i used to have 302A Urbans and miss them very much. they were too big for our new place though.
anyway, mine had the following work done to them. i went from the stock 2uf cap/25ohm resistor for the tweeter network to a 2.5uf/20ohm combination. this lowered the x-over point for the tweeter and increased it's gain just a touch. about a 1.5-2 db difference.
next up, i used spacers to tilt the tweeters more up to ear level. this helped greatly and tilting the whole speaker back puts the mids off axis.
lastly, listen with the grills off, less high frequency smearing from the grills.
as far as the tweeters, they naturally roll off around 13kHz. you can NOT fix that. it's by their design. i tried some swan TN28 top mount tweeters and disconnected the 200y bozak tweeters. the speakers sounded very modern and lost a lot of that bozak lushness.
thing is that the stock tweeters also act as upper midrange drivers and they sound great for this purpose. if you want some more "sparkle" try the swan TN28 with the appropriate x-over to use as a super tweeter.
anway, buy replacement 200y tweeters on ebay. there's always lots to choose from.
