It appears to be a mid-bass component speaker.
it is.
The pic in the link you posted blackdiamond shows the seperate tweeter that is included in the package as I somewhat suspected.
Those look like pretty decent speakers. They're a bit pricey for what they are so I might shop around to see how much the price may vary from one place to another. Don't exclude checking with local audio dealers since you never know what sorta deals they may be willing to make.
I'm usually partial to a brick and mortar establishment myself since you can see the items in hand and get a better idea of what might be involved when it comes to fit and installation. Maybe that's just me.
