Sooo....Bill-p, when are you selling your modded HD 600?
Did you send it UPS, USPS etc etc? No word yet.
That's funny...when I EQ'd mine by ear, I put -3 dB Q4 at 3500 Hz and -4 dB Q4 at 5500 Hz. I also have 3 dB Q2 at 7500 Hz for some reason.
Yeah... I'm honestly not sure what the differences are between my rig and others that cause the other rigs to not show the amazingly fast speed of these drivers, but I think they are quite fast and clean, and that contributes to their resolution and detail retrieval capability.If not for the weird ridge around 3-5KHz, these would be practically perfect IMO.
