  1. Try adding 0.01uF or 0.10uF Film and Foil bypass capacitors across the Mundorf E-Caps. These are cheap...on the order of a buck apiece. The shipping will cost more than the caps, so I suggest you by a few of each to see which ones you like. These will get that last ounce of grit out of the midrange. https://www.parts-express.com/dayton-audio-dffc-001-001uf-400v-by-pass-capacitor--027-450 https://www.parts-express.com/dayton-audio-dffc-010-010uf-400v-by-pass-capacitor--027-452 Also, try adjusting the attenuation switches to -3dB on the tweeter and -6dB on the UMR. Keep the LMR switch at 0dB. Let us know how it goes.
  2. Yes, they are dinky compared to those on the 12" woofers in the AR9. But they do seem to get the job done anyway.
  3. Nice! Glad that you like the sound. What kind of sources have you been using? Any manipulation of the attenuation switches, or are you listening to them "flat"? And you know that I've been waiting since January 2017 for you to do this recap. LOL
  4. Maybe we can have a CSP convention at @frankmarsi house to hear his double stacked LST's. People probably would not want to leave and it would be like Woodstock with traffic jams up and down the street. LOL (Just joking Frank.)
  5. I agree with ar_pro. Do the work in situ. Look at all the "stuff" I was able to put into an AR915 (UK version of the AR91) without removing the board. (I had a bunch of surplus 24uF Solen poly caps, so I cobbled four of them together to make a replacement for the 100uF NPE. Totally unnecessary as opposed to installing a new 100uF NPE, but as some on this forum are aware, I had a serious vendetta against those Solen polys.)
  6. I've always wondered about the need for these spikes. My AR9's stand on a carpet with thick foam base on a concrete floor. With my installation, I wonder how these spikes could possibly help because they aren't "coupled" to a wooden floor as they would if in the living room. Right? (That's one of the few advantages to having one's system banished to the basement.) Also, regarding the foam around the tweeter, I installed some aftermarket felt from vintage-ar: https://www.ebay.com/itm/ACOUSTIC-RESEARCH-SPEAKER-AR-9-AR90-AR91-AR92-AR11-AR-10PI-TWEETER-RINGS/192715894526?hash=item2cdec32efe:g:vnEAAOxyhodRzaLC:sc:USPSFirstClass!07869!US!-1 Did it make a difference? Perhaps, but if so it was subtle. I never tried installing anything around the UMR. As I noted in another post, I'm extremely happy with my AR9's right now and hesitant to fool with them any further.
  7. I'm very happy with my AR9's since they've been recapped (Poly caps except the UMR which are Mundorf E-Caps + F&F bypass caps across all caps) and I went to fancy cables that were gifted to me. But the thing that made the greatest improvement was moving the speakers away from the walls and toeing them in a bit towards the sweet spot. That works for me in my room and listening location but it may not work for others. Since the "digital age" I have never liked the AR9 or 90 with the UMR controls set at 0 dB. I prefer -3dB on the 9s and -6dB on the 90s. Even with the UMR attenuated, I still use a bit of EQ when playing classical music through these speakers. Regarding the AR5's for classical music, I had a pair of them as well as AR3a's. My preference for classical music was always these classic AR speakers, but they are bit reticent for my taste when it comes to jazz/pop/rock. I've never heard the AR LST, and I speculate that it excels with all genres because of the multiple tweeters/midranges.
  8. xpat, I admire your set of balls bringing up this topic on this forum. Question: When you upgraded to the Type 4, did you first try the speakers in the same location or did you move them further into the room/away from the walls etc? Sometimes just moving the speakers a bit can make a noticeable difference.
  9. Here are some pics of the AR binding posts vs. the Parts Express offering as noted by DavidR. The AR binding post will handle a banana plug, but it cannot be inserted all the way. That may or may not bother some people. Both the AR and the Parts Express binding posts have a hole to insert a wire through it. The wire shown attached to the AR post is 16 gauge. That's the maximum gauge this binding post will handle, albeit with difficulty "threading the needle." The Parts Express binding post has a larger hole. The wire in the picture is 12 gauge. It will handle an even larger gauge if that is one's druthers. Have fun!
  10. Regarding the binding posts, I always find the OEM posts on the 9 series to be a bit of a nuisance with either bare wire or banana plugs. With bare wire of reasonable gauge, I find that the nuts on the original binding posts are a bit narrow for adequate tightening of the wire...even with pliers. And as DavidR said, I found that banana plugs only go half way in. If you want to keep the original binding posts, may I suggest attaching spade lugs to the wire? It is much easier to tighten them down to the posts. I prefer the Parts Express binding posts because they accept standard banana plugs properly. And I can simply remove the plugs when I want to move the speakers for cleaning. Your speakers, so you do whatever you want. (Finally, as @Giorgio AR says, production of the Parts Express binding posts is probably Chinese...but you should be OK as long as you don't eat them.)
  11. There are so many variables with speaker placement. I have probably made the most egregious of sins by pulling my AR9's away from all the walls and toeing them in. I prefer them positioned like this in my particular listening environment. The imaging, breath and depth of sound stage is tremendous and I have no complaints about the bass response. In a nutshell, just experiment to find the best sounding placement to your ears...and whatever won't get you thrown out of the house.
  12. Although my handle is "AR Surround," I'm afraid I can't help you David. 😉 Did you try vintage-ar? I know that the surrounds Larry supplies are the correct roll and compliance.
  13. A question for you Harry...Do you ever find the lack of attenuation switches (0dB, -3dB, -6dB for Tweeter, UMR and LMR) on the AR9LSi problematic? I ask because I've dragged my AR9's around for the last 41 years and have found that I've preferred different attenuation switch settings at each location. I guess that since I've used AR5's, AR3a's, AR9's and AR90's, I find the inability to make adjustments a bit unnerving.
  14. I wouldn't put it ON the glue, just close enough to get some softening. This will drive you crazy, David, but what I did was simply pry the things off with an chiseling blade in an X-acto knife. If it took off a tad of the board with it, then so be it.
  15. Or perhaps using a soldering gun...i.e. Weller 140 W...and prying up the caps a little bit at at time.
