Oh dear, I'm going to disrupt another thread.

I was talking to Laurie Fincham of KEF a rather long time ago, (um - 30 years or so) and I asked what the thinking was behind the B139 - since it was the iconic low frequency driver of its day.

"Purchase Tax"; "er, pardon?"; "Yes - purchase tax applied to speakers which were round or elliptical. So we took a circular speaker, cut it in two and put two straight sections in. Since this was neither circular or elliptical it evaded Purchase Tax"
