KURZWEIL KS-40A Active pair of nearfield monitor

KS-40A Overview

Our motto, "It\'s The Sound" applies to not only keyboards, but to every step in the process of making music.... And so Kurzweil is pleased to present a new line of affordable, compact self-powered monitor speakers. The first model to be introduced, the KS-40A system, is a solid value, competing favorably with other monitors in and above its price range.

We believe the most accurate sound comes from the right combination of ingredients. Housed in a heavy, thick-walled, non-resonant wood cabinet, the KS-40A\'s sport a magnetically shielded, two-way, bass reflex design and a compact footprint.

Featuring a premium 3/4" dome tweeter and wide-range 4" woofer, 20Wrms system amplification and separate volume and bass adjustments, the KS-40A\'s are an ideal monitoring solution for the personal project studio or keyboard setup.

High frequencies are crisp and clear, low frequencies are balanced and warm, imparting a transparent sound to the KS-40A\'s with equal amounts of presence and clarity. For musicians who are on a budget but are unwilling to compromise when it comes to sound quality, the KS-40A\'s are the perfect compliment to our other affordable, high quality product lines like the SP and PC3LE series.

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

S2X

The S2X brings together the virtues of the ʽclassicalʼ 7” woofer and tweeter combination by using ADAM innovative technologies and top-class materials.

The HexaCone 7” woofer is driven by a sophisticated magnet system with a 2” voice coil creating a greater linear excursion. This produces more dynamics than one would assume in a monitor of such small proportions. As a result, in addition to the unsurpassed audio quality of the X-ART and A/B amplifier combination, this monitor surprises the listener with a very powerful, deep, but always tight and precise low end.

Review at a glance: "Sonic sensation“

“The ADAM Audio S2X can convince in all areas, concerning the sound as well as the workmanship, and are worth every Euro. […] a no-compromise tool for all who mean serious business, whether in music or postproductions.” (www.96kHz.de, 03/2010)

“We started off with a classical string quartet recording and let´s just say right away that the S2Xs floored us. Several adjectives spring to mind [...] - wide open, transparent, effortless, breathtaking realistic, loud, dynamic, involving... [...] If you close your eyes and continue listening, the S2Xs seem to ‚disappearʽ almost entirely. [...] you gradually become less aware that you´re listening to speakers because they´re like an open window on the music itself. [...] Result: These monitors are up there with the best we´ve tried so far.” (MusicTech, 01/2010)

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 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.
