I've got an old pair of BA A-40's that need new drivers. The BA website says new ones would be at least $150-200. My original receipt for the speakers was $145 in 1986. Am I being cheap by thinking $150 plus shipping is a stretch? Can anyone suggest other decent 6.5 inch drivers for the A-40's? I recently replaced two Vifa drivers w/crossovers for my Snell modell J's for just over $200. (Snell btw, was bought by BA).
