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“

The most powerful AX monitor

With its power and radiation characteristics, the brand new A8X is suitable for both nearfield and midfield monitoring. With a price/performance ratio that could hardly be better, this monitor is a perfect entry into these monitoring fields.

The A8X is equipped with the X-ART tweeter and a large (8.5”) midwoofer, a combination that adds both a very deep and yet very tight bass response to the unsurpassed reproduction qualities of the ADAM proprietary tweeter: a licence to thrill.

Cabinet- and bass reflex-construction

Like the other AX-Series models, the upper corners of the A8X are slanted to minimize reflections. The very large, double bass reflex tubes on the front have been specifically designed to perfectly match the midwoofer with its large voice coil.

Amplification and controls

With a 50W A/B amplifier for the tweeter and a 150W PWM amplifier for the midwoofer, the A8X has power in abundance and is the brawny monitor of the AX-Series.

On the rear panel are several controls: a gain for the high frequencies (± 4dB) and two shelf filters for the high and low frequencies.
There are both XLR (balanced) and RCA (unbalanced) connectors on the rear panel of the speaker, which allow the A8X to be used in almost any application.

Review: A8X: a "powerful link" between near- and midfield monitors!

"The A8X is a powerful link between ADAM´s AX Series and the formidable and more expensive SX Series. Its all-in-all homogenous tuning, the deep and precise bass as well as the brilliant mid- and high-frequency reproduction make this speaker a huge recommendation for ambitious people without deep pockets." (Professional Audio 10/2010)

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)

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 CMS 50 is the most compact monitoring loudspeaker of all the Focal Professional range. Its design permits listening from 50cm away, while still keeping the possibility of the monitors at a great distance from one another without damaging the soundstage. The 5” mid-woofer reaches down to 55Hz, while offering a controlled bass and a totally linear midrange. The midrange register of the CMS 50 has unequalled neutrality in its price range. The Al-Mg inverted dome tweeter offers outstanding dynamics and a degree of definition in the treble that allow precise measurement of reverb and other effects which are normally very difficult to assess.
