  1. I acquired these with a lot of 16 speakers. Finally got around to them. One woofer metered ok but was very noisy. Turned out to be a cracked spider. Repaired that, re-foamed the drivers, and lit them up. Oh my! Was not expecting to be impressed, but these are fantastic speakers! I cleaned up the cabinets, and other than a bad water stain on top of one they are starting to look respectable! Recovered the grills and have been enjoying them for a week or so. Wondering if anyone is familiar with these. There are 3 caps and I can read the values on two of them but the third was glue
  2. These have been sitting around for a while because they needed midrange pots. Finally got around to ordering 10 ohm pots. Just gotta modify the shafts so it will accept the original knobs. 3m Mincom A2000. Can find hardly any info was told by one gentleman that these were never mass produced and only included with a Mincom studio as near field monitors. Not sure if that's true or not but they are certainly well built and unique drivers for sure. He also said that everything including drivers were made by 3m. Mincom had the contract for NASA back in the day during the cold war, so no
  3. I asked indeed. I suspected that the 9LSI was better, but that’s what I have. Truly wanted opinions. I like my LSI better than the LS but cannot comment on the 9s because I’ve never heard them. Thank you for your opinion...
  4. I’ll have to see if I’ve still got my list for the value of the caps.. I did find this pic on my phone... hmmmmm, photo does not want to load.
  5. Got these on trade a while ago. Until that point I had never heard of Design Acoustics and they intrigued me. The seemingly haphazard placement of the mids and tweeters (all Peerless) contradicted the heavy, well built and beautifully finished cabinets. The two 10” rear firing woofers should produced good bottom end... All 9 drivers appeared to be working, and while they had potential, they weren’t great compared to my AR9LSIs or my Heathkit AS1348s. I decided to open them up for a look see. I desoldered a few of the caps and they metered way out. I re-capped them and they so
  6. Hey Luigi. In my comparison the same amp/pre source was used for both speakers. (Nikko Alpha I, Beta II, Sansui SR838). The LS had been re-capped two years ago, the LSI were original. All drivers in all speakers metered well and functioned perfectly. They were placed beside each other for the test but I did not swap positions.
  7. Just curious... I recently had the opportunity to A/B my set or AR9LSi speakers with a set of AR9LS speakers. I’m wondering if others have had a chance to hear these three titans of the AR lineup. I read a lot on the original 9s, but not much on their successors. Listening to the LS vs the LSI, I preferred the LSI. The sound, to my ears, was more refined, better detail. Vocals were clearer, strings and sax better. I have never heard a set of the original 9s. I wonder how they would compare...
  8. Mine was also too soft to get any useable info from. I got my foam cut at a local foam shop. For $60 I got 3 different weights. They are a tight fit so I didn’t glue them in. I’ve been testing the 3 different density sets and I can hear no noticeable difference.

    Ar10pi

    I agreed to trade a friend the first set of AR10pi that I got a few months ago. I agreed to the trade before I was done. After I finished and tested them I instantly regretted agreeing to the trade. I found another set in a city close by and bought them based on two fuzzy pictures. They were in worse condition than I expected, but they turned out pretty good. Sound as good as the last set, so I’m happy!!
  10. All done, caps removed metered within 25% and ESR was low, but I am sure they sound much better now. Could just be me though...
  11. Once this is done, I'm on to a set of AR2AX with mismatched woofers and then another set of 10pi's.
  12. Thanks for the info Brian. Would have been a time saver for sure. I already have mine all apart, new caps in place and I'm ready to test to make sure I didn't make any mistakes. Then I'll mount in the cabinets and see if there is any improvement. Not expecting much as all caps metered within 10% but it needed to be done eventually. Once everything is in place and working I'll renew the ferrofluid in the tweeters and mids and everything will be done. I have already re-foamed all drivers and replaced the foam is the bass chambers. Cabs and grills are mint so no need to refinish.
  13. What a terrible way to mount a crossover!! The LSI uses a circuit board with the resistors on the top side, the inductors around the edges mounted on a melamine board and the capacitors on the bottom side of the circuit board. The binding posts come through the melamine board and are held in place by a nut, the post continues up into the circuit board and is soldered into the circuit board. The caps are glued to the melamine board. Problematic for re-capping. I broke all 4 binding posts because the solder had wicked down the threads. Heavy use of a heat gun and putty knife all
  14. thank you all for the information. After prolonged listening, I have come to the realization that these are the finest sounding “bookshelf” speakers I have ever heard. I am blown away with the full sound from these smaller cabinets. Friends assume I am playing my 9LSI speakers and are surprised when they realize it is the 10’s!!
