The ESB 3.6K2X is a two-way component speaker system from the Tremila series, designed to bring high-fidelity sound into your vehicle. This Italian-built set includes everything needed for a proper installation: a mid-woofer, a tweeter, and a passive crossover network with a 12dB slope that ensures each driver receives the correct frequency range. The audio experience is driven by the 3.165 mid-woofer, which features a 165 mm diameter and handles 120W RMS to provide solid low-end response. Complementing this is the 3.25 silk dome tweeter with a 25 mm size and 90W RMS power, which helps produce smooth, clear high frequencies without the harshness often found in metallic domes. Operating at a standard 4Ω impedance, these components are well-suited for car enthusiasts who want to upgrade their factory audio with a balanced system that blends powerful mid-bass with refined treble.
