Specifications

Amplifier Output
2,700 watts rms (3.3 Ω impedance)
High Cut Filter
35 Hz - 100 Hz Adjustable.
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 funda-
mental between 18 to 80 Hz.
16
Measurement method is near field, dual
microphone technique. Distortion
decreases with decreasing level.
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 Line-Level inputs
15 kΩ for Hi-Level inputs
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 L-R
information.
