Acoustic Research AR-9 AR- 90 Upper Midrange Dome speakers Original 2000-28-0 Made in USA. This is a pair of the original AR upper mid range drivers designed for top of the line AR-9 and AR-90 floor standing models, both are in great working condition and provide clean response. There is no dent or wrinkle on the dome surfaces. There are some light colored fibers sticking to one dome but have no effect on the sound. AR parts no is 200028-0 and made in US. Knowledgeable audiophiles appreciate that AR dome midrange drivers are the key to and responsible for the well regarded AR sound. Good original replacement AR parts are getting more difficult to come by these days. Both drivers read 3.6 ohms DCR on my meter. I have been a fan of the classical period of AR speakers. In the past I owned AR 4, 2ax, 3a, 9 and 11. This comes from my personal collection of premium quality AR drivers parts. I know how to protect and package the delicate speaker drivers.
