I have finished making my first pair with ED29689 but the the right side is much quieter than the left side from 20-1khz, is it possible that I have overheated the driver? The seal is perfect so it is definitely not the seal.
My (unrealistic) goal is anything between these 2 curves. Also is there any differences between soldering the cap directly on the driver like the proprietary drivers and connecting them by wires like your design? EDIT: I tried the TWFK without caps and they sound pretty decent, how does adding caps improve the sound?
Do I need the capacitors if I am only using the TWFK? I think a capacitor is used to connect the positive terminals on the proprietary TWFK that are used in the ue700 and dba02 but what does it do to the sound?
