How does the EDL K3003 kit sound?

Equipped with the Flagship 8mm Micro-Tesla and XWB driver

This is a 8mm driver powered by Mirco-Tesla driving technology with Ultra Wide Bandwidth (5~46 Khz) performance. It’s our flagship product originally used in our IE800 kit. We custom a special high impedance (40Ohm) version with low bass boosted 5dB to better complement the low-band of TWFK-30017. We proudly and highly recommend it if you are looking for the extreme experience.  Compared with the AKG 9.2mm driver, this Tesla driver has higher resolution and better airiness (+3dB at 8-9 Khz), and it has unparalleled punchy bass.

See below for the measurements using IEC711 coupler, ARTA and customized sound card.

Step 2: Install the dynamic drivers

The edges of the housing perfectly match the shape of the 9.2mm dynamic driver. Glue the driver to the housing, wait >12h until the glue full dry and air tight. Connect the 2 wires from BA driver with the DD driver. Note DD is also with polarities and green cable in the pic is connected to the + pin.  If you have a IEC711 coupler, this is a good time to measure the frequency response and ensure channel balance.

Step 3: Install the back cover and cable

The AKG K3003 back cover contains 3 tiny component: the stainless steel shell with AKG logo, the inner bracket and a black plastic cable pipe. Assembling them with the cable is very tricky to even experienced DIYers. We pre-install them together as shown in the pic, to save your time and risk.
