This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Imagine T3 L/R (purple trace), SubSeries 300 subwoofer (blue trace), Imagine C3 center channel (green trace), and Imagine S surround (red trace). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.
The Imagine T3’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +0.96/–2.72 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 28 Hz, and the –6dB point is at 24 Hz. Impedance reaches a minimum of 4.40 ohms at 90 Hz and a phase angle of –35.82 degrees at 71 Hz.
The Imagine C3’s listening-window response measures +2.10/–5.42 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.79/–5.83 dB from 200 Hz to 10 kHz. The –3dB point is at 55 Hz, and the –6dB point is at 48 Hz. Impedance reaches a minimum of 4.66 ohms at 992 Hz and a phase angle of –63.48 degrees at 134 Hz.
The Imagine S’s three-face averaged response in dipole mode measures +1.07/–5.29 dB from 200 Hz to 10 kHz. The –3dB point is at 95 Hz, and the –6dB point is at 82 Hz. Impedance reaches a minimum of 5.64 ohms at 221 Hz and a phase angle of –48.96 degrees at 136 Hz.
The SubSeries 300’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 23 Hz and the –6dB point is at 21 Hz. The upper –3dB point is at 133 Hz using the LFE input.—MJ
