Before we get started, I should come clean and admit that I’ve always been a fan of Electro-Voice speakers. This goes back to the 1970s, when finding (any) information about speaker design was nearly impossible. Then I discovered that E-V had published a huge library of white papers and DIY enclosure plans. The latter was based on the classic Thiele/Small research by Neville Thiele and Richard Small that offered bass response predictability of various-sized enclosures by applying a few known driver parameters — free-air resonance, impedance, cone area, etc. (As a side note, I — much later — had the honour of inducting Neville Thiele and Richard Small into the TECnology Hall of Fame, which ranks among the highlights in my audio career.)
In my early days, I spent countless hours creating and testing different bass-reflex cabinet designs — all based on the Thiele/Small parameters of E-V components. I was definitely a convert to the company’s SP12C/SP15A woofers and the 12TRXC — a 12” coaxial that essentially placed a T35 horn tweeter in the centre of the SP12C woofer. That particular driver got me hooked on coaxials, although at the time I was also doing live gigs for a local sound company that did most of its bread-and-butter gigs using Altec 604 coaxials in utility cabinets.
