Frequency Response
18 Hz - 100 Hz
Power Line Voltage
US model
120 VAC 50/60 Hz
International model 230 VAC 50/60 Hz
Dimensions
11" x 11" x 11"
Weight
48 lbs
Finish
Black anodize and black lacquer.
Line power consumption:
600 W average, 18 Hz to 80 Hz, at absolute maximum continuous output.
8 watts at idle.
2700 W peak, time limited basis.
Output levels:
Greater than 110 dB peak SPL (includes room gain) from 18 Hz to 80 Hz.
A typical Sunfire subwoofer can be expected to ‘best’ its specified minimum peak SPL by several decibels.
Total Harmonic Distortion
Typically less than 1/10 of the fundamental between 18 to 80 Hz.
Input sensitivity for full output:
250mVrms from left input with volume control at 0dB, 60mVrms with volume control fully clockwise*
0.75Vrms from right input with volume control at 0dB, 200mVrms with volume control fully clockwise*
Input impedance:
12 kΩ for
15 kΩ for
Driver:
Extra large magnet and long throw mechanical design yield very high back- emf. The result is extraordinarily high operating efficiency – that is, more acoustic output for each watt of input.
Internal system gain:
50dB from left input jack to speaker with the Bass Level control at 0dB, 62dB with the control fully clockwise*
40dB from right input jack to speaker with the Bass Level control at 0dB, 52dB with the control fully clockwise*
*The Sunfire Subwoofer utilizes differential gain on the left and right inputs to retain both L+R and
