KLH Model Seven

 The development of the Model Six has served as a valuable source of information for the design and construction of the Model Seven. Believing that a need exists for a loudspeaker system of about this size, the disign staff of KLH began the construction of prototype units using dynamic loudspeakers of various sizes and types. The system which resulted after a number of different units had been made and tested is now in production.

 The low frequency section of the Model Seven is a 12-inch acoustic suspension loudspeaker. The enclosure volume of 2,6 cu. Ft. Permits a very compliant moving system for extended low frequency response.

The high frequency section of the Model Seven consists of two small cone-type direct rediators operating as rigid pistons over a range from 1500 to 20,000 Hz. The use of two such loudspeakers gives a surprisingly large apparent sound source.

The low and high frequency sections are united by an LC crossover network, which establishes the crossover point at 1500 Hz. The relative levels of the low and high frequency section can be varied ±2,5 dB by means of a switch on the back of the enclosure. This provision is made to offer some degree of control over different room acoustics.
