some sweeps revealed to me that the vicious peaks in my t50rp are at 1kHz. Any specific materials I can try to cure this? It's literally piercing loud at 1k, at least twice as loud as everything else that seem fairly balanced. I have paxmate in the bottom layer of each cup, flush-loaded the baffle with clay, stiff felt with a electrical tape reflex dot underneath on each driver and 80% closed bass port (no felt). earside felt cut away and paxmate donut under some shure pads with lifters. The original stock white filter is gone. My guess is I should try those pop-up sponges mentioned some pages ago if i can find some.
Take 6 regular sized cotton balls, tease them apart, stuff them in the cups (6 per cup). That should solve your problem.
I would also suggest removing the stiff felt from the back of the driver and just leaving the reflex dot. It sounded pretty nice that way with the cotton in the cups. I also did not like what the risers did to the sound with the 840 pads.
