Hifonics ZXS700/4

Classic Zeus amplifiers have traditionally been analog and quite imposing. The large Zeus amps are still revered by car audio fans worldwide, but the downside of such behemoths is their significant space requirements in vehicles.

For this reason, the HiFonics engineers decided to utilize advanced digital power in the design of the new Zeus Street ZXS amplifiers, achieving ultra-compact heat sink dimensions. This is primarily made possible by modern Class D technology, which requires significantly less power—about 90% less—than comparably powerful analog amplifiers due to its extremely high efficiency. Another advantage is that the power supply cable cross-sections do not need to be as thick.

However, small does not mean weak: right from the first unboxing, it is clear that these are genuine Zeus amps. Despite their compact size, the models feel pleasantly heavy in hand, conveying a solid sense of the familiar HiFonics quality. Inset aluminum logo badges, carefully machined model numbers, and sophisticated aluminum die-cast end caps visually create a unique symbiosis of power and elegance that emanates from these amps.

All ZXS models, of course, come equipped with adjustable crossovers and the latest features, including an automatic turn-on function necessary for connecting to modern vehicle electronics. The high-level inputs are equipped with advanced EPS® technology to suppress error messages in vehicle diagnostic systems. Low-emission HiFonics IFT digital technology ensures uninterrupted radio reception.
