Adrenalin for the ears Unique technology of high-end speakers paired with a newly developed tweeter, the RiCom SIGMA. An ultra-fast ring radiator with a flexible diaphragm which ist bended while moving. The quadral SIGNUM series not only impresses with its unique price/performance ratio, it also comes with all kinds of equipment.
