After watching Erin's video at Erin's Audio Corner about the differences between the criteria when selecting speaker for home theatre use and for music listening, I thought I'd open a discussion here to see what other people thought. In summary, Erin pointed out that for home theatre preference should be given to the following metrics:
- Speaker Output - Capability of handling louder volumes without compression and distortion
- Early Reflections Directivity Index - Relatively smooth line so that speakers can be EQ'd
- Linear Frequency Response - Erin makes an interesting point that people are more likely to be distracted by the action on screen so less likely to notice small deviations from the ideal curve. Anyway, if a speaker has a relatively smooth ERDI you can smooth out the response with EQ.
