ETON PRA 13 5 Inch 2-Way Component Car Speakers 60W RMS 3 Ohm
The ETON PRA 13 is a 5 inch (130 mm) 2-way component speaker set that brings German-engineered sound to the entry-level class. It's built around ETON's newly developed PRA cone technology: a rib-stiffened paper and fibreglass cone that is both very light and very rigid, which are the two basics of a good loudspeaker. The rib stiffening gives the cone maximum torsional rigidity for powerful, dynamic and precise bass.
The PRA series has a warm, full-bodied sound with rich vocals and impressive spatial depth. With a heavy-duty 3 ohm voice coil, the PRA 13 performs well straight off your factory radio or aftermarket head unit without an extra amplifier, making it an easy upgrade over tired factory speakers.
