I have heard these numbers many times and have always wondered where they come from. I assume they are theoretical. My experience is much different. As I explained in the origianl post, my RF-7's are in my HT as the front/mains (although they are used outside some). The sitting position is +/- 15 feet from them. With the preamp at 0db using the two Adcoms (600wpc) I experience 100db to 107db (measured with an RS SPL meter) at the listening seat while listening to a variaty of rock/metal. I have always wondered why my "real life" measurements are so far from the theoretical. Anybody know? As I said the speakers usually only get driven really hard when they are outside and nobody is really close. However, as I say above I do not get anywhere near the volume levels (SPLs) you suggest and therefore they (the RF-7s) do on occaision get driven hard inside. I would love it if some one could tell me why my SPLs differ so from theoretic.
