The JBL VTX V20 is an ultra-compact active 3-way speaker system that delivers unprecedented performance in its class, offering remarkably well-articulated, neutral and extended frequency response. Its innovative suspension system supports low frequency reproduction to 40 Hz without compromise. The highly efficient 2.5″ (64 mm) composite driver unit in the high power bass woofer features a proprietary rubber surround for enhanced linearity and improved high-frequency performance in the mid and high bass bands. The JBL VTX V20’s 1″ (25 mm) polymer/ silk dome tweeter’s advanced waveguide design provides excellent on and off axis frequency response as well. This powerful small box features the same engineering that made the VTX V25 so critically acclaimed.
