ATSC/DVB-3/SDI User Manual P/N 821557 Rev-A Section 3: Technical Information General Technical Observations General Mechanical Observations Elimination of cabinet and component sympathetic vibrations (resonances) requires considerable attention to mechanical details. Because of this, and the physical constraints of the speaker’s acoustic enclosures, even minor changes to any of the mechanical details of the unit can seriously impair its acoustic performance. This especially applies to the speaker baffles.
