ar_pro Posted March 12, 2012 Report Share Posted March 12, 2012 200027 was original to the AR-90 and AR-9 - not sure where the 200037 was used.Does your 200037 have a paper or poly cone? Link to comment Share on other sites More sharing options...

michiganpat Posted March 13, 2012 Report Share Posted March 13, 2012 200037 is the part number for the 8" woofer used in the AR18S and AR28S Link to comment Share on other sites More sharing options...
ar_pro Posted March 13, 2012 Report Share Posted March 13, 2012 Interesting.I wonder how that woofer found its way into the AR-90s?In the early 1990s, Acoustic Research was supplying a "factory replacement" lower midrange that had a paper cone, but with a much smaller dustcap than on the original 200027 driver.In more recent times, AB Tech used an 8" poly-coned replacement.I've heard both of these replacement drivers in the AR-9, and neither one sounds right.

michiganpat Posted March 14, 2012 Report Share Posted March 14, 2012 ebay is your best bet, maybe audiokarma's bartertown.. 200027 is the LMR on the 9,90, and 94 Link to comment Share on other sites More sharing options...

Roberto Posted February 13, 2014 Report Share Posted February 13, 2014 HiI'm Roberto, from Italy,I decided to start write only now as I was out of my homeland for workI will continue this topic because the discussion is the same..3 years ago I saved two ar90 from the garbage, unfortunately the condition are very bad...the cabinet need to be repainted, the two woofer and mid-woofer are lost in both speaker, and one midrange have the cone and surrounding cut in 4 parts...While some midrange are available on ebay, more difficult is the situation for the woofers and mid-woofers..I read some topics on the forum but I understood that even the abtech replacement are not the proper one... My technical knowledge is not enough for take the right decision..what you suggest me to do? I have to wait and found it on ebay? or what?Any help will be appreciated , Thanks.
