  1. Just an update after all these years, I just ordered a batch of the fabic that RoyC called out in this original post, and I always appreciate his, and JKent's thoughts and advice on rebuilding Acoustic Research speakers. I've done a pair of AR-4ax and my "daily drivers" the mighty AR-3a. Thanks everyone!
  2. I'm currently running a pair of Antique Sound Labs, Wave AV-25 DT http://www.divertech.com/aslwaveav20dt.htm tube monoblocks, with a McIntosh 6100 pre-amp to my AR-4x's, and I'm loving them. ASL are designed in the US, but built in China, and while the build quality isn't anything to write home about, I think they sound great (disclaimer: these are my first tube amps). They certainly fall in your price range too, put them on your short list. Funny, I just read about a vintage Dynaco today, looks very interesting.
  3. Thank you for all the tips, I've tested the woofers and they seem to be correctly marked, next up I rewired the woofers, using solder in place of the wire nuts, finally I put the 25 ohm resistor across the tweeter - and it sounds sweet! This is what I heard before, although with only one tweeter, the new ones are much smoother and the bass is just there, sounding much bigger than the cabinets would allow you to believe! I'm still going to redope the cloth surrounds on the woofers (and then may refinish the cabs) but for now I'm just going to enjoy the sound, I'm really amazed at how much can b
  4. One thing, are the L-Pad attenuators - 15W Mono 3/8" Shaft 8 Ohm (http://www.parts-express.com/pe/showdetl.cfm?Partnumber=260-248) that I got correct? The person who sold me the 4x's was asking tonight if they shouldn't have been 4 Ohms instead of 8.
  5. @RoyC this sounds like it may be a way to go, so a 25 ohm resistor like this? http://www.parts-express.com/pe/showdetl.cfm?partnumber=004-25 and then placed across the L-Pad terminals for the tweeter? The L-Pad came with a schematic, but I'm sure the resistor won't - I can sketch out what I have. Even if this isn't the issue, it seems this may get things more in line with how things would be with the pots, so I may try it. Your comments about woofer polarity may be my issue...thanks, that's up next. @JKent how do I test the speakers with a battery? I *think* I had the positive and negative rig
  6. I bought a pair of AR-4x speakers that had a newer tweeter in one cabinet, and corroded pots on both, so I decided to rework the pair. I utilized new phenolic ring tweeters - 8 Ohm (http://www.parts-exp...tnumber=270-252), new solen 20uF 400V polypropylene capacitors (http://www.parts-exp...tnumber=027-582) and new L-Pad attenuators - 15W Mono 3/8" Shaft 8 Ohm (http://www.parts-exp...tnumber=260-248) in place of the corroded pots. While the high end is now very well defined, I'm missing the bass that made the speaker sound so full and smooth before I started working on it - overall the sound i
  7. Ok, I've emailed you Jeff - also, I changed the permissions on flickr to allow everyone to see the speakers, you should be able to see it here now: https://secure.flickr.com/photos/fak3r/7918317054/in/set-72157631130021902/lightbox/
  8. Ok, you are correct - it seems that I have two different years/designs of AR-4x, so having the matching speakers would be really cool. If you can put the woofer and tweeter in the same box that'd be great, this way I would have matching components on my pair. Don't over engineer the box, I'd think some cardboard wrapped around the speakers, then some newspaper to keep them in place would be enough padding. Let me know what you think and what I'd owe you, thanks!
  9. Thanks, I have just ordered the other parts I need for the refurb last night, and am just trying to figure out the last piece. Just so you know, the one above with the 'square' magnet is the one I'm taking out, the proper AR magnet is rounded on two sides, like this one https://secure.flickr.com/photos/fak3r/7918691280/in/set-72157631130021902/ https://secure.flickr.com/photos/fak3r/7918689514/in/set-72157631130021902/ < that is the one I'm looking to match.
  10. Jeff, were you able to sell the AR-4x yet? If not and you were still interested in parting it out I only need an original woofer. Here's the one I need to swap out. https://secure.flickr.com/photos/fak3r/7918317054/in/set-72157631130021902/
  11. I understand Jeff, thanks again for your efforts, and if you do get rid of it drop it off at a Goodwill store or something - that way someone will get some use out of it.
  12. Jeff - Yikes, so is that just for the box and packing, and then 25$ on top of that? Even without, I only paid 50$ for the pair of AR-4x I have here - but yes, I did pick them up in person. I'm sorry you had to run around to get all that info, tell you what, how about if you could just break out the woofer, tweeter and the electronics back panel and ship just those like you offered before? I hate to break things up, but in reality that what I would have done with the speaker once I got it, this way I can get a vintage tweeter and have a woofer and backpanel for reference against my pair. If you
  13. Hey Jeff, I'd like everything, the whole speaker, and let me know how much the boxes and shipping are, I'll cover it! Thanks again for taking this on.
  14. Thanks Barefoot1, I am located in St. Louis Missouri, and really appreciate this - I'm loving the AR 4xs I have, but already see issues with how the woofers were (not) resealed properly, so I'd like to have a 'reference' speaker to work from Let me know how much you'll need to ship, thanks!
  15. I am interested in buying this AR 4x, I just bought a pair of 4xs this week, and one needs a new tweeter/L-pad, etc, so having a full extra speaker would be perfect. Additionally, I'm really liking the pair I got and could see restoring more of these in the future. I'll pay shipping, please let me know.
