Dan ... I do not have the waterfall graphs to prove it, but by ear I am sure that the decay times have really evened out. The sudden "lock" into realistic sounding is what has me so jazzed about these tube traps. I think the first order harmonics of the bass notes were muddying up the mid-range, which is why 11's are working when theory says 24's. The subs are not on for music, which is another reason I am getting away with the 11's. Getting 24's would be wretched excess ... like that has ever stopped me.
