    L710 conundrum????

    I have a pair of L 710's I just opened up. Just on inspection they did not look right. You can see from pictures that somebody had either salvaged or replaced speakers with realistic 6 inchers. The cabinets are in good condition, and everything works. So, do I part them out, or do I try and find 4 drivers? Any suggestions will be considered. Thank you in advance for comments.

    AR Connoisseur Mid Drivers Wanted

    Thanks Stimpy.I have shimmed the voice coil,and I am going to put the new surrounds on,and see if that fixed it.If not,the guy you recommended for repair,said,I should try to find replacements first , I would only do that if they were original to the model.Rob
  4. I am in need of one mid-driver ,Please contact me if you have one,or two available with price.If you have two that are reasonably priced,I can send you the ones I have that need to be reconed.(bad voice coils),Thanks,Rob
  5. Can any one Plesse tell me what capacitors are needed to recap these speakers?Thanks,Rob

    AR Connoisseur rebuild(capacitors)

    Well,I do not know that they need replacing.I just got them in.I usually gather information before actually doing the rebuild.I have two bad mid driver's with burnt up voice coils, So I was not able to hear them.When and if I sell them,I usually replace all capacitors.I will not sell a piece of equipment,not knowing it is fully up to spec.Most capacitors I have found,have a 20% +/- tolerance.I like to replace them with a 5% to 10% cap.I really love the older,well made pieces,I believe they should be as close,or better than original,when I am finished with them. I will pull them out,and test them of course,It just save me a little time to already know what I might be knowing,so I can source them before hand.Thanks,Rob

    AR Connoisseur rebuild

    Thanks Stimpy, I have done surrounds,and speaker realignment to several sets of AR speakers,but,on these,it looks like the material has become unglued from the card board tube.There also seems to be little rips in the material.I noticed rub marks also.I can not figure out what would cause this to happen.The rest of the drivers,and cabinets are in great condition,so thank you,I will call Bill,at miller sound.Rob
  9. I had previously bought some from a member.I am sorry,but I forgot his Name.Could some member have him contact me please.I should have bought twice the amount,Thanks,Rob

    DQ 18 bass driver identification

    Does anyone have a picture of the back(magnet) of a DQ 18 bass driver?Are there any identifying marks,stamps,or stickers?There is a pair I am trying to buy,I just want to be sure the driver are unmolested and original.I would have to drive 100 miles to pick them up,and the owner(2nd) does not know.Thanks for any help.
  12. Thanks Pete.I am just waiting for for an original early version with cloth surrounds.I spent so much time and effort to get them to this point,I am too stubborn to not complete them back to what they were before that dropping incident,thanks again,Rob
  13. Chris,You recently repaired my 2ax tweeter.Thanks,it works great.That same speaker fell from its perch.Now the bass driver buzzes,or barely works.So,I am also in need of a woofer.If you come across more than you need,give them my contact imfo.If you do,I will send you the blown speaker for shipping price.There are some on ebay,but they have been refoamed,and I am trying to stay original.Thanks,Rpb
  14. I am looking for both the woofers and one midrange for BA T 930 series two.Thanks,Rob

    Boston T 930 II Information

    Thanks,I know(I read) that Jerry helped design them.I would like to know what the individual speakers are supposed to be (on ohm meter) Every one I have questioned is either 4,or 6 ohm.I am very confused at this point.Rob

    Boston T 930 II Information

    I just came across a pair of B-A T 930 II.The tweeters work fine,but the midrange's and basses flutters and chirpped at just under 50 watts.All controls were flat.I know now the the bass speakers are transplants,they read low 5 ohm.I pulled one of the midrange speakers,it had Made in taiwan stamped on the back.I guess my question would be,what are the actual specs for the individual speakers? Also,I can not seem to find replacement speakers,even ones needing surrounds,Any help would be appreciated.Rob

    Boston T 930 II Information

    Thanks PeteB.I just wanted to make sure of speaker compatibility.I would like to put them back to original. I always look on ebay,I guess I will just keep looking,have not found any except other replacement speakers.I was not sure if other speaker models used the same drivers.Rob

    Lost AR-2ax

    Most of what you might be looking for is in the older posts.I am pretty new here myself,and I asked the same questions,Most of the subjects on your speakers ,will be here,in detail,with pics.Good luck.Rob
  19. I am always wondering if I am hearing things correctly.I used to have a very good ear.Now,I am again wondering?Where do you get Ear Glasses.I promise not to wear them in public.Rob
  20. I spent a lot of time thinking about the grills.Since they do not affect sound,should they not be appealing to the eye?The originals or prone to breaking and warping.I also understand keeping them as an original feature,true to the speaker.I made some frames for my 2 ax's out of 1/2" square dowels.I am just waiting for the material to finish them.I do have the originals,but they are in sad shape.I will post pics when finished.Now,I guess I will have to refinish the cabinets.Just my 2 cents.Rob

    2 ax replacement caps?

    I just recieved the new caps for the 2 ax's.Does it matter which end goes which way?I know the two ends of two capacitors are the common.Does the orientation matter?Thanks,Rob
