One of the most sought after and best speaker AR made in this era. Second only to the AR3.
Gorgeous wood finish and grill fabric combination makes this the best looking package.
All drivers are in perfect working condition and have been thoroughly tested though the frequency range in our lab.
The woofers have been re-foamed in order to ensure another 20 years of reliable use. The potentiometers were cleaned and are super quiet.
The cabinets are simply stunning. No deep or noticeable scratches anywhere which is pretty rare for a speaker this age. The labels in the back are mostly intact although look a bit rough.
Acoustic Research AR-3a
The AR-3a is a three-way speaker and measures approximately 25” x 14” x 11½ ” inches and weigh about 46lbs each. It´s cabinet is made of real walnut veneer, grills are mostly cream colored. Each speaker has a 12 inch woofer, a dome midrange and a ¾ inch dome tweeter. High and mid-frequencies can be additionally adjusted at the back of each speaker. I can recommend to place the AR-3a´s on small stands, in this case solely to keep them a little cleaner and safer.
The sound of the AR-3a´s is very warm, but clear. Considering the fact that the speakers are nearly 50 years old, their bass is strong too. However, not rock or heavy bass music, but music with classical instruments or in general classical music lets these speakers shine. A big pro for these speakers is the huge variety of replacement parts available.
R-3a Quote from 1970
A quote from the original Acoustic Research owner´s manual: The Ar-3a is the best home speaker system we know how to make. It has been designed to reproduce music as accurately as present day knowledge of acoustics and electronics permits. In addition to incorporating the 305mm (12in) bass driver with which AR introduced its acoustic suspension systems to home listeners, the AR-3a was the first speaker system to use two miniature hemispherical speakers developed by AR to give better midrange and high-frequency response. The new miniature speakers offer an unprecedented degree of accuracy in their respective ranges.
The design of such small speakers – one is only 19mm (3/4 in) in diameter – although technically difficult, allows the laws of physics to operate to the listener´s advantage. While larger speakers must beam high frequencies straight forward, AR´s hemispheres instead spread these frequencies through a wide angle, considerably improving the realism of music reproduction for listeners in all parts of the room." (Quote out of my old AR-Manual, 1970ies)

WHO WE ARE
SkyFi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of select high-end audio equipment. We only buy equipment the we admire and are passionate about. No mid-fi, no gimmicks, no junk.
Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. If it does not meet or exceed the original manufactures specifications, it will not be sold. We are very selective about the equipment we purchase, focusing on mostly analog, high-build quality, American, and European built units.
Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Pro-Ject Audio Systems, and Sony ES, we have access to OEM parts, service, and support. If you are local and looking for new equipment from the above-mentioned manufacturers, please drop us a line as we can arrange both sales and professional installation in the tri-state area.
We do not accept or review any offers that do not go through the official Audiogon system. We have too many items for sale and it’s nearly impossible to keep track of offers outside of the official system. Please don’t message, email, or text any offers.
If you do not see a “Make an Offer” button, it means we are not considering any offers on that item.
We prefer working through PayPal which allows you to use a credit card or bank transfer. We do not charge extra for any payment fees if you purchase the item at the asking price. You can also send us a personal check (which will need to clear before shipping), certified check, money order, or wire transfer. International clients without access to PayPal should use a bank wire transfer.
If you are picking up an item we do not accept PayPal. You must pay in person with cash, certified or bank check, or wire transfer. If you make a PayPal payment and are picking up the item, it will be returned.
TRADE IN POLICY
We accept trade-ins of equal or lesser value under certain conditions. Simply ask and let us know the exact model, condition, and the accessories that are included (such as the original box, remote, cables, manual, etc.). We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. and will typically pass on displays, projectors, receivers, dated surround processors, and mid-fi equipment of any type. We will offer a fair value for your equipment, but keep in mind we are running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment. If you are looking for top dollar we suggest attempting to sell it directly to an end user on your own.
SELL US YOUR GEAR (Working or Broken)
We will also purchase your used or broken gear and arrange pickup if you are in our local market. Just drop us a note for a quote but be sure to include the condition and what is included.
HOW TO VISIT US
We are currently operating from a residence in Ridgewood, NJ. You are welcome to make an appointment if there is a piece of equipment you would like to see in operation before or after purchase. We have a well-equipped, dedicated listening room with tons of equipment of all makes and models. We are not a store, so please don’t make an appointment if you are just curious as to how a speaker or piece of equipment sounds. In essence, no tire kickers please.
If you are in NYC and cannot make it out to Ridgewood, we can arrange pickup in Union Square (14th Street) after the purchase. You can call or text 646.852.2073 with any questions or to schedule an appointment. We can also arrange to install, calibrate, and tune the gear in your listening room if you are local to the area. This is super useful when purchasing large speakers or heavy amplifiers. It is also great for ensuring your new turntable is setup correctly in its final resting place.
