The company also produced a tilted speaker stand, the "Rectilinear Dispersion Base", intended to be used with the Model 5 speaker. [25] Although the Rectilinear speakers were distributed through a nationwide network of up to 400 dealers, most of their sales was generated on the East Coast. [26]
The first and simplest method is using a surround sound recording technique—capturing two distinct stereo images, one for the front and one for the back or by using a dedicated setup, e.g., an augmented Decca tree [20] —or mixing-in surround sound for playback on an audio system using speakers encircling the listener to play audio from ...
Thiel Audio first exhibited at the Consumer Electronics Show in 1977 (the year the company was commonly stated as being founded, although they had been selling since 1976) [5] with the introduction of the 01 full-range speaker. A year later, in 1978, the model 03 introduced the principles of time, phase, and frequency coherence, which would ...
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.

Most such speakers have an internal amplifier and consequently require a power source, which may be by a mains power supply often via an AC adapter , batteries, or a USB port.

Network speakers are also known as IP speakers. [1] In many cases the IP speaker is created from an IP audio endpoint — a device with the requisite network connection and ability to process audio packets, but without the actual physical speaker portion — that provides amplified audio to a conventional loudspeaker or unamplified audio (i.e ...
The permanent magnet upgrade of the 601 was released in 1944 as the 604, at which point the 601 was discontinued. [5] The 604 was the same basic design using a 15-inch LF driver, but with a larger 3" voice coil, individual Alnico V magnets for the LF and HF drivers, and a cast aluminum frame.
