DSP System Selection - Stereo & Multichannel
Download this page (pdf)
Introduction
This DSP System Selection guide prevents monitors being used in rooms that are too large or at listening distances that are too long. The recommendation allows larger monitors to be used if the customer desires.
Selecting the Right Model
Use the following chart as a guide for product selection and follow these three simple steps:
- Calculate the room volume and find the highest row in the table column 'Room Volume up to' that is not smaller than your room volume.
- Measure the listening distance to the center of the listening area and find the highest row in the table column 'Listening Distance up to' that is not shorter than your listening distance.
- If there are two different rows selected in the previous two steps, select the models from the row that is lowest in the table, i.e. the larger system of the two.
Note:
a) If space or finances are limited, rear/side monitors can be compromised slightly by selecting the next sized model down in the range (use 8240A's instead of 8250A's).

DSP Monitor System Selection Table
- 1) If the system is planned to be eventually upgraded to surround, it is recommended to select the subwoofer model from the '5-channel surround' column for future SPL compatibility. In addition, selecting the larger of the two subwoofers will give additional headroom and lower distortion in a stereo system.
- 2) Additional subwoofers of the same type may be required in a larger room with bass heavy program material.
