My one-off Tannoy HPD (12" Dual Concentric drivers, ca 1975, custom built crossovers and enclosures), are my forever speakers. They cost in the $5K range to build, with very high quality parts, but I firmly believe I couldn't afford this quality of sound if I were to buy new. I do love them, and will die with them, and hand them down to my children.
