Bookshelf Speaker Reviews

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Stealth 8 L/C/R (purple trace) and Stealth 6 surround (red trace). These active/powered loudspeakers were measured at a distance of 1 meter and scaled for display purposes. Grilles are not included with either of these models, and all controls were set to the default (off) position.

The Stealth 8’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +0.99/–2.66 decibels from 200 hertz to 10 kilohertz. An average of axial and +/–15-degree horizontal responses measures +1.24/–1.89 dB from 200 Hz to 10 kHz. The –3-dB point is at 35 Hz, and the –6-dB point is at 32 Hz.

The Stealth 6’s listening-window response measures +1.36/–1.09 dB from 200 Hz to 10 kHz. The –3-dB point is at 38 Hz, and the –6-dB point is at 35 Hz. —MJP
