Those "plastic dome tweeters" were cheap to add in the speaker enclosure. Criterion 2002+ are great speakers. I still have a pair here that gets active use. Also have two 2001's but both woofers crumbled years ago and I replaced them with a pair of Dayton woofers. They're in my basement man cave. Also have a pair of Criterion 150's which mimic AR-3's quite well.
Also have a pair of Criterion 3X's that still sound great. These speakers followed me for three summers down the Jersey shore living with several guys in a summer house. Beer didn't seem to bother these speakers

but they do smell a little funny.
Had a few other Criterion speakers over the years, but for one or more reasons, found them new homes.
