I could be wrong about this since I haven't much experience of Santanas, and always in systems that were not chosen by me. At any rate, I didn't think they sounded that good. But it's hard to argue that they are not true Altecs. But citing them as true Altecs seems to me to cut the legs out from under the claim that true Altecs have horns. Altec made quite a few cone tweeter speakers (and with consumer grade woofers and midranges also) long before they got sold to Sparkomatic, and many of them are fun to listen to (more than the Santanas) and, for whatever it's worth, sound more like 'real Altecs' than you might expect, from all the indignation. (This based on having some Capris and having had some of the number named box speakers, and currently using Valencias.) Tastes vary, as do allegiances.
