What is the recommended enclosure size for sealed and ported enclosures for each speaker?

You can look up the speaker specs on MB Quart’s site, but there is no recommended enclosure. These are designed to be infinite baffle or free air applications. (In your door or rear deck.) Any reasonable sized enclosure will work though.

Are these 3-way or 2-way ? The box i received says 2 way. But there's a sticker saying 3-way?

Ones I got are 2way. Woofer with tweeter in center.
