The Reference Audio EOS 12000.4 pushes the boundaries of compact amplifier engineering by combining
big power with
small size. With an output of
120W x 4 @ 4Ω and up to
200W x 4 @ 2Ω, it offers plenty of headroom for powering high-performance component splits, coaxials, or bridging to
430W x 2 @ 4Ω for subwoofers or midbass drivers.
Designed for accuracy as much as power, it features a
high damping factor of 150, ensuring tight cone control and reduced distortion for clean, dynamic audio reproduction. Its
wide frequency response (10Hz–31kHz) makes it suitable for both full-range and specialized applications, while the
adjustable crossovers and subsonic filter (20Hz–3kHz) provide precise tuning options for any system setup.
Built with a
90% efficiency rating, the EOS 12000.4 runs cool and conserves energy, while the
comprehensive protection suite (thermal, overload, short circuit, and voltage input) guarantees long-term durability. Despite its
compact chassis (180 x 55 x 178 mm), it delivers competition-grade performance with a
clipping protection LED to safeguard your system at high levels.
The EOS 12000.4 is the amplifier of choice for those who need
flexibility, power, and clarity in a sleek, compact package that doesn’t compromise on performance.
