The loudspeaker driver's moving mass and compliance (slackness or reciprocal stiffness of the suspension) determines the driver's resonance frequency (F s). In combination with the damping properties of the system (both mechanical and electrical) all these factors affect the low-frequency response of sealed-box systems.
Off the Wall supports up to three players simultaneously (though most cabinets only support two). The game's graphics include many backgrounds modeled after modern abstract art . In spite of the identical title, this is a different game from the 1989 Atari 2600 cartridge release.
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.
A speaker enclosure using a passive radiator usually contains an "active loudspeaker" (or main driver), and a passive radiator (also known as a "drone cone"). The active loudspeaker is a normal driver, and the passive radiator is of similar construction, but without a voice coil and magnet assembly.
A driver is commonly installed in an enclosure (often a wooden cabinet) to prevent the sound waves coming off the back of the driver diaphragm from canceling out the sound waves being generated from the front of the subwoofer. A typical Hi-Fi subwoofer (r.), with the subwoofer loudspeaker built into a cabinet.
Death rates fell among highly affected HIV subpopulations. Medical breakthroughs have reduced death rates for Americans with HIV, including groups that are disproportionately affected by the virus.
The number of childfree women is at a record high: 48 percent of women between the ages of 18 and 44 don’t have kids, according to 2014 Census numbers. The Huffington Post and YouGov asked 124 women why they choose to be childfree.
