DUNU Vulkan Hybrid IEM

DUNU has announced its latest hybrid IEM which is for sale as of today. The DUNU Vulcan will be sold for 380$. With the new Vulkan, DUNU is also celebrating the 10th year of its hybrid IEM engineering period. The first was DN-1000 which was launched in late 2012.

8 mm Structural Foam Cell Dome

One of them is an 8 mm Structural Foam Cell Dome with Soft Independent Surround dynamic driver which is inspired by DUNU’s flagship Eclipse advanced driver designs, this unique 8 mm woofer driver pairs an extremely lightweight yet rigid structural foam cell dome to a flexible, independent surround, allowing the driver to behave like a natural woofer, with deep bass reproduction and dynamics.

8 mm Nanocrystalline Titanium-Coated Diaphragm

The second one is an 8 mm Nanocrystalline Titanium-Coated Diaphragm dynamic driver which is positioned behind and acoustically coupled to the foam cell driver, this titanium-coated driver does not have a domed design and allows the dual unit to reproduce lower midrange frequencies with stellar linearity and quality transient response.

These two 8mm dynamic drivers are used in a coaxial design, in one shell to be precise. Besides the dynamic drivers, the DUNU Vulcan has two Knowles BA drivers for mid-high and one Knowles Dual-super tweeter BA driver for treble in an entirely new acoustic setup.
