The SE1025R 4" 200W 2-way coaxial speakers are part of the SE Series range of speakers from Clarion. Clarion's SE Series enables you to enjoy powerful, dynamic sound with stable performance over a broad range from highs to lows, all in coaxial and multiaxial speakers design. These speakers are coaxial so the tweeter is built into the speaker design with the woofer, they do not need to be mounted separately. They are suitable for 4" installations. The MIPP cone woofer is designed for low distortion and high speed response, while the powerful strontium magnet produces dynamic bass response. These speakers are a great solution for replacing the factory OEM speakers in a vehicle.
