Powered by the cutting-edging miniature electrostatic tweeter technology, It employs a six micro gram, gold plated membrane held against a plate charged up to 400 volts. The electrical signal voltage is amplified up to 100 times via a built-in miniature transformer. The electrostatic attraction and repulsion effects induced by music signal triggers the membrane to produce acoustic pressure. Simply plug into your player and high fidelity music is ready to go.
What is POLA
‘‘A design that truly brings out the ES driver’s qualities’’
The first thing that comes to our mind when the latest Sonion ES-driver consisting of fancy micro step-up transformers are sent to us in early 2018?
It is not about achieving higher specs, but rather what we can do to utilize the design for a higher level of perceived enjoyment and a more immersive experience in listening!
POLA - the end result after a year worth of product research, houses a large and fast 13MM Graphene (carbon allotrope) dynamic driver driving a lot of air, implemented to pair with the latest ES driver quite alike traditional speakers with a super tweeter.
Now you can hear very deep and layered bass, charming and full-bodied vocal and even fine details in the ambiance thanks to the new tweeter innovation and synergy of the design.
The original POLA is displayed at Canjams in Early 2018, earliest prototype is a 3D metal printed universal housing featuring a smaller diameter dynamic driver with the electrostatic drivers. The sound is very well received however together with AAW we hope to push the design to its limits. During 2018 we have tried to put prototypes with BA, multi hybrid designs at show and private gatherings for feedbacks, and in the end we are answering with the current design that houses not only specifications that goes up the roof, but concrete driver implementations allowing the design to scale up with sources and reflects the mastering’s quality. At just 16ohms POLA will work with most phones and laptops, and quality DAPs or Amplifiers supplying better power, also well mastered tracks will definitely boost performance to a more enjoyable tier!
