DEAR POSSIBLE & POTENTIAL BUYERS. IT DOES NOT COME WITHOUT POSSIBLE / POTENTIAL FAULTS THOUGH I WOULD SAY VERY VERY RARE. I HAVE ADDRESSED THIS AT THE END OF “DESCRIPTION OF ITEM”. PLEASE TAKE A SECOND OR SO TO REVIEW. THANK YOU FOR YOUR UNDERSTANDING ON THIS. Rare AR-4x Acoustic Suspension Loudspeakers Model L-1579. By Acoustic Research of Minnesota. One Pair Matched Speakers – Please read this full listing. The AR-4x is the successor of the prior popular AR-4 Model made by Acoustic Research Company. The AR-4x originating and coming out in late 1965 and early 1966 and beyond. The AR-4x originally had 2 1/2? Tweeters. The AR-4x received outstanding reviews and is even today famous for its sound quality. The AR-4x model was changed to the AR-4xa speaker by the Acoustic Research Company around the 1973, which were not well received overall. While some AR-4x units were finished with a walnut veneer and white cloth speakers, the favorite among users were actually the unfinished birch or pine cabinets. The company was never sure why this was excepting the fact that the company surmised the owners would rather finish the speaker cabinets to their own taste or match their home decor. Vinyl LP players of the era favored the sound coming from the AR-4x. I took pictures of sides and want tp note the top and bottom are in similar condition. These are heavy and well made. I would class these as shelf speakers. I found these on a back shelf in my heated and air conditioned workshop. They were setting on the back shelf in sealed garbage bag for a long time. That was until I moved and opened up the bags they were sealed in. I “kind of” remember them and having them in my Library Room at one point in time. However it has been so long ago and so many other stereo systems since then. I pretty much remember zero about them or why I switched out or anything other wise with regards to them. 19 inches tall and 10 inches square. As I remember zero about these and have no way of testing these. So please understand this. View Pictures for True Condition of the exterior of the Item(s). Naturally unsure of condition internally as I can not see inside. Most of which I feel is just Common Sense. Item(s) listed herein may have some degree of aging, use, wear, yellowing, patina and so on just from the fact is it old (or used or both) and the degree of whichever will apply, if any, will vary from item to item. Prop’s used in pictures to show size of item(s) or similar are not included in the sale. Just the item specifically listed for sale is. Please view all pictures of the item. Then make your final decision on the item based solely on Picture(s). I try as honestly as possible to describe the item as perfect as possible. I may unintentionally miss something or make an error. I do not do this for a living. HERE IS HOW I HANDLE THIS. In Cassopolis, Michigan at an agreed time. You have to pay first. All items Are Subject to Prior Sale. In doing this there is the very very very rare remote chance an item may sell on more than one site the same day which I think you would agree. Though very rare it COULD happen. This has taken away my option of choice. I do not favor this policy. I have been getting emails asking where my listings went on the last day of the listing and thought I had better explain why? I just like to be strait upwith potential buyers. May your days be blessed and those you care about well. I TRY TO KEEP IT REALLY SIMPLE. A BUSINESS FOR ME. I WILL SELL ITEMS FOR FRIENDS OR FAMILY. I MAKE NO COMMISSIONS ON THOSE ITEMS. I JUST SELL THEM. IN ADDITION IN 30-40 YEARS OF LIVING IN THE SAME VICTORIAN HOME THAT HAD MANY BARNS/OUTBUILDINGS I HAVE ACCUMULATED A LOT OF, WELL, I WILL CALL THEM MY “COLLECTIONS”. DOWNSIZING BY CHOICE TO A SMALLER HOME I HAVE A LOT OF “STUFF” AND “ITEMS” TO SELL. I do not consider this ethical nor fair to other possible buyers. (AT END OF LISTINGS THAT DO NOT SELL). (MAKING AN OFFER ON AN ITEM). I do not feel it is fair to others who may have viewed this item, or are watching an item that is listed. (THE ABOVE COMMENTS ARE NOTHING PERSONAL). It is nothing personal. ALL DESCRIPTIONS ARE HONEST AND TO MY BEST ABILITY. CHECK OUT MY REVIEWS. THEY SPEAK FOR THEMSELVES. Some examples would be a “coin”, “deck of cards” or similar. If there are pictures of them they ARE NOT included in the sale. They are there for size reference only. Only the item being described is what is offered for sale in the description of the item itself. This is pretty much common sense but thought I should make note of this. No exceptions will be made to this. LAOS OR NORTH VIETNAM. It is 100% the Buyers Responsibly to have their address correct within this System. Will not be issued. There will be no exceptions to this. This means you must come here and pick the item up at your expense or you must make arrangements with some third party to pick it up on your behalf and 100% at your expense. Just a Comment on Vintage items. Because I like old Vintage items. VINTAGE, RETRO, ANTIQUE & OLD ITEMS THEY ARE SO COOL. Please remember that Vintage and Antique items will show some wear, blemishes, and imperfections that they have acquired though the years. Old magazines, books, publications, booklets and manuals may come with wear, age spots & page discoloration. Some may have a slight age or. It’s a natural process. I collect or have collected many Vintage items over the years and I personally feel this adds to their character, charm and shows that the background and history of the pieces as being authentically old and thus making them more in demand, collectable and desirable to those that enjoy and/or collect them. Remember that even a vintage item in really good condition is old and it may not function as well as when it was originally made. Plastic type and other items can change color and/or weaken over time because of light, pollutants, heat, humidity and other items in the air. So if you intend on using a Vintage item, please be aware of this, and be careful. We can not control how you use them. They may be more subject to breaking just because of the fact they are old. We are not perfect and if we miss something we apologize in advance and just know it was not intentional. As with all the items we sell, we sell these items As IS and with all faults “if any”.

Pair of vintage AR-2a speakers, all original components, one woofer is bad and both crossovers need work. All other components test good. I have carefully removed both grills and they are both in tack. All badges are still attached to grills. Enclosures are a little rough but can be refinished. If you are familiar with these speakers you know that the level pots on the crossovers are a common problem and usually need to be replaced.

Acoustic Research AR4x Speakers TESTED AND WORKS PERFECTLY FINE. Has some blemishes(scratches and chipped edges, wear and tear on the grill/screen)(see photos). Photos serves as item description too. I pulled the grills to show surrounds still good and no dings. These grills were glued on and were a bit hard to come off. Unless they are glued back, they will come off from time to time, but will be easier to maintain should they ever need a speaker replacement. Just lay on back and put a dab of silicone or rubber cement in each corner and sit a book on top until dry.
