Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with 4-inch (10 cm) woofers and small tweeters designed for listening to music with a hi-fi system in a private home to huge, heavy subwoofer enclosures with multiple 18-inch (46 cm) or even 21-inch (53 cm) speakers in huge enclosures which are designed for use in ...
The horn-loaded subwoofers each have a floor mouth that is 2.2 square meters (24 sq ft), and a horn length that is 9.5 meters (31 ft), in a cavity 1 meter (3 ft 3 in) under the floor of the listening room. Each subwoofer is driven by eight 18-inch subwoofer drivers with 100 millimeters (3.9 in) voice coils.
With optimal out of phase designs, distortion is slightly reduced due to the cancellation of suspension and other driver non-linearities. [1] Because the impedance is also halved, the performance of an isobaric speaker is achieved with twice the power. The new efficiency is thus 3 dB lower than with one loudspeaker.
The 1925 paper [1] of Chester W. Rice and Edward W. Kellogg, fueled by advances in radio and electronics, increased interest in direct radiator loudspeakers. In 1930, A. J. Thuras of Bell Labs patented (US Patent No. 1869178) his "Sound Translating Device" (essentially a vented box) which was evidence of the interest in many types of enclosure design at the time.
The two most common types of speaker enclosure are acoustic suspension (sometimes called pneumatic suspension) and bass reflex.In both cases, the tuning affects the lower end of the driver's response, but above a certain frequency, the driver itself becomes the dominant factor and the size of the enclosure and ports (if any) become irrelevant.
A loudspeaker enclosure based on the concept was proposed in October 1965 by Dr A.R. Bailey in Wireless World magazine, referencing a production version of an acoustic-line enclosure design from Radford Electronics Ltd. [16] The article postulated that energy from the rear of a driver unit could be essentially absorbed, without damping the cone ...
