Emphaser ESW-M8 - 20cm Subwoofer

EMPHASER MONOLITH SUBWOOFER

“Turn up the volume!” This phrase, heard so often, expresses the clear desire not only to hear music, but also to want to hear it
really felt. The EMPHASER Monolith subwoofers give the music lover exactly what he wants in one
Moment required: a precise and powerful bass thunderstorm.
Whether installed in a compact closed box or in a level-proof bass reflex housing - the Monolith woofers are convincing
with their remarkable performance. The materials of the two Monolith subwoofer models were carefully selected and precisely matched to one another. Due to its hardness and high stability with low weight, the aluminum membrane is ideally suited for a detailed and extremely low-distortion reproduction in the intended area of application.

The low weight of the entire oscillating unit in connection with the powerful double magnet results in a considerable degree of efficiency.
The 4-layer voice coil made of copper wire, wound on a temperature-resistant polyimide carrier, ensures a high electrical load capacity. The Connex centering spider and butyl rubber surround, in turn, guarantee consistently high reproduction quality throughout the entire service life.
