PreSonus® Eris®-series studio monitors are used worldwide by audio engineers who need to hear every detail of their recordings. Ideal for gaming and home video production, the Eris E4.5 BT employs the same technology as the larger Eris models to deliver studio-quality sound, with a smooth and accurate frequency response. Yet they’re compact enough to fit almost anywhere.
Clean overall sound, smooth high end, and a wide sweet spot
Every Eris-series studio monitor utilizes a woven composite low-frequency driver. The weave and nature of the Eris E4.5 BT’s 4.5-inch woofer result in tight bass that you can feel, as well as cleaner overall sound. The one-inch silk-dome tweeter produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide pattern, creating a large optimal listening area, or “sweet spot,” so you can move around and still hear an accurate stereo image. With 25 watts per side of onboard power, the Eris BT-series monitor speakers pack a serious punch, while still delivering clear, accurate audio.
Easy-to-use controls.
A speaker’s response is affected by where you place it and the acoustics of your space. That’s why Eris E4.5 BT active media reference monitors offer controls to adjust the high- and low-frequency content, ensuring that your Bluetooth speakers always sound their best. A convenient front-panel volume knob sets both the speaker level and the integrated headphone amplifier’s level.
Convenient wireless Bluetooth connectivity.
With four different types of audio inputs, it’s easy to feed audio to your Eris E4.5 BT monitors from almost any source. Fast, reliable, stereo Bluetooth 5.0 connectivity lets you go wireless, streaming sound from a smartphone, tablet, laptop, or other Bluetooth source. Play games, listen to music, and even create content wirelessly. When you want a wired connection—say, from a computer, turntable, TV, or other line-level source—the Eris E4.5 BT has you covered, with rear-panel, left and right ¼-inch TRS and RCA inputs and front-panel 1/8” stereo inputs. A loud, clear, front-panel headphone amplifier lets you work and play in stealth mode, without disturbing your housemates.
Accuracy defined.
Like all PreSonus speakers, the Eris E4.5 BT offers consistent, accurate listening, with the smooth and even frequency response that has made Eris studio and media reference monitors popular around the world. Their compact and powerful design makes them an ideal solution for any small space. Want extra-deep low end?

The original A5
The small A5 managed to make itself a big name in both professional environments as well as in computer or desktop applications. A wealth of truly outstanding reviews and many awards helped to establish this speaker as one "of the best small monitors” and a "great choice for the small studio.” (Future Music, 01/2009).
The new A5X
The similar dimensions and name could make one believe that the A5X is nothing more than a new version of the A5. A quick listening however leaves no doubt that the A5X is much more than that.
Like all other models of the AX-Series it features the proprietary X-ART tweeter. The very data of this technology shows that it is at the forefront of what tweeters can accomplish. Numerous listening tests have confirmed this.
A 5.5” Midwoofer reproduces the frequencies below 2.5kHz. The diaphragm is made from Carbon fiber/Rohacell/Glass fiber, which is the same composite structure shared in the next two bigger models. This material with minimum weight and maximum rigidity prevents break up resonances, resulting in an outstanding dynamic behaviour and impeccable sound characteristics.
Stereolink
A very handy and exclusive feature found in the two smaller AX monitors is the Stereolink. This is accomplished by a pair of additional RCA connections that allow for a bypass of the second stereo channel to the other speaker.
This new technology connects two A5X speakers in such a manner as to allow the user the option to control the overall stereo volume of the system from either speakers gain control. This makes the A5X a natural for "mixer-less” desktop applications where overall system volume needs to be adjusted easily.
Controls and Connectors
The front of the A5X sports dual ports for surprisingly low frequency response down to 50Hz. The front panel also has power and gain controls. The rear panel includes a tweeter gain control as well as balanced (XLR) jacks and unbalanced (RCA) jacks, allowing for greater connection flexibility. There are also two M6 (6 mm) metric screw threads for stand/wall mounting.
Review: "The A5X: a superb impression.“
"A sparkling and lively desktop monitor with an open, powerful character. Good filters and practical ergonomics as well as useful equipment make ADAMs A5X an ideal partner in multimedia nearfield sound." (Stereo, 10/10)

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
“… wide and spacious soundstage with solid left/right imaging“ "… they are fun and easy to work with, covering all the essential functions required of high-end monitors with aplomb." MusicTech magazine / April 2012
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.
