Well, the Subaru Kicker upgrade tweeters came in for the front dash and they sound great! With the Kicker tweeter installed on the left side and the stock speakers on the right of the dash I faded left and right a dozen times or so, sampling some Simple Man by Lynyrd Skynyrd, some songs by The Weeknd, and a mix of other Classic Rock and Pop.
Simple Man was the first song and the difference was pronounced. The percussion instruments were almost inaudible through the stock dash speaker, but very tss tut tss tss tut tss tss with the Kicker Tweeter.
Vocals are substantially brighter too. As you can tel from my posts I'm not much of a bright guy.
I prefer the softer highs that are now coming out of the 3/4" silk tweeters in the Sound Ordnance door speakers, but definitely prefer the Kicker tweeters to the muddy stockers.
I was going to complain that the new vocals were too bright and sss sss sssy, but I think the issue is more the signal from the head unit than the tweeters themselves. I'd still have preferred silk tweeters, but that's more theoretical, since I'm a newbie when it comes to audio. These are just my opinions.
Again, for around $210 all in I'm very pleased with the results.
