Satellite Sensitivity: 91.5 dB from 500 Hz to 2 kHz

Surround Sensitivity: 85.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Cinema 330 LCR speaker (purple trace), UltraCube 10 subwoofer (blue trace), and Cinema ADP 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 Cinema 330's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.52/–1.93 decibels from 200 hertz to 10 kilohertz. When orientated horizontally, an average of axial and +/–15-degree horizontal responses measures +2.47/–2.32 dB from 200 Hz to 10 kHz. The –3-dB point is at 103 Hz, and the –6-dB point is at 91 Hz. Impedance reaches a minimum of 3.67 ohms at 98 Hz and a phase angle of –41.06 degrees at 179 Hz.

The ADP's three-face averaged response measures +1.93/–1.30 dB from 200 Hz to 10 kHz. The –3-dB point is at 137 Hz, and the –6-dB point is at 117 Hz. Impedance reaches a minimum of 4.85 ohms at 429 Hz and a phase angle of –25.64 degrees at 302 Hz.

The UltraCube 10's close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 28 Hz and the –6-dB point is at 26 Hz. The upper –3-dB point is at 117 Hz with the cutoff frequency control set to maximum.—MJP
