as a single unit,
eliminating the effects of component tolerances and ensuring consistent quality.
The all-aluminium Minimum Diffraction Enclosure? (MDE?) and advanced Directivity Control
Waveguide? (DCW?) technologies are carefully matched with advanced amplifier and electronics
circuitry. The low frequency response extends down to 55 Hz (-3 dB) while distortion is extremely
low due to a uniquely new rear reflex port design.
The 8130A has been specially designed to have a sufficient LF extension for most situations.
However if greater SPL's and a lower cutoff frequency are required, it can be complemented
with Genelec 7050B subwoofer.
The 8130A is very easy to set up and use, the only connections required are the mains supply
and the input signal. The female XLR input connector can be fed with either AES/EBU formatted
digital signal or analog line level audio signal. The Genelec 8130A automatically detects analog or
digital signals and directs them to the correct signal paths.

The Solo6 Be monitor will surprise you in the very first minutes you spend with it, partly due to its size/extended bass response (40Hz at -3dB). The 6.5" "W” composite sandwich mid-woofer combines neutrality in the midrange, fullness in the midbass register and bass control. Its compactness and the choice of a large front laminar port guarantee easy integration in studios that need a near field monitor without any acoustic compromise. The user settings on the back of the Solo6 Be, combined with its compactness, make it easy to carry and to adjust according to the acoustics of each studio.

PRICE PER UNIT

A revolutionary formula: 2 x 7 = 77

In some set-ups it can be advisable to use a horizontally designed speaker rather than a vertical one. Until now, such monitors were only available within the SX top line.

The brand new A77X, due to its outstanding features, might become a true game changer: Equipped with the same advanced technologies as the A7X, it therefore is very similar to the two-way speaker. The A77X, however, distinguishes itself by much higher, compression-free maximum sound pressure levels and dynamics. Due to its power and radiation characteristics, it also is perfectly suited for both near- and midfield monitoring.

Driver technology

Like all models of the AX series, the A77X features the ADAM proprietary X-ART tweeter. The ʽXʼ stands for ʽeXtended frequency responseʼ and thus for one of the features of the Accelerating Ribbon Technology that has been drastically improved: the frequency response. It now extends all the way up to 50kHz. In addition, the X-ART tweeter has higher efficiency and higher maximum sound pressure levels.

The two 7” woofers are identical with that of the A7X. With their large voice coils (1.5”) and powerful amplifiers, they are capable of both very high maximum sound pressure levels as well as very deep registers. The woofers do not cover the same frequency bands: while both of them are responsible for the (sub-) bass frequencies up to about 400Hz, only one of them reproduces the midrange. This prevents interferences between the two drivers. For stereo setups the A77X is available in A and B versions in order to guarantee a precise stereo image.

Amplifiers / controls

Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the bass-/midwoofers are driven by a 100W PWM amp each. The front panel includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.

The rear panel features several additional controls: a gain for the high frequencies (± 4dB) and two shelf filters for high and low frequencies.
To ensure greater compatibility, there are both XLR (balanced) and RCA (unbalanced) connectors.

Review samples:

“… a refreshing change“
"… if you liked the A7X youʼll like the A77X even more, and if the companyʼs smaller near-fields werenʼt your cup of tea, the A77X are definitely worth another listen. They are not much bigger than a two-driver cabinet design, so should slip into any installation where a near-field speaker will fit, but the extra low/ mid frequency drivers mean that the bass is more naturally extended and the mid-range clearer and more detailed. I like the A77X a lot and they make a refreshing change from the usual mid-priced near-field speakers." AUDIO MEDIA magazine / February 2012
