Viewing Distance Calculator
Scanning Frequency and Bandwidth Calculator
This calculator will compute the predicted maximum sound pressure level (loudness) at the listening position. Four pieces of information are required, plus one optional input:
Horizontal Scanning Frequency and Bandwidth Calculator
Projection Calculator Pro
Will your projector fit the available space? What about your screen? What about seating and room lighting? To find out, use our Projection Calculator Pro by following these 2 easy steps:
The Reverberation Calculator
This page will calculate reverb time for the home theate room you input here.
Room Mode Calculator
Wire Gauge Calculator
Type in the power output of the amp, the impedance of the cabinet or speaker, and the length of the speaker cable you want to run. The answer will be the gauge of the stranded wire you should use for the speaker cable. This calculator is limited to 500 watts, greater than 2 ohms, and cable lengths not to exceed 20 feet.
Amplifier Power Calculator
How big a power amplifier do you need to fill a venue with loud, clear sound? A louder sound system and a bigger room requires more power. Loudspeakers with high sensitivity need less power than loudspeakers with low sensitivity. Empirical evidence shows that peak power is really only about 1dB higher than continuous power, and depends on peak duration.
Screen Size Calculator
What's the right screen size for a particular viewing distance? What's the best distance to watch a certain sized tv? Since standard definition televisions always have a screen ratio of 3:4, and high definition (wide screen) tv's are always 9:16, you only fill in one field for the column and the rest will be computed. The number that you enter will appear in red. The calculated numbers will be black. Screen size calculations need to be adjusted to a size that is actually available from a manufacturer. If you use inches for your input value, the other measurements will also be in inches. The same is true for feet, centimeters, etc.
Note: The high def values are "ideal" because they don't take into consideration watching a standard definition show on the same set. The "compromise" values adjust the screen size or the viewing distance to improve the picture when a high def set shows a standard def picture.
