PHITS Y-10A for Yaesu SP-10
Phits is a set of acoustic foams designed to get a much
clearer sound from your speaker.
The sound produced by the speaker reverberates
backwards inside the cabinet and adds noise to your
transceiver signal. Signals, as consequence, lose
intelligibility. This noise usually occurs bellow 1000 Hz.
Phits reduces reverberation to a minimum level by
absorbing sound and by invreasing the speaker mass.
