  2. Rectilinear Research Corporation - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_Research...

    The Rectilinear speakers were typically, but not always, of ported design and finished in walnut with fabric or fretwork grilles. Many models featured one, or sometimes two, rear tone controls. The company offered some of their models as kits and "semi-kits". [23] Later models (1971 - approx. 1977) include: [24] 2; 4; 4.5; 5

    en.wikipedia.org/wiki/Swan_Electronics

    The Swan 500 was a more costly version of the 350, with higher output power and more operating features. Although they lacked the higher selectivity and tuning accuracy of higher priced transceivers, each performed solidly as a basic SSB station. They both used an outboard AC power supply with a built-in speaker, the model 117C and its variants.

  7. Loudspeaker measurement - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker_measurement

    A typical top-end speaker, driven by a typical 100watt power amplifier, cannot produce peak levels much above 105 dB SPL at 1 m (which translates roughly to 105 dB at the listening position from a pair of speakers in a typical listening room). Achieving truly realistic reproduction requires speakers capable of much higher levels than this ...

    "S9" signal strength, a strong signal, on the S meter of a typical ham or shortwave radio receiver: −80 dBm: 10 pW: −100 dBm: 0.1 pW: Minimal received signal power of wireless network (802.11 variants) −111 dBm: 0.008 pW = 8 fW: Thermal noise floor for commercial GPS single-channel signal bandwidth (2 MHz) −127.5 dBm: 0.178 fW = 178 aW

  9. Electrical characteristics of dynamic loudspeakers - Wikipedia

    en.wikipedia.org/wiki/Electrical_characteristics...

    At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity. The back EMF generated by this movement is also at its maximum. The electrical impedance of the speaker varies with the back EMF and thus with the applied frequency.
