  1. Hi AR-Pro I think AR must have had the same thought. You will probably remember that while Ken worked at AR he produced the AR 338, it had an 8" woofer and similar looking units to those you mention for the mid and Tweeter but different. Perhaps that woofer would be a good prospect for the project, if you can obtain two from the remnants of AB Tech demise. The cabinet dimensions and type/quantity of fill are already specified The crossover for the 338 might also be a good starting point. The following is from the CSP archives and provides a review of the unit. http://www.classicspeakerpages.net/library/acoustic_research/ar_303_series/ar_303_series_other/ar_302_and_338_review_by_da.pdf I like the 338.

  2. This may be of interest, a spec sheet for their large cap series,63V. I have no idea the quantities of those listed available on the sheet. 1716.pdf 1717.pdf
  3. >Was there something wrong with the photos? No, same pictures as below. The link may have been "lost" when the query was shifted from the "News" to "AR" Forum.
  4. Unfortunately, no. I wish I had more AR speakers to document and listen too.
  5. Here's another upload of the PDFs and pictures. 1210.pdf

From my AR6 (European version) I read the Resistor//Capacitor combination to be 10//24uF. INDUSTRIAL Royalite long life 24 uF 50V NP. The inductor is #4 (0.88mH). I'm currently using the "Blue" capacitor and the sound is good. I will experiment with a polyPro (NorthCreek)as the crossover is around 2,000 Hz. I used a 10 Ohm North resistor from North Creek and a cheap 24uF cap until I can replace it. My resistors were damaged due to overheating, I had scorch marks on the fill! I expect to change the 24uF to polyPro (NorthCreek) when I can. The pdf shows two crossover circuits which I believe are correctly transcribed from pictures, but no guarantees, ok. Hope this helps.
  7. Oops, sorry, should have read the speaker number properly.
  8. The following is a quote from Tom Tyson. "I think only the AR-14, AR-16 and AR-28 used that 1-inch tweeter. The use of the 1-inch vs. 3/4-inch tweeter was dictated by the configuration. For example, the 3/4-inch tweeter has better dispersion than the 1-inch unit, but cannot go as far down in frequency, such as needed in a 2-way speaker. The 3/4-inch domes were almost always used in 3-way systems with crossovers up around 5KHz. The part number (not serial number) on 1-inch tweeter for a AR-14, is Part# 200024-1. --Tom" I believe the modern "classic" AR models from 1992 also used a 1" soft dome tweeter with the similar face plate ( a bit smaller, with the diagonal distance between the scew holes of 3-3/8" rather than the 4" on the original). A part number number for the 1992 version is 1210148-0 (922TND).
  9. I picked up a pair of Warfdale XP2 speakers. I find them nice to listen to (No real bass of course). Does anyone have any comments on their back ground? Thanks
  10. Rich, Thanks for the reply and information. I look forward to your further comments. Richard
