The Reference Audio EOS 10000.4 delivers exceptional clarity and power in a compact Class-D design, making it a versatile solution for both daily drivers and competition systems. With 100W RMS x 4 @ 4Ω and up to 150W RMS x 4 @ 2Ω, this amplifier has the flexibility to power component splits, coaxial speakers, or run bridged at 330W x 2 @ 4Ω for stronger midbass or subwoofer applications.
Its 10Hz–40kHz frequency response ensures full-spectrum sound reproduction, while the 0.06% THD maintains audio precision even at high output levels. Built with efficiency in mind, the EOS 10000.4 runs at 90% efficiency @ 4Ω, keeping performance high and heat generation low.
The amp is protected by a full suite of safety features including thermal, overload, short circuit, and voltage input protection, along with a clipping LED indicator for safe, distortion-free operation. Despite its compact footprint of 180 x 42 x 176 mm, the EOS 10000.4 is engineered for serious audio builds that demand reliability and clean power delivery.
