The S1000 tweeters use Ring Radiator technology, an exclusive technology of ScanSpeak. It’s a non-dome-shaped soft diaphragm with a phase plug at its center and a large-scale roll. The phase plug prevents distortions from high-frequency collision and the Ring Radiator structure provides a high level of stability and high frequency band scalability. In result, you will hear more natural and clear sound.

Conventional speaker builds experience a struggle between the diaphragm of the driver unit and its enclosure. In order to get optimal performance, the faster a speaker diaphragm vibrates, a sturdier enclosure is required. Lighter weight enclosures can support the movement of a diaphragm, but sacrifice the acoustic performance due to the vibrations experienced, detracting from sound quality. The ACRO S1000 uses a sturdy aluminum alloy metal enclosure to withstand the fast vibrations of its diaphragm. The aluminum alloy minimizes noise and undesirable vibrations, leaving nothing but the air movements captured in your music. The S1000 enclosure not only provides acoustic benefits, but it completes the aesthetically pleasing design.
