But I’ve also heard little 3/4" doped silk dome tweeters sound every bit as fast. It always amazes me that a little soft piece of silk with rubbery goo on it can sound like a high pitched metal bell when asked to.
I have two JBL horn-loaded compression drivers and a pair of sealed boxes with aluminum tweeters. I haven’t heard soft dome tweeters (yet) but also amazed they can be so effective at reproducing metallic sounds. I'm leaning hard toward the Spendor D7.2s and they are soft dome. Will be buying with a solid return policy just in case ;) Still need to find a place to audition them.
