Has anyone else tried any mods besides pad mods? (I stuffed the bottom of my pads with foam weatherstripping, because I wasn't getting a good seal. After doing so, there's bass!
I think (can't be sure, as I don't have an unfilled pair to do a direct A/B comparison) I tamed the treble splashiness a bit by adding Bonded Logic Ultratouch insulation to the subchamber behind the driver's polepiece vent. I also lightly filled the outside chamber, but I'm not sure that did anything.
