The Boschmann XR-4836 is a set of 3-way coaxial car audio speakers designed to bring balanced sound to your vehicle's interior. These 4-inch drivers deliver a peak power of 270 Watts and a continuous RMS rating of 90 Watts, making them compatible with amplifiers providing between 5 and 90 Watts per channel. They cover a frequency range from 60Hz up to 22,000Hz with a sensitivity of 90dB, ensuring that both low-end tones and high frequencies remain clear. Construction focuses on durability and signal purity, featuring a polypropylene injection molded woofer and silicon oxygen tetra-hedra core high frequency dome drivers for the tweeters. To maintain a strong connection without signal loss, the speakers use gold-plated pure brass terminals and a self-stabilizing shock absorbent magnet design. Each unit weighs 525 grams and requires a mounting depth of 49mm, fitting into spaces with mounting points measuring 115mm by 80mm. The set comes in retail packaging with cardboard protection and includes the two speakers, matching covers, and necessary speaker wire. Because of their compact 100mm diameter and efficient power handling, these are a practical choice for drivers looking to upgrade their factory audio system without needing extensive modifications to the door or dashboard panels.
