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.

Low pass is -6 dB @ 80 Hz

Power Line Voltage

AC 120 V, 50/60 Hz

Dimensions

11" x 11" x 11"

Weight

40 lbs

Finish

Black anodize and black lacquer.
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 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:

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.
