Get the Latest on Cone and Diaphragm Technology with Voice Coil February

Voice Coil February 2019 is now available and features a Cone and Diaphragm Technology Focus, including an expanded directory of Loudspeaker Cone Industry Suppliers, and an updated directory of Headphone/Earphone Parts vendors - the first of its kind. In Acoustic Patents, James Croft discusses a new patent awarded to Polk Audio, updating the original Stereo Dimensional Array (SDA) loudspeaker with a new improved crosstalk cancellation version, and Vance Dickason characterizes the new Bold North Audio MS-10W woofer, a direct replacement for the famous white 6.5” driver on Yamaha’s NS10 studio monitors!

Home theater quality audio from a smartphone? Yes, it is possible to have an almost fully immersive experience, even from the limited speakers of a smartphone. Add a slightly better speaker, and the experience can be truly amazing, thanks to the Dirac Panorama Sound technology from audio signal processing experts Dirac Research. And now there is a commercial implementation of this mobile surround sound solution, integrated in the JBL Soundboost 2 speaker cover exclusively for Motorola moto z smartphones.

This is a dream project that’s been on the works for some time, and is now close to becoming a commercial reality. Combining all the possibilities of modern digital processing technology and electroacoustic design, Swiss companies Weiss and PSI Audio are promoting a fully working demonstration of the LiveBox fully-integrated Crosstalk Cancellation speaker, which allows both convincing stereo and binaural experiences from a single source, designed to be like “a piece of furniture.”
