THE UNVEILING OF A NEW SPEAKER SYSTEM | Kent Morris
Loudspeakers are mechanical devices . They push and pull like pistons in an engine millions of times over their lifespan . With a suspension system based on rubber or coated paper , eventually , the surrounds give way , or the voice coil gap is jumped , or any number of other problems arise . When the time comes , a new loudspeaker system purchase is in order . But knowing how to replace an ageing system is fraught with uncertainties and questions of budget , performance , reliability , and maintenance requirements . Fortunately , the current crop of loudspeakers is both versatile and cost effective thanks to technical innovations and the competitiveness of the market . Here are some ways to decide which replacement system is right for your church .
First , consider the appropriateness of the current system . Does it have complete coverage of the space ? Is there consistency across the seating area in terms of level and frequency response ? Does the system convey the reality of what is happening on the platform ? If the answers are yes , then the selection of a replacement falls simply to the new version of the old system , assuming it will fit in the space and falls within the budget . However , in the more likely scenario where the current system fails to deliver across the board , the process becomes involved , for a deficiency in current coverage can only be addressed through detailed analysis . The solution lies within modern predictive software and design . If the sanctuary plans are available in CAD ( Computer Aided Design ) form , they can be imported as . dwg files to serve as the basis for testing various speaker brands and models in the virtual world in order to determine the best choice for the real world . Practically every serious manufacturer offers the performance details of each speaker as determined in an anechoic chamber where reflections and room signatures are eliminated , making it possible to insert a given model into the software , such as Electro Acoustic Simulation for Engineers ( EASE ), where each speaker can be compared against others to find the best fit for a given space .
Second , after the best fit is selected , it needs to be confirmed as viable for power , fit , and configuration . In other words , if the system is self-powered , is there sufficient support structure and power at the hang locations ? If
