It has been for a long time that PureAudioProject has been working on their new three-way Open Baffle Speaker the Trio15 Coax10″.

“Trio15 Coax10″ was designed with music in mind, while pushing the sonic envelope of our popular Trio15 platform to the edge; It’s natural, smooth but at the same time fast and dynamic sound makes it a no-compromise high-end performer with any music genre,” says Ze’ev  Schlik, founder of the brand.
