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*
0.75Vrms from right input with volume
control at 0dB, 200 mVrms with volume control fully clockwise*
Input impedance:
15 KΩ for
15 KΩ for
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
