The 4800 FR13 full-range speaker from Visaton provides uniform frequency response and a surprising amount of low-frequency output. The 1.25 Qts motor is designed to offer decent bass response when used in infinite baffle applications, such as automotive car door speakers, overhead public transportation systems, and is perfect for use in open baffle speakers. The dual-cone design offers seamless time alignment when compared to multi-way speakers, and simple installation is enabled by four open mounting tangs.
