Words can't describe the quality of build and quality of sound on this speaker. Tight hits and no drone with almost no distortion. I got a Vented, tuned box and powered it with Rockford Fosgate R500X1D and I am serious when I say my review mirror in my 1989 Buick regal fell off the windshield! If you want very high quality sound and a price that won't break the bank, its hard to top this. Let me know if anyone has spec questions, and I hope you enjoy it as much as I do.
