The A4V is a two-way speaker incorporating a 4-inch long-throw woofer made from the same Multi-Layer Mineral (MLM) fibers as other A Series speakers plus the classic X-ART tweeter. Onboard DSP-based tuning capabilities let you easily dial in the perfect sound for your space.

With a frequency range of 52 Hz to 45 kHz, the A4V can accommodate a broad spectrum of audio applications—from producing podcasts to mixing string quartets—and will fit well within immersive and 3D setups.

“The new A4V studio monitor from ADAM Audio is a worthy entry-level model in the completely renewed A-Series, […]. Thanks to high-quality sound reproduction characteristics and contemporary DSP functionality with extensive control options – including compatibility with Sonarworks SoundID Reference – the A4V Monitor is a very hot tip among compact studio monitors!”

Peter Könemann

“The A4V nearfield speakers surprised us the most, as the […] speakers are true powerhouses and deliver an astonishingly deep and powerful bass for the size, which extends to 52Hz at –6dB measurement. We inevitably had a wow effect while listening and were really gobsmacked.”

BEAT Magazine

“They create far more bass than a little driver like that has any business creating […]”

Julian Rodgers
Pro Tools Expert

“Ahead of diving into the A Control and Room Adaptation modes, we were pretty impressed with the neutral quality of the speakers: nice, tight bass delivery coupled with clear and defined mids and tops.”

Mick Wilson
DJ Mag

“Anyone looking for nearfield monitors should definitely check out the ADAM Audio A4V. In the ADAM Audio A4V test, this earns the monitors an excellent rating without any deductions.”

Christoph Strauss

Limited Edition

On the occasion of the company's 25th anniversary, ADAM Audio is offering a limited edition run of the A4V studio monitors in arctic white.
