Horn speakers for vintage sound

If you would like a slightly upgraded version of the classic American horn/big woofer concept, and you are DIY-savvy, Pi Speakers might fill the bill.

5k goes a long way with Pi Speakers.

Also, USAM has a nice used Volti Razz going for under 4k, and a nice-looking CornScala for under 2k.  

Finally, there are several used Altec Model 19s available for 5 grand or less that should fill the bill.  

I have not heard any Shinjitsu Audio speakers myself, but, I find their design fascinating and the price is reasonable.  Their speakers utilize a horn midrange/top end and a back-loaded quarter wave woofer of small diameter.

Cornwalls and you're done, 4-5k used and they're great.
