ADAM | A77X | AX SERIES | 3-Way 2x7" & X-ART Tweeter | Studio Near Midfield Monitor
The AX-Series from ADAM Audio provides you with a wide range of monitors for different applications. Their excellent price-performance ratio makes them suitable for professional studio applications as well as upscale home recording.
Many technical innovations in ADAM’s high end SX-Series are also used in the AX models. The chamfered upper corners of the sturdy cabinet fronts minimise edge diffraction so that phase cancellation is not an issue. The speaker interior is equipped with a special fleece that prevents disturbing internal resonances as well as ensuring a better bass reflex tuning. The power switch and volume control are easily accessible on the front panel for greater ease of use. The front-firing bass ports are very useful as well, allowing the monitors to be set up closer to a wall if need be.
All models of the AX-Series feature two discrete amplifiers: an A/B amplifier that functions very quickly within its broad frequency range drives the X-ART tweeter. In the A5X, A7X, A8X and A77X monitors, the bass/mid- range woofers are each driven by powerful and highly efficient pulse-width modulated (PWM) amplifiers that do not require additional heat sinks and are more reliable and durable than other amplifiers.
The ‚Tweeter gain‘ function is a part of each AX monitor’s basic configuration and lets you raise or lower the level of the high frequencies by up to 4dB. Beyond that, shelving filters allow further adaptation to room acoustics with the A5X, A7X, A8X and A77X. The low shelf filter allows smooth control of the lower frequencies below 300 Hz from -6 dB to +6 dB, the high shelf EQ is introduced at 2.5 kHz with the same levels from -6 dB to +6 dB.
It goes without saying that all models of the AX-Series are equipped with ADAM’s X-ART tweeter that is handmade in Berlin. The tweeter works according to our proprietary X-ART principle, based on a slim, pleated foil working as the tweeter's diaphragm. The precise transient response and capability of reproducing the finest sonic details make the AX-Series monitors superior working tools.
The A77X is a horizontally designed monitor that combines all of the technical innovations in the AX-Series. Due to its powerful, compression-free sound reproduction and excellent radiation characteristics, it is suitable both for nearfield and midfield monitoring.
The special feature of the A77X is its 2 1⁄2-way system. Both 7” woofers start to work together at 38 Hz and at 400 Hz one woofer fades out and only the second woofer continues to operate in the midrange up to 3 kHz. This prevents interferences and possible phase cancellation in the critical midrange. Even though frequency transitions and potential distortions lie outside these areas, the human ear is particularly sensitive to midrange frequencies.
Especially noteworthy in the A77X is the extremely wide stereo foundation and brilliant stereo imaging. Treble and mids are reproduced with three-dimensional realism and the lows are, as expected from a double woofer design, massive without compromising on precision.
