The Reps 1 represents state of the art in full range drivers. Precice machining with exceptionally tight tolerences and carefully chosen components have produced the finest full range driver ever. A new level of transparency and realism are now Reps R-1obtainable.

The Alcomax 5 magnet, in conjunction with the cobalt alloy pole cap, produces 20,000 Gauss and 100 dB/W at 1 m. This is the strongest type of alnico motor that can be reliably manufactured.

The voice coil is a most geometrically effective design. It is double wound and interleaved around one of the strongest papers available at only 0.075 mm ( 0.003" ) thick.

The cone, which is exceptionally light and rigid, is made of paper and specially treated for humid climates.

This type of design and construction assembled meticulously allows the driver to surpass all other designs.

The massive motor/low mass cone topology of the REPS R-1 faithfully reproduces the minute details of original music with less than five watts of input
