Product description
The PRA 10 speaker set from Eton stands out for its high-quality components and craftsmanship. Featuring a 100 mm (4 inch) woofer/midrange driver that uses a special paper-glass fiber diaphragm, it delivers outstanding sound quality. The powerful ferrite magnet ensures optimal cooling, while the aluminum dome tweeter with fabric surround provides the finest acoustic details. A high-performance 3-ohm voice coil enables maximum output even without an external amplifier. Additional features include the 12 dB inline crossover, various mounting housings, and a shallow installation depth of just 45 mm. Developed in Germany, the set offers a nominal power handling of 50 watts RMS and a music power handling of 80 W with a characteristic sound pressure of 90 dB.
