Overall good. Smells glue a little bit, but hope it will vapourise. Obviously it's not as powerful and bassy as the ones with bass reflex fitted,but for the rock and metal music this one is a better choice, as the speaker has faster response for a bass, as is sealed, does not have port(bass reflex). Box is really compact, so you can't really expect super low meaty bass. As it's compact and no bass reflex, bass doesn't go far low, not as low, as the one with bass reflex, but enough. It's 91db,so it's not super loud in a saloon car. In hatchback it's loud enough. I had a JBL 1224 Slip stream, very powerful, going far low, like 25hz, the 1200b going only to 33hz around. But the box is very big.
