PSB Speakers SubSeries 500 Subwoofer

A pair of air ports in this enormous Subseries 500 is placed at the bottom of the body. For their effective work the sub relies on two reliable supports, which also isolate the device from floor surface. High strength diffuser of 12-inch head is woven from fiberglass - light and material with necessary rigidity. Among the features of the driver we would like to note a large 50-mm sound coil and huge magnetic system with weight of about 2 kg. Circuit technique of the built-in amplifier is also very original. The developers define the class of its work as "H". In practice this means the usage of high-current field transistors together with high-effective pulse power supply unit. The potential of such combination in this case is up to 1,5 kW in peak.

Subseries 500 has just storm dynamics - few can compete with the sub on this indicator. There are no special claims to the relief of low frequencies too, but sometimes rhythm picture is a bit delayed. That's why the bursts of low-frequency energy can be transferred a little bit slower than usually. Despite of relatively large movable base, there are no problems here with fire rate. The depth of the played bass can be determined as really limitless that with the highest sound pressure requires a spacious room. Being armed with such a powerful energy, it needs equally massive partners, among which massive floor speaker systems should be at the first place.
