HiFonics ZXT5000/1

With the ZEUS EXTREME ULTRA CLASS D series, HiFonics presents a particularly powerful line of amplifiers that combines state-of-the-art digital technology with enormous output power. The ZXT5000/1 was developed specifically for high-performance subwoofer systems and delivers an impressive 5,000 watts RMS into 1 ohm.

Thanks to advanced Ultra Class D technology, the monoblock achieves an efficiency of up to 93%. This means that a particularly large proportion of the input energy is converted into output power, while heat generation is reduced.

The ZXT5000/1 also impresses visually with a solid aluminum heat sink, precisely milled model designations, high-quality emblems, and sturdy aluminum end caps featuring the HiFonics logo. Screw-terminated RCA jacks, sealed power and speaker terminals, and an integrated clipping LED underscore its high-quality build.

An adjustable subsonic filter, a low-pass filter, and a variable bass boost are available for customizing the system to different subwoofer setups. A triple protection circuit further ensures the necessary operational safety.
