In Reply to: Cable article link posted by sbrians on September 30, 2013 at 10:38:55:
" Common listening levels are 60 to 70 dB SPL and, in typical home environments, require the power amplifiers deliver a few tens of milliwatts to the speaker ... Crest factors (the ratio of peak power required by transients to nominal signal power) range from 10 to 20 dB..."
The article claims typical listening levels are 60 - 70 dB SPL? That may be OK for solo harpsichord music, but hardly for a Mahler symphonies. I listen to these at row 5 concert volume. This means 80 - 90 dB SPL in fortissimo passages, with instantaneous peaks 20 to 30 dB higher.
After such a monumental disconnect, is there any point in reading the article further? The author seems to be in an entirely different sonic reality from me. I have 7 drivers driven by seven amplifiers and a total of over 1000 watts behind them and a rated peak SPL at 1m of 118 dB.
