Adam Audio A4V, 4-inch Powered Studio Monitor

The Adam Audio A4V, 4-inch Powered Studio Monitor is a high-quality, compact two-way studio monitor designed for nearfield use in both stereo and multichannel audio environments. Featuring a 4-inch long-throw woofer constructed from Multi-Layer Mineral (MLM) fibers and the renowned German Handmade X-ART tweeter, the A4V delivers clarity, precision, and deep detail across a wide frequency range. The monitor’s onboard DSP-based tuning allows for precise room adaptation, while its compact size makes it ideal for smaller control rooms, desktop workstations, or immersive setups. Whether you're mixing orchestral music, editing audio for video, or producing podcasts, the A4V provides unmatched accuracy in a small footprint.

Explore the Technology

ADAM Audio monitors have earned a worldwide reputation for the innovations that we have established in the field of loudspeaker technology. Here you can explore the technology of the A4V.

A Control Remote Software

The DSP-based functionality of all A Series monitors can be controlled remotely and in real time over ethernet using A Control.

Rotatable HPS Waveguide & X-ART Tweeter

Made from a new glass fiber polymer compound, the HPS waveguide enables the X-ART tweeter to disperse sound in space with controlled consistency.

Bass Reflex System, Cabinets and Mounting

The new A Series cabinet build on the heritage of ADAM Audio and the AX Series in particular.

Automated Room Correction with Sonarworks

ADAM Audio is proud to partner with Sonarworks on an automated room correction solution that runs directly on the DSP of A Series monitors.

Hybrid Amplification

The A Series combines the best of both digital and analog worlds.

Multi-Layer Mineral Woofer [MLM]

The latest materials and advanced analysis and design processes have led to the development of our new long-throw woofers.

Midrange Driver

A Series midrange driver deliver clean sound in the critical part of the frequency range where humans are especially sensitive to coloration of sound.

Voicings

A “Voicing” is a pre-defined sound profile of an A Series monitor. On the back panel, you will find two different selections, “UNR” and “Pure”.

Room Adaptation

On the back panel of A Series speakers, you will find four bands of room adaptation equalization Bass, Desk, Presence and Treble.

Digital Signal Processing

The A Series capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision than analog-only speakers.
