Giorgio AR Posted October 13, 2019 Report Share Posted October 13, 2019 A friend of mine has two AR92 pairs, who have been in the cellar for about 5 years. A couple has non-original woofers, the second pair, the protagonist here, has woofers with crumbled foam and a dent on a midrange dome. We started with external cleaning, the cabinets then received a light coat of linseed oil. The 200033 original woofers with a round magnet (detected resistance of 3.5 and 3.6 ohms) were disassembled and taken to my house for refoaming, at the time I put in their place a pair of my 200040 woofers with square magnet, visible in the last photo (resistance detected of 6.4 and 6.4 ohms, aesthetically they are the most similar to the original, foam glued under the cone). I fixed the dent of the midrange, no changes were made to the crossover. Connected to a Technics SU-V7 amplifier they have shown a splendid sound, no imbalance between low frequency and the rest of the range: mid switches. and tw. on the back set to -6db both. A wonderful pair of AR92s.
