The H Series "Minimum Reflection" Advantage
Semi-Flush vs. Bracket-Mounted Speakers
The measured data below graphically illustrates the significant frequency response degradation
in the lower mid-range when mounting a speaker 5-20 cm (2-8 ") from a surface (typical with
bracket-mounted speakers). Surface reflections combine out-of-phase with the direct sound
H-1
and cause cancellations. The H Series semi-flush mounting (0 cm diagrams) minimizes the out-
of-phase reflections by eliminating the distance between the enclosure and the mounting sur-
face. See Frequency Response plots for H Series direct, reflected and summed response.
