The 4675 system pioneered new ground by being the first theater system to provide directivity matching between adjacent components at crossover. The system provided both uniform axial response and uniform power response from 200 Hz upward. The system was adopted as the first THX standard when Lucasfilm set up their THX theater certification program. Alternate versions are available, with and without passive networks. The model 4670 was developed later for those houses that lacked the behind-the-screen depth necessary for the 4675.

The 4645C subwoofer provides response down to 25 Hz with remarkably low distortion. Used in multiples, these units are responsible for the most awesome low end imaginable!

The surround models 8330 and 8340 represent ongoing efforts to provide a family of attractive, easy to mount surrounds that almost instantly became the favorite of both the professional film industry as well as the public exhibition industry. These products heralded in the era of “more but smaller” surrounds and have truly come into their own in today’s digital era.
