Phonema insulation kits for speakers

Phonema supplies accurately fitting insulation materials for various loudspeaker models of the manufacturers Icom, Kenwood and Yaesu. These desktop speakers are matching in design and size for various desktop radios, and leave some room for improvement concerning the quality of the sound. The kits are very helpful in shaping the internal resonance chamber of the speaker, resulting in an improved sound.

With the custom-fit insulation materials the acoustics of the speaker is greatly enhanced. Taking the wanted qualities of a communications speaker into consideration - clear intelligibility and suppression of distortions - Phonema uses up to four different materials for an optimal sound design. The important point is the experience of the manufacturer in acoustics - how-to do it right for speakers.

Because of the precise cut of the components to the various speaker boxes, the installation is very easy and can be done within a few minutes. You just have to open the enclosure to fit the parts at the right places. Already exsting extensions like filters and amplifiers can be easily accomodated. The result is a greatly enhanced sound in SSB and telegraphy, which benefits also radio listeners and SWLs.
