FWIW, IF you still want a bit more bass, you could try: 1. Seal the ear side baffle ports 2. Punch a few holes in the stiff felt over the back of the driver grid 3. Enlarge your 3 mm modified bass port to 5-6 mm, or 4. Remove your modified bass port and leave the cup vents stock with their black felt in place on the inside.
