Low Frequency Augmentation Series
Low Frequency Augmentation Series CODE 9B Specifications
A Note on Loudspeaker Specifications
It is a fact that while technical specifications are definitive; performance specifications are not. A speaker will perform differently subject to the constraints of its acoustic environment. When producing performance specifications, we believe they must represent the ‘real world’. We also suggest they be used as a guide only to the potential of a specific system. Therefore our performance specifications are produced, as a result of ‘real world’ testing, conservatively and with the goal of publishing useful data as opposed to marketing hyperbole.
