Last 2014 phonemaspeakers successfully launched Phonema KSP3 Speaker exclusively designed for Elecraft K3. Today Phonemaspeakers are proud to introduce Phits in the market: a new Phonema product designed to improve the acoustic quality of the speakers produced by major brands for radio amateurs. Phits is a set of acoustic foams that eliminate internal reverb and significantly improve sound quality and intelligibility. Phits is very simple to install and does not require modifying the original speaker. The result is amazing.
