Horn speakers for vintage sound

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. 

You will get vintage sound from horn speakers all right.  Useful for bass, correct exponentially derived horns are hard to get neutral.  The purpose as you know is to minimize diaphragm excursion so it stays in the linear range. On the flop side they are efficient, but not as good as quarter wave.  In the end, I find the sound fatiguing but you may like it.
