Note: Good coverage = ± 6dB; Better coverage = ± 3dB and Best coverage = ± 1.5 dB. Typically we recom- mend Better coverage but if cost constraints make this impossible for the customer, then use the Good cover- age. Best coverage is where you want very even coverage and typically either low or high SPL.

= Ceiling Height – Listener Position Spacing max = Hdiff x Speaker F value

Columns = Roundup ( room length / Spacing max )

Rows = Roundup ( room width / Spacing max )

Spacing L = room length / columns

Spacing W = room width / rows

First speaker is placed at (Spacing L/2, Spacing W/2)

Next column is placed at (Spacing L/2+ Spacing L) … and so on until all columns are placed Next Row is placed at (Spacing W/2+ Spacing W) … and so on until all columns are placed

To determine how many subwoofer you require for a room, the calculations are much easier. You determine the cubic feet of the room (L x W x H all in feet), divide this number by 15,000 and round up.

To determine the max SPL in the room, you need to know Hdiff in feet and the Max SPL of the speaker. Use the following Max SPL at 3 feet for each speaker is:

Speaker Type

Max SPL

 

 

PRi665CV

101 dB

 

 

PRi685CV

103 dB

 

 

PRi85SubCV

101 dB

 

 

Note: These are not the absolute max SPL for the speaker. These are guidelines to use for designing systems.
