I was thinking about going for those cups, however the cup takes the driver in the sleeve, not a liberated driver :| Which means my 125i's would still be in plastic Plus there's a built-in spacer, then the bowls for it... They should advertise them as "If you hate bass, these are the cups for you!" lol
I always think it would be nice to ditch the spacer and make wooden sleeves to slip into the outer cup. Some folks have advised using oven-cleaner to ditch the red as well...but that's a lot of effort just to get a pair of aluminum outer cups..
