Summary: Replacement for the stock dash tweeters in my 2015 impreza premium. This car did not have a "premium sound" upgrade. These tweeters have very good clarity and do not overpower the stock door speakers. Not too harsh or bright. I had to move the treble down a few notches from flat.
Pros: Lower cost, great clarity and responsiveness
Summary: A fine tweeter at a fair price. I replaced the stock tweeters in my 2014 Subaru Forester and greatly improved the clarity and depth of female voices and jazz instrumentals. This is my third vehicle in which I used Infinity Reference speakers, and I've been pleased by all.
Pros: Value, quality, variety of mounting options, sound great with OEM head unit (7-8 watts?)
Cons: None, but some facility with tools is helpful.
Summary: I received my speakers and tweeters within two day. Box came in great shape. I drive a 09 Honda civic. It took about 30 mins to install all speakers. Turned them on and realized that I had made the right choice on speakers. The bass sounds amazing and is still clear as can be.
