This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the 532-LR L/R (purple trace), S-12 subwoofer (blue trace), 533-VAC center-channel speaker (green trace), and 534-SS surround speaker (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 532-LR's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +0.71/–2.82 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 85 Hz, and the –6-dB point is at 71 Hz. Impedance reaches a minimum of 6.81 ohms at 230 Hz and a phase angle of –38.80 degrees at 123 Hz.

The 533-VAC's listening-window response measures +1.71/–3.94 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.30/–4.16 dB from 200 Hz to 10 kHz. The –3-dB point is at 75 Hz, and the –6-dB point is at 57 Hz. Impedance reaches a minimum of 5.91 ohms at 2.3 kHz and a phase angle of –44.87 degrees at 93 Hz.

The 534-SS's three-face averaged response in dipole mode measures +1.55/–7.25 dB from 200 Hz to 10 kHz. The –3-dB point is at 104 Hz, and the –6-dB point is at 90 Hz. Impedance reaches a minimum of 7.28 ohms at 2 kHz and a phase angle of –48.41 degrees at 136 Hz.

The S-12's close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 38 Hz and the –6-dB point is at 26 Hz. The upper –3-dB point is at 94 Hz with the crossover control set to maximum.—MJP
