The R-6 is a very unique car speaker system.  Our engineers took our popular 6" double magnet woofer and integrated a 28mm (1.1) semi-horn soft dome tweeter resulting in a special full-range speaker with a triple magnet motor system.  The tweeter also utilizes the motor system cavity as its acoustic chamber.  It is a very compact and shallow driver, enabling it to be mounted easily in the door, rear deck or kick panel of any car.  This is not your conventional co-axial speaker.  It sounds and performs better than any other co-axial system on the market.   The sound stage and focus of the R-6 is very natural.  The midbass, midrange and highs are clear and smooth.  This system is based on the original Integra that was introduced in the United States by morel usa about 20 years ago.
