Specifications
Amplifier Output
1,250 W rms (3.3 Ω impedance)
High Cut Filter
35 Hz - 100 Hz adjustable.
Frequency Response
18 Hz - 100 Hz.

Power Line Voltage
AC 120 V, 50/60 Hz
Dimensions
11" x 11" x 11"

removable fabric grill.
Line power consumption:
350 W average, 18 Hz to 100 Hz, at
absolute maximum continuous output.
8 W at idle.
Output levels:
Greater than 107 dB peak SPL
(includes room gain) from 18 Hz to
100 Hz. Measurement method is one
meter, anechoic, including room gain.
A typical Sunfire subwoofer can be
expected to ‘best’ its specified minimum
peak SPL by several decibels.
THD:
Less than 1/10 of the fundamental
between 18 and 80 Hz
Input sensitivity for full output:
250 mVrms from left input with volume
control at 0dB, 60 mVrms with volume
control fully clockwise
*
0.75 Vrms from right input with volume
control at 0dB, 200 mVrms with volume
control fully clockwise
*
Input impedance:
15 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:
46 dB from left input jack to speaker with
the Bass Level control at 0 dB, 56 dB
with the control fully clockwise
*
36 dB from right input jack to speaker
with the Bass Level control at 0 dB,
48 dB 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.
