At the heart of the PREMIUM PR:O full-range cabinets is a new 1" driver with ultra-low-distortion
that renders a very natural-sounding image even at peak loads. The 60° x 40° horn to which this
driver is coupled ensures uniform system directivity that is sure to delight performing musicians,
sound techs, and audiences alike.

Professional Features
The new PREMIUM PR:O series? high-value interior is reflected in the exterior?s smart appearance
and modern appointments. The ergonomically shaped and positioned handles are recessed into the
enclosures, with no projecting parts or screws that could ruin auto upholstery. In addition, the full-range
models feature countersunk rigging points for fast, professional fixed installation. For added convenience,
the subwoofer is pre-fitted with threaded bushings to accept optionally available casters. The ingeniously
simple DuoTilt? pole mount gives you a choice of angles at which to aim the speakers directly at your
audience, but without the hassle and risk of wobbly tilt units.

Dynamic protection circuit for the highfrequency driver
PREMIUM PR:O Series mid/high units and monitors are equipped with special protective circuitry.
Located in the high-frequency signal path, it limits output levels whenever the 1" driver approaches
the overload threshold.

PRICE PER UNIT

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."
