I have a few suggestions for you I suppose. If you want wood cases and good vintage sound with a warmth to it, look to the 60's. I have a pair of Jensen TF3 that would be perfect for you if you wanted them (or look online, idk) - only about 20 inches tall, thick solid walnut cabinets, famous 10'' woofers, good sound with the warm signature you're looking for. Make sure you get ones with the original woofers though - the woofers are worth more than the rest of the speaker combined since they were also used in fender amps, so it's common for people to part out the original woofer and replace it with a cheaper one.
Still looking for small, try Pioneer HPM 40's. Those guys are fairly small and underrated - not to mention super common/cheap to buy online and easy to find parts on if you ever blow something up. They are veneered particle board (fairly standard) with a walnut look. Only about 18'' tall, fairly light, but still kick like a mule when you turn them up. I have about quadrupled their rated power without popping anything on those (funny story actually, the volume caused a good chunk of my friend's ceiling to fall, haha). Those guys sound on the warm side too.
Final suggestion, look at JBL L26 decade series speakers. They are a little larger, but still quite underrated and underpriced, but usually slightly more expensive than the Pioneers. They are also veneered particle board. They have the stereotypical warm signature you might be looking for with a high-end aesthetic.
Otherwise, many other things built in the 60's will probably have the cabinet quality/type, size, and sound you want.
