L/R Sensitivity: 89 dB from 500 Hz to 2 kHz

Center/Surround Sensitivity: 89 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Artis Baltic Evolution L/R (purple trace), Altura Largo subwoofer (blue trace), and Artis Baltic Evolution Centrale center/surround (green 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 Artis Baltic Evolution’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.10/–3.68 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 84 Hz, and the –6-dB point is at 73 Hz. Impedance reaches a minimum of 4.02 ohms at 230 Hz and a phase angle of –63.17 degrees at 136 Hz.

The Artis Baltic Evolution Centrale’s listening-window response measures +2.54/–4.24 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.64/–4.11 dB from 200 Hz to 10 kHz. The –3-dB point is at 79 Hz, and the –6-dB point is at 69 Hz. Impedance reaches a minimum of 4.12 ohms at 235 Hz and a phase angle of –62.80 degrees at 139 Hz.

The Altura Largo’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 45 Hz and the –6-dB point is at 34 Hz. The upper –3-dB point is at 147 Hz with the Crossover Frequency control set to maximum.—MJP
