The KEF Automotive Series was launched in 1985 with two alternatives for the person seeking ‘real’ in-car hi-fi. Both made a serious attempt to provide an even frequency balance in the vicinity of the driver’s head, when mounted either in door panels or rear window shelf, using the company’s unparalleled experience in controlling loudspeaker directivity.

 

The GT100 was a two-way plate system comprising a 114mm (4.5”) bass driver and 25mm (1”) soft domed tweeter.

 

The GT200 was a three-way system that combined the GT100 with rear enclosure and extra filtering with a coupled cavity subwoofer derived from technology developed for the Reference Series Model 104/2.
