There are speakers on this list that really exceed THX's and the SMPTE Standards, but if you are single factor weighting for high output, you will be disappointed.
I cannot say this enough, "Trust your ears."
Thanks. And yup, it's a big challenge. Consider this more of a, "Consolidated and sorted marketing data focusing on high output speakers."
Completely different than, say, data-bass.com with its measured data on subwoofer performance.
As always, a prospective consumer should look up trusted reviews, get input from real owners, and try to audition the speakers, in theirs or someone's equivalent space, if possible.
The utility of this spreadsheet is in presenting the marketing data, adjusted where possible, such that their spaces are being compared to eachother. And you can discount speakers that even the lying bastards in the marketing department don't claim good output.
For instance, if Paradigm's Series 7 Center 3 was advertised as only having 90dB anechoic sensitivity, and 93dB in-room, and able to handle 175w program, we can figure...
- 100w from a typical receiver would only get you 102dB
- That 100w is about 2/3rd of its own program watts rating
- The 212w it'd take to reach 105dB from 12ft is above what its published rating will allow. You're right, that's probably thermal. It's much worse in terms of distortion.
- The higher SPLs, if they can even be generated, are probably full of distortion.
So this is not a high output speaker, as pitched by their marketing department. If you want to listen at -5 or have a large space, this is not the speaker for you.
