I have a pair of the Little Baron's. The number is 345, and they are two way speakers, 10" woofer, 1" silk dome tweeter, one of the pair has a front port. The big brother was the Baron, or 355. It was a three way speaker, and one speaker was ported. There was also a Model 335, known as The Baroness. I think it had an 8" woofer and 1" silk dome tweeter.
I have attached a review of the 355.
