Conclusion: Don't really know how to review these because I don't know how to compare them. I first listened to them in a local audio store and they sounded very clear. When I hooked them up in my car to a rockford Fosgate p300x2 they still sounded good but i think they could use more power.
Conclusion: Purchased to replace 9 year old Infinity's. Are hooked to same Alpine PDX-F4 amp. What a difference. They play louder and a bit cleaner. Highs are not quit as crisp as a hard doom tweeter but do not have the occasional ring as a hard doom. Is a fair trade off. Sonic's price is definitely a plus.
