Adam A77X Active Studio Monitor, Left - Box Opened

The Adam A77X Active Studio Monitor, Left is a premium-quality studio reference monitor featuring 2 x 100W 7'' carbon subwoofers and a single 50W X-Art Tweeter as well as a built-in control panel for input sensitivity. This particular version of the Adam A77X has been tuned to be positioning on the left side of your listening range, giving you an enhanced stereo field when used in pairs. The horizontal design delivers compression-free performance and optimal audio quality for mixing and mastering applications. The unique 2 1/2?? system utilises two woofers that work together around the 38Hz mark, with the second woofer operating up to 3 Khz for optimal audio performance. This design helps to eliminate interference and phase cancellation in the midrange as well as improving the overall performance value and audio quality.

Please note, the box has been opened as part of our quality control inspections and as such all the seals have been broken. The item itself is brand new and has never been used.

This is a great opportunity to buy a fully functioning product at a discounted price, supplied with a one year warranty.

Sophisticated Design

The AX series monitor cabinets feature chambered upper corners on the front, helping to minimise edge diffraction so that phase cancellation is not an issue. The interior of the cabinet is equipped with a special fleece that prevents the internal resonances being disturbed as well as ensuring superior bass reflex tuning. The front panel houses the power switch, volume control and front-firing bass reflex ports, providing greater ease of use and allowing the monitor to be placed closer to a wall if needed.

The woofers on all AX series monitors are built using a construction of woven carbon and glass fiber with the synthetic material Rohacell. When these three materials are combined together, the result is an ultra-lightweight yet extremely rigid material that provides excellent transient responses.

Driver technology

Like all models of the AX series, the A77X features the ADAM proprietary X-ART tweeter. The "X" stands for "eXtended frequency response" 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 one of them is responsible for the (sub-) bass frequencies up to about 400Hz, the other takes over most of the midrange.

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.
