User's Manual 16
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.
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 k
Ω for Line-Level inputs
15 k
Ω 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.
