MUSWAY NX175.4 4-channel micro amplifier in Class D, 700 Watt RMS power, NX series

With the new NX series, Musway presents what is probably the most complete range of Class D micro-amplifiers to have appeared in recent years: twelve perfectly optimized models, built with exceptional construction care, offer the ideal solution for practically any application.

The distinctive feature of the NX series is its extremely compact design.

With a width of just 8.9 cm and a height of 4.1 cm, it completely redefines the performance of modern Class D micro-amplifiers. Never before has such power been packaged in such compact dimensions. Despite the compact size, each amplifier integrates cutting-edge Musway technology: from high-level inputs with EPS technology to complete crossover systems, everything is integrated into the unit. Even in this compact format, Musway enthusiasts do not have to forgo the attractive logo lighting, visible through a high-quality real glass window. On the sound quality front too, the Musway NX series sets new standards: thanks to extremely low distortion and careful tuning, it offers precise, dynamic and detailed musical reproduction.

The new 4-channel series combines extreme compactness with very high power density. The entry-level model is the NX125.4, capable of delivering 4 x 135 Watt RMS despite a chassis only 14.8 cm long. For higher power requirements, the NX175.4 and NX225.4 models are available. While offering impressive power, the top model stands out for its reduced size and includes a remote control for bass level adjustment. All amplifiers in the series are equipped with EPS technology and offer maximum flexibility thanks to integrated crossovers, characterized by an exceptionally wide adjustment range, from 50 to 5,000 Hz.

In issue 3/2026 of the magazine "Car & Hifi", the NX175.4 was subjected to the editorial team's rigorous tests. The result: maximum scores in every category. With measured power of 4 x 115 Watt at 4 Ohm and 191 Watt at 2 Ohm, the amplifier clearly exceeded the manufacturer's stated specifications. It received the exclusive SQ (Sound Quality) recommendation thanks to its exceptional audiophile performance. Topping off the test results was the "BEST PRODUCT" award, which establishes the NX175.4 as one of the best 4-channel amplifiers in its category.
