DIPOLE BAFFLE: 3 & SQUARE LEFT

The Impulse, Phase and Frequency responses are from an RD-75, serial number ending in '54'. The measurements were taken at distances of 1, 2, 3 and 3.5 meters, and 1 meter height. The baffle is named for the 3" base right-triangle added to the left side of the 'ROUNDS' baffle.

Details of the measurement process are to be found in the Measurements section. The required passive notch filter was in circuit with the driver during the measurement. Additionally, a non-standard slope 2nd order (12dB/oct) active filter set to a -3dB point of 150Hz was also in circuit. The rising phase response below 1000Hz reflects this fact.

Height: 75.6"
Top width: 19.25"
Base width: 22.5" - Sides~ 8" & 11"
Thickness: ~1.56" Half-round edges

The following comparison of the 1m, 2m, 3m and 3.5m responses of the '3&SQ Left' baffle are 1/3 octave smoothed in order to facilitate evaluation. The following individual plots of the distance measurements are 1/12 octave smoothed. They will look slightly different from that shown in the comparison.

1 meter response, 1/12 octave smoothed.

2 meter response, 1/12 octave smoothed.

3 meter response, 1/12 octave smoothed.

3.5 meter response, 1/12 octave smoothed.
