| Also, a big, big, BIG part of dB output is speaker efficiency. 100w will theoretically give you a 3dB increase in volume over 50w - not a lot, but noticeable. You could easily lose that advantage by using inefficient speakers (say, as speaker efficiency of 98dB instead of 101dB). Losing 6 - 10dB is generally perceived as a 50% reduction in volume. |
