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 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.
