Last year I inherited a pair of L65 Jubals. The woofers have a reflective purple tint to them. The back of the cones have a fiberglass textured spray with "126 A" written in white marker, implying that it isn't the typical replacement 128H re-cone kit that fits the Jubal L65, L65A, and L65B woofers. Are these the original cones that came with the speaker in 1975? Does the reflective purple tint on the front mean these have been re-coned? Are these the original cones, but they sprayed some purple coating on the front to "preserve" it or something?! I can’t figure it out!
