Soliloquy 5.3 loudspeaker Measurements part 2
Fig.5 Soliloquy 5.3, lateral response family at 50", normalized to response on tweeter axis, from back to front: differences in response 90 degrees-5 degrees off-axis, reference response, differences in response 5 degrees-90 degrees off-axis.
Fig.6 Soliloquy 5.3, vertical response family at 50", from back to front: differences in response 15 degrees-5 degrees above HF axis, reference response, differences in response 5 degrees-10 degrees below HF axis.
In the time domain, the Soliloquy's step response (fig.7) indicates that the tweeter is connected in inverted acoustic polarity, with a complete cycle in its output preceding the positive-polarity step from the woofers. The 5.3's cumulative spectral-decay plot (fig.8) is basically free from treble resonant problems—KR did note how grainless the speaker's presentation was.—John Atkinson
