The Boschmann XJ3-443B is a pair of 4-inch full-range coaxial 3-way loudspeakers from the XJ3 Premium Line, designed to bring a balanced audio experience to your vehicle. These speakers handle a continuous RMS rating of 90 Watts and can reach a maximum power of 270 Watts, making them compatible with amplifiers ranging from 5 to 90 Watts per channel. They cover a frequency response from 60Hz to 22,000Hz, ensuring that both deep tones and high notes are captured clearly. Built for quality sound reproduction, the design features a 23mm midrange diaphragm and an 18mm tweeter with a silicon oxygen tetra-hedra core for precise high frequencies. The internal BM Audio self-stabilizing shock-absorbent magnet design helps maintain stability, while gold-plated terminals ensure a clean signal for a pure bass response. Each unit weighs 545 grams and has a mounting depth of 50mm, with a maximum outside diameter of 100mm. Installation is straightforward thanks to the 82.5mm x 115mm mounting points, though you will need 10mm of clearance above the surface for the tweeter protrusion. The set comes ready for your car's audio upgrade, including the two speakers, protective covers, necessary wiring, and screws, all secured in protective cardboard molded packaging.
