ESB Audio 3.6K3U — 3-Way Speaker System (3.165 + 3.UMA) | HF Audio
3000 Series 3-way UMA system. Italian SQ performance at an accessible price.
Built for the Passionate. Engineered for the Road. The ESB 3.6K3U is the UMA-configured 3-way system from the 3000 Series — the 3.165 6.5" mid-woofer paired with the 3.UMA integrated mid-high unit (2.5"/65 mm midrange + 1"/25 mm tweeter). The 3000 Series is where ESB's research-level engineering meets an accessible price point — Y-35 grade ferrite magnets, waterproof-treated pressed paper cones, and silk dome tweeters with iron-fluid damped voice coils. The 3000 Series was developed with a genuine commitment to material and engineering research — ESB's own characterization, and one backed by the build quality visible when you hold these drivers. The basket geometry, cone treatment, and voice coil design all reflect serious development work, not cost-cutting. A 3-way system at this price level that uses real Italian engineering is rare. The 3.6K3U is the front stage upgrade that changes what daily drivers expect from their car audio.
