I've had my modded t50rp with custom cut the aluminium cup for more than a year now, but just had it covered in leather, dampened with dynamat extreme and added lcd-2 pads recently. It's quite pleasing to look at
with the original fostex
You can see on the side there are vents for bass. There are 4 vents per cup because I want to test with different pads also
All I can say is ... sexy. How much for everything did it take to make those beasts.
