The AMT-12 Lightweight Professional Loudspeaker is designed to deliver high-output music and sound reinforcement in a lightweight package. The 12-inch woofer has high sensitivity to maximize amplifier output. The 1.77-inch compression driver diaphragm, comprised of an titanium-alloy for added strength and rigidity, effortlessly handles the high input levels to match the woofer. A carefully designed cross-over network accurately filters each driver for proper matching of phase and summation in the cross-over region. The transition is much smoother than other loudspeakers in this class, making the sound more accurate and more realistic.
