Introduction from the Manual:
Dear Friend:
Thank you for purchasing my Sunfire True Subwoofer Signature. I hope you enjoy it and the music it makes as much as I have enjoyed creating it for you.

The big breakthrough features of the subwoofer are its uncanny tracking downconverter and its long throw, high back-electromotive force driver. Taken together, they provide this subwoofer with as much bass as you could get from several 15 inch drivers mounted in a cabinet the size of a small refrigerator.

Bob Carver

Standout Features:
• 2,700 watt, high efficiency amplifier
• Very low distortion
• Long throw, premium quality drivers
• Mind-blowing output from a 13 inch cube!
• Automatic signal-sensing turn-on and standby mode
• Line level inputs
• Speaker-level binding post inputs
• Line level high-pass outputs
• Continuously variable phase control
• Continuously variable crossover 30 Hz to 100 Hz crossover control
• Continuously variable volume level control
• Soft clipping circuit allows graceful overload and prevents speaker damage due to clipping
• Gold-plated inputs and outputs

Sunfire True Subwoofer Signature - Manual

Amplifier Output
2,700 W rms (3.3 Ω impedance)

High Cut Filter
30 Hz - 100 Hz adjustable.

Frequency Response
16 Hz - 100 Hz.
Low pass is -6 dB @ 80 Hz

Power Line Voltage
AC 120 V, 50/60 Hz

13" x 13" x 13"

53 lbs

Black anodize and black lacquer.

Line power consumption:
800 W average, 16 Hz to 100 Hz, at absolute maximum continuous output.
8 W at idle.
2700 W peak, time limited basis

Output levels:
Greater than 116 dB peak SPL (includes room gain) from 16 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.

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

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:
54 dB from left input jack to speaker with the Bass Level control at 0 dB, 68 dB with the control fully clockwise*
44 dB from right input jack to speaker with the Bass Level control at 0 dB,
46 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.)
