Yamaha YSP-4300 Soundbar System Test Bench

Test Bench


This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Yamaha YSP-4300 Soundbar (purple trace) and subwoofer (blue trace). The left channel was measured with grille at a distance of 1 meter. The YSP-4300 Sound Bar's listening-window response (a five-point average of axial and +/-15-degree horizontal and vertical responses) measures + 2.88 /- 3.99 decibels from 200 hertz to 10 kilohertz. The -3dB point is at 202 Hz, and the -6dB point is at 174 Hz.

The subwoofer's close-miked response, normalized to the level at 80 Hz, indicates that the lower -3dB point is at 33 Hz and the -6dB point is at 29 Hz. The upper -3dB point is at 187 Hz. —MJP
