Microspeakers to High-End Tweeters in Voice Coil May 2025

Voice Coil May 2025 is now available and in this issue, Vance Dickason explores the popular miniDSP Flex HTx processor, while Mike Klasco dives into the world of microspeakers. For this issue's Test Bench, Vance Dickason characterizes his first driver from the new Italian brand RS Speakers, a new TW 104.28 N/Ag 1.1” tweeter, and next measures the 27TFC/T 1” Soft Dome Tweeter from the SEAS Prestige Titan Line.

Sound Solutions International (SSI) introduced its latest family of high-performance microspeakers featuring improvements on loudness, linearity, and distortion levels by featuring the company's Coil-Anchor System (CAS) rocking suppression technology. The new microspeakers can easily scale for multiple applications and requirements in highly constrained mobile and portable designs. The patent-pending high-excursion Manticore speaker family already includes three models for smartphones and laptop/tablet applications.

The micro-acoustics experts at Sound Solutions Austria GmbH have developed a compact actuator that is able to ensure stereo sound quality when used to transform the display of increasingly thin smartphones and tablets into a loudspeaker. According to the Vienna-based company, the new “Singing Display” actuator is ideal for space-saving, waterproof designs, extending the response beyond what is possible with conventional speakers technologies, by being applied directly to the back of the large tablet or smartphone screen surfaces.
