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 obtainable.
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
