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.
