Can anyone comment on the 'grille bars' placed across the tweeter. Is this just protection from poking fingers? The above picture is the S38II. The first Studio series (S38, S310, S312, etc.) had only one central horizintal bar across the tweet. I have seen other JBL series using EOS where one vertical bar is used. The center bar has a smallish 'cap' which cover the center of the tweeters dome. I thought I had read somewhere at one time that the center cap prevented beaming, but why the extra bars?

Thanks, Mike Brown
