Each cabinet contains two 12" bass drivers, two 6" mid range and a special horn loaded tweeter for additional sensitivity. The design incorporates perfect mechanical and electrical time alignment between the tweeter and the midrange units ensuring excellent off-axis response. The system is usually specified with a digital crossover system enabling perfect equalisation and correction. It is normally supplied as a two way active system with an integrated high efficiency passive network between mid and high.
