Conclusion: I would recommend these speakers for a simple replacment install. Had good sound quality and I haven't even sound deadened the doors yet... Pioneer always has had a good fit and sound for under $100.00!
Conclusion: Needed something to replace my dry-rotted 20 year old speakers in a Subaru Legacy. High-passed at 100hz 12db/o, on about 50 watts. Midrange is superb for a budget coaxial, very clear and detailed. Tweeters are harsh, and get very fatiguing at loud volume. Most of my experiences with Pioneer tweeters are the same, even in their higher end component sets. Off head-unit power they run alright, but when amplified they really come alive, especially on the lower end.
Conclusion: I needed to add some more backseat audio to my 2013 BRZ and these speakers matched the sound performance of the unusually high quality factory speakers provided by Lexus in both appearance and performance. Used a car installer and he complimented me on the choice by saying, "You know these are really good speakers." They perform well. I did have to tighten the grill seating on one to remove vibrations chatter on rough roads.
Summary: Excellent factory replacement speaker, crisp sound, adequate base and treble. I put these speakers in the front doors of my '06 GMC pick-up. Installation was a bit of a challange since the instructions were only generic and not specific to my vehicle, plus I had to make a slight modification for proper fit. If you take your time, it's not rocket science...
Conclusion: Very good high and upper midrange speakers. Clear and efficient. Stays clear at higher volumes. Hard to beat in this price range. Looses depth at lower midrange frequencies and relatively no low end. Not what you buy this speaker for.
