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. You can constantly find replacement screens, refoam-kits (but you need to know how to refoam!) or little “AR-3a” logos on ebay. If you consider buying one of these vintage favorites you have to be aware that they can cost quite a bit of money and sometimes it can be beneficial, if you know how to restore vintage speakers, as many have worn down parts. A big plus is that there are many restoration guides, some of which are very detailed
