Author Last Post

We’re moving and can’t take these great subs with us. Make any offer. Excellent condition!

 

Two subwoofers: One Sunfire True Subwoofer MK IV and one Sunfire True Subwoofer MK II, which was serviced at the factory for upgrade/update and is now equivalent to an MK IV, so they match.

SPECS:

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 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
