Fundamentals of acoustics 41. ear is able to detect sounds with frequencies from 20 Hz to 20,000 Hz. Sound characterised by frequencies between 1 and 20 Hz is called infrasound and is not considered damaging at levels below 120 dB.
The Design Acoustics PS-10 is best operated close to ear height, although not necessarily against a wall. Its considerable depth may prevent its installation on normal bookshelves, since it will extend over the front of even a 12-inch shelf.
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.
You can find information about the original AR-3 speaker from 1958 in our review. When the AR-3a was introduced in the mid 60ies it took over the role of the AR-3. Acoustic Research placed a new set of smaller dome midrange and tweeter into the cabinets.
Crossovers of AR-3 and AR-3a are different: Mid / Tweeter: 1000 / 7500 Hz vs. 575 / 5000 Hz. The lower midrange of the AR-3a was better for dispersion. Overall it can be said that maintaining the original Acoustic Research AR-3 is more difficult than the newer AR-3a.
The Acoustic Research 2x and 2ax (AR-2x / AR-2ax) are based on the design of the AR-3a, but were marketed as a value product, which means price played a crucial role. Therefore it contains most of the typical elements and ingredients as the high-priced Acoustic Research speakers, but has a slightly lower performance.
