[QUOTE="Ivan Beaver, post: 125853, member: 30"] Re: L'acoustics Dv-Dosc Installation - Recommandation So does that mean 106dB A continuous or peak? Is that 106 dBA or dBC? There is a BIG difference there. If you consider that "average" musical material has between 10-15dB dynamic range (peaks), then the system has to be capable of 116-121dB output at the back of the room. A "simple number" often results is a simple-easy to understand WRONG answer. YES- details matter. ESPECIALLY when asking if a particular product can produce a particular result. Accurately defining the target is VERY important. And not that anybody cares-but the A scale is only intended for usage below 85dB. Above that-the C scale is what should be used-at least by the people who write the standards of such things. The difference between A slow and C peak can be as much as 30dB. Which is only a factor of ONE THOUSAND. It takes quite a different system to produce one unit of measure vs the other. If you don't specify-then there is no telling what you may end up with. YOU may know what you are expecting-but different people may have a different thought/opinion. THAT is why the numbers are important. To translate into a language that everybody understands. That is my just being picky-but it IS important to understand the differences. [/QUOTE]
