The PHD is our main invention and technology at phonon.

The starting point of our idea behind phonon is to accurately deliver the musician's true sound.

Through the phd device, the original soundwave is not effected or altered. As a result, it delivers "a never experienced before" honest reproduction of the original sound.

How does it work?

The PHD is a small, very sensitive vibrating metal device that connects to the + and - of your speakers (for pre-amplified speakers, you will have to open your speakers to connect it).

The PHD vibrates in harmony with soundwaves coming from your speakers, simultaneously transmitting ultrasound waves that compensate for the delay in transmission of some frequencies, causing all the frequencies to align. The original musical waveforms are replicated without changing the characteristics of the speakers.

The PHD enhances your perception and sense of hearing, making you feel and experience the "real sound" of the original waveform. Result: a more precise and detailed soundscope.

The PHD concept comes from the unique notion of compensating for the waveforms that speakers cannot replicate.
