The King of Midrange: plus, compact cabinet size & perfect for SETs!

The Western Electric / Altec 755 series full range drivers. As far as midrange drivers go, this is ROYALTY. As in the fairy tales, there's always a catch. 755A - best of the lot, quite possibly the best ever midrange driver. Sadly, unobtanium (hyper-rare & silly expensive - 6K$ a pair nowdays - when you find it) 755B-E (later series, "not A") - reportedly not that magical midrange, but will work in small cabinet. (Well, just how well? I have a pair of 755C, will build a cab - probably next year & we will all find out! Until then, peel your eyes open and if you find a deal for one of these then get them!) Unfortunately the B-E series have also become super expensive (though under 1K$ a pair), so it's not a bargain project no matter which driver you choose. As the letter progresses, the midrange quality lowers. Plus, later models are ferrite, not Alnico. Earlier the letter, the better the midrange...

Esmilla is a professional violinist (and an expert amplifier and speaker-builder), so we all can take his recommendation for midrange! ;)
