Using the Quam Speaker Coverage Calculator
Speaker Coverage Calculator
This app is designed to provide an estimated edge-to-edge speaker
coverage pattern. It is intended for estimation purposes only and
should be used as a guideline when estimating the number of required
speakers. There are many other factors that should be considered when
determining the required number of speakers for a particular
room.
Length: Enter the length of the room in feet
Width: Enter the width of the room in feet
Seated or Standing: Select
either seated or standing listening height. Seated height is 3.5 ft.
and standing height is 5 ft. When selected, the choice will be
dark blue in color.
Ceiling: Enter the ceiling height in feet. The calculation has a maximum ceiling height of 16 feet.
Speaker Model: Select the
speaker model series by tapping the model number. By tapping the model
number, a page of speaker series will open. Tap on the model number
series. When selected, the model will turn yellow in color.

From this page, a Web Link to the Quam website product page can be
opened.
Transformer Tap Settings: The
transformer tap settings will be displayed below the Speaker Model. The
selected tap setting will be dark blue. The tap selection is used to
calculate the maximum direct field dB-SPL level shown at the bottom of
the page.
Speaker Layout Data Results
Edge-to-Edge: The calculation
is based on an Edge-to-Edge speaker coverage pattern. Some critical
listening application may require more speakers to achieve center to
Center.
Number of Speakers: The calculation for the number of speakers placed the length and width of the room.
Corner Starting Position: This is the staring point from the corner of the room from the wall.
Spacing on Centers: From the
corner staring position, speaker will be placed on the length and width
axis this far apart. This calculation is rounded to the nearest 2
feet to account for ceiling tiles grid layout.
Total Number of Speakers: this
is the calculation of the number of speakers for the length of the room
multiplied by the number of speakers for the width of the room.
Max Direct Field SPL: This is the calculation of the coverage pattern, transformer tap setting, and the sensitivity of the selected speakers.
Info: Defines the input fields and output data.
Email button: Calculated data results may be emailed.
