Acoustic Loading provided by thelistening room will increase low frequency bass extension.3Distortion measurements performed with the input voltage necessary to produce thestated “A” weighted SPL level at the stated measurement distance. Distortion figuresrefer to the maximum distortion measured in any 1/10th octave wide band in the stat-ed frequency range.4Power Non-Linearity figures based on the “A” weighted deviation from linear increasein SPL with linear increase in input power (ie: power compression) measured after 3minutes of continuous pink noise excitation at the stated power level.JBL continually engages in research related to produce improvement. New materials,production methods, and design refinements are introduced into existing productswithout notice as a routine expression of that philosophy. For this reason, any currentJBL product may differ in some respect from its published description, but will alwaysequal or exceed the original design specifications unless otherwise stated.
