Because I have no life or because I am obsessed, I reread all the posts and viewed all the picts a second time just to soak it in. It seems that some of the models have gone through some evolution (paper v poly cones (CX's); c/o light bulbs v no light bulbs (also CX's); felt v no felt over drivers (TW and TF)). My TW1's don't have that piece of heavy, thick, stiff felt (?) going across the top third of the woofer as shown in Jamie's pict (maybe that is the 1 to 1a difference). What's with the four-squares of felt giving an open cross in front of the TW3 woofs? I know, I know, to smooth out the frequency response but who would have known to cover drivers and in what orientation to do it? Well, I guess Steve does. And we all know there is felt sandwiched between the two screens covering the woofs on the coax drivers of the CX-17, 27, TW7, SS, and maybe some TF's; but not my TF-2000's which don't have coax drivers. My TF-2000's have felt going across the top half of the top woof and across the bottom half of the bottom woof. The approaches that Steve used totally boggles my mind.
