ESB Audio 5.6K3U — 3-Way Speaker System with UMA (no crossover) | HF Audio
5000 Series 3-way UMA system without crossover — for active DSP builds.
Built for the Passionate. Engineered for the Road. The ESB 5.6K3U is the 3-way UMA system without passive crossover — the choice for builders planning active DSP operation from day one. The 5.165 woofer and 5.UMA mid-high unit ship together; crossover duties are handled by a DSP processor like the Zapco DSP amplifier. Active operation eliminates passive crossover power loss and enables precise digital control of crossover frequency, slope, time alignment, and level — the reason dedicated SQ builders prefer it. The 5.6K3U gives you the drivers; the DSP gives you the control. Pair with a Zapco 4-channel DSP amplifier — the natural system partner for ESB 5000 Series in active configuration. Add the 5.6K3 CX crossover if you ever want to switch to passive operation.
