Floorstanding Speaker Systems

Satellite Sensitivity: 88.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 88.5 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the TSS-SAT4000 satellites (purple trace), TSS-SUB4000 subwoofer (blue trace), and TSS-CENTER4000 center channel (green trace). All passive loudspeakers were measured at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The TSS-SAT4000's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.72/–1.10 decibels from 200 hertz to 10 kilohertz. The –3dB point is at 131 Hz, and the –6dB point is at 115 Hz. Impedance reaches a minimum of 4.72 ohms at 12.9 kHz and a phase angle of –55.24 degrees at 198 Hz.

The TSS-CENTER4000's listening-window response measures +1.67/–0.35 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +1.09/–0.87 dB from 200 Hz to 10 kHz. The –3dB point is at 131 Hz, and the –6dB point is at 115 Hz. Impedance reaches a minimum of 4.72 ohms at 12.9 kHz and a phase angle of –56.21 degrees at 198 Hz.

The TSS-SUB4000's close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 37 Hz and the –6dB point is at 30 Hz. The upper –3dB point is at 141 Hz with the low-pass switch set to off.—MJP
