W stands for watts:another measurement of electrical power. One watt is equal to one volt times one amp of energy per second. Don't be mislead by wattage specifications. All things being equal, a good, expensive 50W amplifier will outperform a cheap, marginal 75W amp. Here's why 2. Warmth 3. Watt-The basic unit of power. From Ohm's Law we learn that power (measured in watts) dissipated by a load is equal to the voltage placed across that load multiplied by the current flowing through that load. (e.g., Whenever a current of 20 amps flows through a resistor with 12 volts across it, that resistor will have to handle 240 watts of power.) 4. Watt 5. Wattage-Is the unit of power used to rate the output of audio amplifiers. For a wattage number to have meaning the distortion level and impedance must also be specified. 6. Watts 7. WAV 8. Wave-A single oscillation in matter (i.e., a sound wave). Waves move outward from a point of disturbance, propagate through a medium, and grow weaker as they travel farther. Wave motion is associated with mechanical vibration, sound, heat, light, etc 9. Wave Table Synthesis-A technique for generating sounds from digital signals. Wave table synthesis stores digital samples of sound from various instruments, which can then be combined, edited, and enhanced to reproduce sound defined by a digital input signal. Wave table synthesis reproduces the sound of musical instruments better than Frequency Modulation (FM) synthesis. 10. Waveform: 11. Wavelength-The distance between one peak or crest of a sine wave and the next corresponding peak or crest. The wavelength of any frequency may be found by dividing the speed of sound by the frequency. 12. Wavelength: 13. Weighting:When laboratory measurements are taken of audio gear, the literal, "true" figures obtained often do not reflect the anomalies introduced by human perception. In these cases, the measurements obtained may be mathematically modified, or "weighted" to take into account the peculiarities of human hearing. A common example is "A-weighting", a curve applied to sound pressure levels to more accurately reflect our loudness perception. Other types of weighting compensate for the ear's frequency response, distortion tolerance etc. 14. Whisper-15-25 dB 15. White Noise:-Random noise with equal energy per frequency is called white noise. It tends to sound very bright and "hissy" due to the unique characteristics of the human ear's frequency response curve. Each ascending octave contains twice as many frequencies as the next lower one, resulting in a significant "build up" of energy in the higher octaves. 16. Wide-Bit Stream Processing: 17. Windings:The wire in a voice coil that is wound around the former (also called a bobbin) to create a coil. Generally, any coils in a transformer, motor, or as an inductor. 18. Woofer:-A speaker, (driver), used for low-frequency reproduction. Usually larger and heavier than a midrange or tweeter. 19. Woofer (Subwoofer)-The bass and lower midrange sounds are reproduced by the woofer. To operate efficiently, a woofer's cone should be made of material that is stiff, yet lightweight. Cones made of polymers, polypropylene, light metals, or poly mixed with other materials including carbon strands and metals, provide excellent sound, and stand up to the heat, cold and moisture that car speakers face daily. Paper cones treated for moisture resistance also do a good job, and are usually very efficient. For car usage, untreated cones should be avoided. The term "Subwoofer" came into common parlance as a result of the need for marketing departments to boost the "heavy hitting" image of their woofer products. Most such subwoofers are more dependent on the accompanying electronics than on the woofer itself. It was a campaign so successful, it is now as difficult to find a woofer as it is to find a "regular strength" antacid tablet. But as far as describing a particular type of Driver, the term is virtually worthless. The ludicrous extent to which the trend has gone is illustrated in the recent appearance of 4 inch "subwoofers." Study the ratings, specifications, and construction of any woofer you are considering, to see if will be appropriate for your system. In constructing your system, remember to start with the goal first, then the woofer and enclosure, and finally, the amplifier. Everything must work together, and fit together as one coherent system, if you are to be successful. One area in which the term "subwoofer" does have some authentic application is in the popularity of dedicated low range speakers called powered subwoofers (usually incorporating an amplifier and Crossover) that are used with home-theatre systems to boost the low-end response. 20.
