Which of the 12" Brit speakers have the highest sensitivity? Looking to get max. volume out of an old Watkins Westminster. Cheers.
Sensitivity won’t tell you how loud and clear the speaker sounds to the human ear. That has to do with how much energy is in the 2~5kHz range. My guess is it’s between the Reaper HP and the Retro 30. The Retro may be a tad louder there, but you might prefer the warmer and less-aggressive Reaper HP.
This is such a complex topic!
