Yes I agree but I've found speaker efficiency ratings to be a cruel mistress. I know they are all doing 1m/1w testing but some speakers are just louder in person than others with the same rating. Likely due to dominant or deficient freqs in each speaker and our perception of loudness. But isn't that what really matters in the end?
V30s are 100dbs but sound like they're 103dbs.
Texas Heats are 100dbs but sound like they're 98dbs.
CL80s are 98dbs but sound like they're 100dbs.
The Jensens are 96dbs but sound like they're 98dbs.
My G12T75s are 97dbs but sound closer to 96dbs.
My Veteran 30s are 98dbs but sound like they're 100dbs.
Again, freqs play a role in perception, but my perception is really all that I care about. I've found that just because a manufacturer says one speaker is the same loudness as another that it doesn't always translate to being true when standing in front of them playing your own rig.
