ESB Audio 5.6K3UX — 3-Way Speaker System with UMA + Crossover | HF Audio
5000 Series 3-way system with UMA and crossover included. Complete Italian SQ package.
Built for the Passionate. Engineered for the Road. The ESB 5.6K3UX is the most complete package in the 5000 Series — a 3-way speaker system using the UMA integrated mid-high unit, packaged with the matched passive crossover network. Everything in one box: the 5.165 6.5" mid-woofer, the 5.UMA (2"/50 mm midrange dome + 1.1"/28 mm tweeter), and the 5.6K3 CX crossover. The 5000 Series was engineered with a clear mission: achieve maximum transient response by minimizing moving mass. Lighter, faster drivers that react instantly to the electrical signal from the amplifier produce a more realistic, more dynamic musical presentation. ESB achieved this by pairing a lightweight 6.5" woofer with a dome-format mid-high unit that moves with exceptional speed in the critical vocal frequency range. The UX designation means crossover included — no additional purchases needed. Install the 5.165 in the door, the 5.UMA at ear height, connect both to the 5.6K3 CX, and you have a reference-level 3-way Italian front stage ready to tune via DSP.
