[QUOTE="JimJ, post: 7948871, member: 555251"] No. 1) Sensitivity ratings need to be taken with a huge grain of salt. What impedance are they using? Is it specified at 1W/1m, or 2.83V at whatever distance they want? Make sure you're comparing values on the same scale. 2) Power compression. Once you put enough power into a speaker, at some point you'll no longer have a linear increase in SPL. 3) Probably won't matter with only a 3dB difference in sensitivity, but if you're looking at a large difference (85 to 95, for example), the enclosure requirements will likely be different as a lot of different tradeoffs were made in the design.
