Distributed System Design (DSD) v3.6.2

The DSD program is a system design engineering tool that calculates and displays the number of ceiling and/or pendant loudspeakers needed to cover a room.

The user inputs a rectangular room with the approximate floor space of their project, along with the ceiling height (or trim height for pendant speakers). They select a starting-point loudspeaker and tap setting, and a density (to set the allowable sound level variation within the space). The DSD program computes the resulting number of speakers that are required for covering that listening space, along with a general layout in rows and columns and the target spacing distance between speakers. It computes the resulting performance parameters: Maximum continuous SPL for music and/or speech, maximum continuous peak SPL, expected level variation within the space, and the recommended amplifier power to utilize for powering the system. The Subwoofer Utility suggests a model and quantity of subwoofers to go with the system for instances where subwoofers are desirable.
DSD allows the user to change the design for “what if” scenarios: What will happen if we change the design to a different loudspeaker model, to a different tap setting, to a different density factor, etc? What happens if we trim the pendant speakers at a different height? What impact would different changes have on the number of speakers required, the layout distance between speakers, the resulting sound level, the level variation throughout the space, the required amplification, etc?
DSD gives the system designer the information they need for specifying their distributed loudspeaker system design.

CSC Ceiling Speaker Configurator Software v2.1

Custom Subwoofer Enclosure Design

CSC is a general sales estimation tool for basic projects. It comes up with a few ideas about which ceiling speaker could be used and approximately how many. This free utility program helps select the most economical JBL ceiling speaker to use based on various characteristics of the project, based on desired music level (for music systems) or background noise level (for paging systems).
The intention is that the use will then model the project more completely in the DSD Distributed System Design software (above) to determine how/whether the various possibilities from CSC might work for the project.

If you use Boxnotes to generate your cutting list, see the Speaker Building page for assembly sequence.
For some ideas on reducing the impact of resonances, see the Damping Treatments page.
A Resonances Experiment was conducted to determine what type of resonance occurs between the driver and a wall.
