Vintage Acoustic Research AR28S HiFi Speakers

Vintage Acoustic Rese arch AR28S HiFi Speakers. In full working order with new rubber surrounds. The speaker surrounds are made of high quality rubber, pliable, anti-aging and durable. They are very close substitute(very flexible) for surround foams but with plenty of life in them. One corner of each cabinet is slightly damaged but has been filled up with wood filler and they are not visible from the front – see pictures. One AR badge is missing too. Comes with grills- front covers. The mid range, high range and the bass are wonderful, bass is deep, tight and controlled, although very powerful. One of the best little speaker ever. The Acoustic Research AR28S benefits of an upgraded ferro-fluid cooled tweeter and what AR eventually described as their”Universal” woofer coupled with a”New Look”. But it dawned on them eventually that the female in the house wanted a speaker to be a piece of furniture as much as a purveyor of sound. They put their heads together and came up with the”S” series designed to look and sound nice, they succeeded. Edgar Villchur, the founder of the original Acoustic Research Company invented the acoustic suspension (infinite baffle) principle in 1953, just as they invented the dome speaker. What AR had always been famous for was the neutrality of sound. A good speaker was good with everything and anything, either you play rock or classical music they deliver amazing sound. There is some grain of truth in AR’s motto” High Fidelity’. Type: 2 way, 2 driver loudspeaker system. Frequency Response: 50 Hz to 24 kHz. Recommended Amplifier: 100 W (maximum). Crossover Frequency: 2000 Hz. Bass: 1 x 200 mm cone. Tweeter: 1 x 25 mm liquid cooled dome. Enclosure: 18.1 litre, acoustic suspension. Finish: walnut grain vinyl. Dimensions: 544 x 298 x 199 mm.

Acoustic Research AR28S Speakers in Walnut, sequential serial numbers. 8 Drivers have been recently re-foamed to a very high standard without disturbing the dust caps, good for several more decades of enjoyment. Cabinets are in great shape for their age, a couple of scrapes, small split, the bottoms are in good shape too. The fabric is all original, as are the capacitors which tested perfect. Normally I would look to replace things but they look and sound great. I haven’t come across another pair in as good a condition as this. I’ve also been through the entire Teledyne era range of AR speakers. These produce some of the best sound thanks to the large soft-dome tweeters. Unfortunately the time has come to let go to some of my collection. You won’t find any modern speakers readily available like this anymore thanks to their sealed acoustic suspension design. Happy to answer any questions about them or give any advice regarding replacement capacitors or black grill cloth etc. Speakers can be seen and collected from Southampton (or Basingstoke with some notice). I can also deliver them for the cost of fuel. Will be posted ASAP. They are very heavy, 10KG each!
