Up for sale here is a very nice pair of AR 3a loudspeakers. This pair was manufactured in June of 1974, a month before we opened our first store! Cosmetically we’d give them a 7.5 maybe even an 8 on a scale of 1-10. No real flaws to speak of but we tried to show the flaws they have in our pictures. Despite these minor cosmetic flaws they present very nicely. What was recently fixed on them: >Both woofers professionally refoamed Sept 2023 >All 4 level pots for the midranges and tweeters replaced Sept. 2023 with high quality controls. Speaker drivers are all original and they were tested very carefully after reassembling. They sound great and work exactly as they should! No long term guarantee beyond that. Nothing ever arrives from us damaged in transit as we take our packing very seriously! Since we’re now operating without a storefront we are unable to offer audition of the speakers. Thanks very much for looking.

We have for sale a properly working pair of classic AR3a loudspeakers. Rated at 4 ohms impedance they measure 3.4 and 3.5 ohms DC resistance which is normal. Serial numbers are 3a37950 and 3a4J525. They work very well and sound fantastic but please read all the details below. >Recently professionally refoamed woofers. >All drivers (speaker parts) work properly and are all original AR factory parts. >Level controls are very smooth and function perfectly. >Level controls are not original but ones our shop installed for a customer over 20 years ago. They work great but are not stock. >One of the woofers is an AR factory replacement. The magnet structure and frame look identical to the original. If you’re looking for that perfect, cosmetically mint pair these are definitely not them! Cosmetically we’d give them a 6 maybe a 6.5 on a scale of 1-10. Scratches here and there but nothing real serious. That being said they work great and we believe they’ve got lots of life left in them. No long term guarantee beyond that. If you live in within 50 miles from us (each way) in Central Berkeley we will also offer to deliver them to you curbside at no extra charge. We’d much rather bring them to you then pack them.

This is for replacement controls for AR’s early model speakers such as the AR-3, AR-3a, AR-2, AR-2ax, AR-4, AR-4x, AR-5, etc. This control is superior to the original control which AR used and was eventually utilized in the AR-3a Limited. It is heavy duty, has finer turns for better set ability, is ventilated for heat removal and has excellent contact life. It is an “L Pad” design which holds the resistance nearly constant while adjusting the driver balance. All controls on all early model AR speakers were the same, both the High Range and the Midrange. I use these in all my AR speaker restorations. I have been using these on a regular basis for over 10 years and have never had to replace one. Included is a set of instructions for change out. The only tools required are a solder iron, electrical pliers and adjustable wrench or pair of pliers. If you are tired of those original troublesome controls then these may be for you. As you will be removing the woofer to install these, I suggest you order a package or two of cabinet sealer found in Dept. OTHER SPEAKER SERVICE PARTS. Additionally, if you are considering replacing the crossover capacitors, now is the time while you are inside the cabinet. These are available in Dept. If you would rather avoid the task of soldering in the cabinet, we have now added completely solder-less kits for the AR-3, AR-3a, AR-4x, AR-2ax, AR-2a and AR-5 speakers. You will find them in our store listings under SPEAKER LEVEL CONTROLS. Recent feedback from one of our customers. Hey, Larry – got the speakers back together and held my breath hitting the start button…. Have to tell you – WHAT A DIFFERENCE!! I must have been missing a lot of music from the Hi/Mid’s esp. The highs prior to swapping. I can certainly tell a difference. So it was an endeavor worthwhile for sure. Please browse the rest of the store. We are constantly adding new items for the AR fan.
