phusis,
I don't know who made the 12" drivers I have. They were part of a system made by an Italian firm named Strumenti Acustici Precisione which put them in a Jensen Onken cabinet. I bought the speakers about 18 years ago, and then later changed out the horn driver for the Western Electric horns. This was easy to do because the horn drivers in the original speaker just sat in a cradle on top of the woofer cabinet. My replacement midrange horn setup actually looks better than the original horns in that system because they have a width identical to that of the woofer cabinet (24").
The woofers in my system barely move at all. I like the sound of such old school woofers with pleated paper surrounds. They may not go very deep but they behave well and deliver clean sound and natural "tone."
The 713b driver is quite old, I believe someone told me it was made around 1939. I think it is one of the best sounding compression drivers made, but, it does have some limitations. First, it does not go quite as low or quite as high as some other Western Electric drivers. Also, it has a 4 ohm impedance which makes it harder to build a suitable crossover when using other drivers of higher impedance. These drivers come up once in a while on eBay and other such sites, but, finding a well matched pair is quite difficult. When a matched pair from a reliable source does come up for sale, the price is quite exorbitant these days.
