Pressure-balanced Acoustic System
The PBAS is a step from a similar system previously implemented in the DAUNTLESS In-Ear Monitors. It features an intricate network of acoustic pathways that is integrated into the 3D-printed shell structure and the utilisation of a balancer tube for pressure control. ZEPHYR takes full advantage of the PBAS system to significantly enhance the overall sound qualities of the drivers.
Acoustic Balancer Tube
The Balancer tube is a key component within the PBAS, acting to balance the pressure between the front and aft sections of the driver. Its critical dimensions are shaped using a laser cutting process to precisely control the tolerances to under 30 microns (about ⅕ the width of a human hair). This level of precision is required to produce inter-chamber pressure relief with a specific rate of pressure change between the front and aft sections, allowing the dynamic driver’s response to be fine-tuned in order to achieve our desired sound signature.
Titanium-coated Membrane Dynamic Driver
ZEPHYR’s specially engineered Dynamic Driver (DD) takes advantage of Titanium’s excellent mechanical properties, featuring a lightweight Titanium-coated membrane created through a vapour deposition process. The thin layer of Titanium improves the stiffness of the membrane while keeping the membrane inertia low, resulting in a superior transient response and detail retrieval. The sound produced is quick, clean and with a firm bass.
