Actually did a bit more testing on the X00, I think the stock foam position is the best, possibly it is different on the 900, but every other position makes the bass worse quality.

The lawton driver mod definitely helps, the pad mod seems to improve the sound a bit, cannot undo it now to test but seems probably better. Will do the tape mod on the cups tomorrow hopefully that will smooth the treble a bit.

I did the Lawton driver-only mod to my X00 Purplehearts, and also added ZMF Ori pads. That's as far as I got with mods, but consider both to be very worthwhile.

I always intended to also try rotating the foam disc, as well as @Vracer111 's custom attenuator mod, but never got around to the @ 10 minutes required to do both LOL! Yes, I'm lazy :p

I currently have tr-x00 mohangy with Lawton mod on the drivers only. I switched the mohangy cups with th-900 cups, I wonder how they tape mod will effect the sound. I will try tonight.

I have the TH600s. I did dynamat on the cups (because they're metal and super resonant) & used tesa tape instead of medical tape, worked wonders.

Concerning the foam ring adjustment mod.. I've seen some people say there's no difference.. but I definitely notice it. It's slight. I think I like "3/ #2" the best.

*****Do Not Trim Your Lawton Pads*****!!!
@Whitigir I was wondering why we shouldn't trim the Lawton Pads. They pretty much obscure the hole behind the clips. Also, the THX00's achieve deep bass by limiting the amount of driver available and their rings don't have breathing spaces (at least the ones on my TRX00 Ebony's don't. Is there an advantage to opening up more to achieve bass versus closing off part of the driver?
