This. I have attended numerous live performances, and never has the sound reach 120dB. I don't sit in the front row, but that's because I don't think the performance sounds best there.

Jim states it much more eloquently than I, but in a nutshell it is because the high efficiency drivers he has tested don't meet his requirements for musical reproduction. I'm talking detail, timbre/tonality, accuracy, etc. There are trade-offs to high efficiency designs just like there are trade-offs to non-HE designs. Heck, speaker design is nothing but trade-offs; we just need to find the ones we're willing to live with. Me personally: I don't listen to music at 120dB, so my Salk speakers perform just fine.
If I had a dedicated HT in a very large room I'd use something else (again - design trade-offs).
It seems the pro high efficiency design fanboys have nothing better to do lately than to corrupt threads with hate towards non HE designs. It's kind of pathetic really... What's ironic is that Dr. Floyd Toole himself (a pioneer in this industry) says in his latest book that in all but very large rooms most traditional dome-style speakers can hit reference levels for short periods of time without adverse effects to the sound, and without the necessity of horns and such. He also states that such levels are not preferred by most people, and that HE designs are more likely to cause hearing damage to those that listen to them. But yet the pro HE design fanboys still push their agenda, claiming non-HE can't cut it. And yet the 2-channel industry is dominated by non-HE designs. Gee, I wonder why?
HE designs are great for HT, but the people that push only that design and insist reference levels are a must for movie watching are a small sampling of the masses; they are a niche group, but apparently also the most angry and pushy.
As mentioned already, the SS8's are 87dB sensitive, not 84.
