Bookshelf Speaker Reviews

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the The Sixes Speaker System (purple trace). The right channel was measured at a distance of 1 meter with grille.

The Sixes’s listening-window response (a five-point average of axial and ±15-degree horizontal and vertical responses) measures + 1.19 /– 3.79 decibels from 200 hertz to 10 kilohertz. An average of axial and ±15-degree horizontal responses measures +1.33/–3.99 dB from 200 Hz to 10 kHz. The –3dB point is at 47 Hz, and the –6dB point is at 43 Hz.—MJP
