About: Eros Alto-Falante E18 Panzer 5.0K 18" 2500W RMS Speaker - 4 Ohms

Designed to work with very high power (5000 Watts) with large displacement of the mobile set, technology and a bold design. Panzer emerged to revolutionize and make history in the large subs market. It has a coil with a diameter of 134mm (5.3 inches), double centering with special treatment, providing greater stability with high power and a cellulose cone with long fibers, ensuring great performance at low frequencies and greater physical resistance. Due to the characteristics of the materials used and the diameter of the coil, it reproduces differentiated and unique subwoofer. It uses in its magnetic assembly a barium ferrite with a diameter of 280 mm, exclusive in our market, thus enabling a large mass of steel, providing better heat dissipation from the coil, thus reducing its dynamic compression. Available in 18 and 21 inches.
