FEATURES

• Image Control Waveguide:
  • The Image Control Waveguide was developed for JBL's new flagship M2 Master Reference Monitor and with the introduction of the JBL 3 Series, is now included for the first time in an affordable, compact reference monitor.
  • The patent-pending design of the Image Control Waveguide precisely controls the sound emanating from the speaker in the vertical and horizontal planes ensuring the presentation at the listening position is neutral and accurate.
• JBL Transducers are legendary for their performance. The 3 Series long-throw woofer and its damped woven composite Neodymium tweeter are designed from the ground up to reproduce the powerful transients and micro dynamics of your mix. These drivers deliver impressive deep bass and smooth high frequency response beyond the range of human hearing.
• JBL's Patented Slip StreamTM low frequency port design works in concert with the woofer to produce deep bass response at all playback levels. The double-flared shape of the port is precisely engineered for greater low-frequency extension and reduced turbulence.
• Big Power, Big Sound - 3 Series efficient Class D Amplifiers provide abundant power to deliver the output and dynamic headroom needed for the most demanding production styles
• Professional Balanced Inputs - Balanced XLR and 6 mm TRS inputs give you the options you need to connect your 3 Series to any signal source while maintaining professional signal quality.
• Selectable Input Sensitivity - The -10 dB/+4 dB sensitivity switch ensures compatibility with a broad range of signal sources, allowing you to connect the 3 Series to high output professional gear without any danger of input overload.
• LF Trim and HF Trim "TRIM" switches for both the Low and High Frequencies give you excellent control over the 3 Series sound in "your" room. Use these to fine-tune the amount of bass and treble you hear to compensate for room acoustics, program material and your personal taste.
• JBL Professional Reliability - Prior to becoming a production-ready design, each 3 Series model is subjected to JBL's tough 100 hour power test, in which the speaker is required to play continually at full output for 100 hours without failure. This demanding test ensures your 3 Series speakers will deliver years of reliable performance.
• JBL LSR Design - Your Music Needs a Point of Reference - While most manufacturers take only a single on axis measurement of the speaker's performance, this doesn't tell how it will sound in your room. JBL's LSR Linear Spatial Reference design criteria requires seventy-two measurements yielding more than 1,200 times more data, enabling JBL to engineer a speaker that "sounds right" in any working space. With LSR design, 3 Series Studio Monitors deliver superior accuracy regardless of the size and shape of your room, so your mixes "hit their mark" when heard on any playback system.

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 Twin6 Be is the best seller of the Focal Professional range and the most versatile work tool of the SM6 line. It represents the only necessary solution for recording, mixing and mastering. The image precision, treble definition as well as midrange neutrality are at the heart of its reputation.
The excellent articulation of the bass and midbass registers, even at very high sound levels, makes it an unavoidable reference for engineers who require absolute transparency. Furthermore, the design of the Twin6 Be permits a high SPL while at the same time offering a stable tonal balance. One of the two 6.5" woofers works in large band (midrange – bass) whereas the other reproduces from 40 to 150Hz. This creates a bass that preserves all the signal dynamics, without any masking effect in the midrange, thereby keeping all its neutrality and transparency. Additional control of the bass register is accomplished by fine-tuning on the control plate on the back of the Twin6 Be in order to obtain a perfect mirror configuration with its mate. The Twin6 Be can be installed vertically or horizontally to respond to the space requirements of each studio.

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)
