    Rated 4 out of 5 by from Perfect sound Bought these to be stealthy leaving my neighborhood in the morning but still be as obnoxious as need be for hostile takeovers on the street. Wish they would have payed more attention to packing for shipping though. Nothing a little controlled hammer work on the flanges couldn't easily fix. Good stuff, fast arriving, no real complaints otherwise.
