[QUOTE="Mark DeArman, post: 137991, member: 950"] Re: dB calculations I get the reasons. It's just for the type of work that I do, the comparisons work much better using a 1W fixed point. This is the number which is called out on the spec sheet as "the" sensitivity. The plot vs. frequency is relative to that one point, for the fixed voltage which is listed on the spec sheet. From a customer perspective, for the most part it leads to some numbers which are lower than other people get with 2.83Vrms as the stimulus. (I guess the marketing guys could complain, but since I write the spec sheets personally now... I got tired of them making things up. I look at some of the shit they made 10 years ago, and I can't believe anyone okay'd it.... uhg.) Basing them all on voltage does have the advantage, for the small end-user, that voltage clipping will most likely limit their output. So he can choose a box and amp combination easier. But most people probably don't think about it that way. [/QUOTE]
