The S4T compact, versatile speakers feature Near unique driver technologies to produce the highest sound quality in the most durable and reliable loudspeakers available. Precise sound reproduction is achieved with mid/bass drivers employing Near MDT and patented MLS technologies for superior sound and long-term durability. The high-frequency driver is a 1″ titanium diaphragm which perfectly complements the metal-alloy LF driver. A built-in 16W transformer (S4T) makes it compatible with 70V sound systems. The S4T speaker can switch between 70V or low-impedance systems by using a power tap selection switch. Near patented spiderless technology (MLS) and advanced materials deliver out-of-the-box performance year after year.
