Figure 13. R.5-66MAX Spec Sheet Frequency Response Graphs
FREQUENCY RESPONSE
(processed*)
COMMUNITY'S ALTERNATE APPROACH (continued)
Both R.5-MAX products also use 6dB of LF boost to create the “Processed” Frequency Response graphs shown on the
spec sheets. Figure 13 shows the response curves, with notation, for the R.5-66MAX and Figure 14 shows the R.5-66MAX
frequency response with and without the 6dB of LF boost applied:
As with the R2-MAX, the difference with and without the LF boost applied is fairly subtle and is an indication of Community’s
design philosophy of well-matched components. The LF boost simply serves to “square off” the response knee above the
high pass filter. The published R.5-MAX equalization curves contain an optional PEQ filter that adds 6 dB at 120 Hz. (In the
Resyn™ Software Loudspeaker Library for Community’s dSPEC226 processor, this LF boost filter is included, but bypassed
by default). In applications where the full output of the loudspeaker is not required, the designer may choose to include
the LF boost. However, this reduces the safe, equalized Maximum Output SPL by 6 dB. In the case of the R.5-66MAX, the
maximum output would be reduced from 130 dB to 124 dB.
We hope that this clear explanation of the R-MAX specification numbers and graphs, will allow the system designer and system
commissioner to have enough information to clearly state expectations to their customers and achieve the promised results.
