How do you define a vintage looking speaker? How much of a kit are you willing to do for yourself? Some come with a knocked down box, or perhaps just the baffle, and assembled crossovers, some have you do pretty much everything including building the box by just providing a design and BOM. You might look around at various kits in your price range at diysoundgroup.com, madisoundspeakerstore.com, meniscusaudio.com and maybe parts-express.com.
