Sunfire True Subwoofer Super Junior - Manual (Page 16)

User's Manual 16
Specifications
Amplifier Output
1,500 Watts rms (4.6
Ω impedance)
High Cut Filter
35 Hz - 100 Hz adjustable. The
crossover can be bypassed by rotating
the crossover frequency control fully
clockwise.
Frequency Response
22 Hz - 100 Hz
Power Line Voltage
AC 120 V/60 Hz
Dimensions
9" x 9" x 9"
Weight
29 lbs
Finish
Black anodize and black lacquer.
Line power consumption:
300 W average, 22 Hz to 100 Hz, at
absolute maximum continuous output.
1200 W peak, time limited basis
Output levels:
Greater than 108 dB peak SPL
(includes room gain) from 25 Hz to 90
Hz
A typical Sunfire subwoofer can be
expected to ‘best’ its specified minimum
peak SPL by several decibels.
Input sensitivity for full output:
240mVrms from left input with volume
control at 0dB, 90mVrms with volume
control fully clockwise
*
0.48Vrms from right input with volume
control at 0dB, 180mVrms with volume
control fully clockwise
*
Input impedance:
30K
Ω for Line-Level inputs
5.6K
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:
42dB from left input jack to speaker with
the Bass Level control at 0dB, 54dB with
the control fully clockwise
*
36dB from right input jack to speaker
with the Bass Level control at 0dB, 48dB
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.
