DIPOLE BAFFLE: ROUNDS

The Impulse response, Phase response and Frequency response shown on this page are from the RD-75 driver whose serial number ends in the digits '54'. The measurements were taken at distance of 2 meters from the baffle, and 1 meter from the floor. The baffle in the photo at left is not tilted, it is an artifact of the photo. Half-round wood moulding sections, 1.5" diameter, have been added to the edges of the 'BASIC' baffle as anti-diffraction treatment (NOT SHOWN IN PHOT0).

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.
