MIL-DTL-10911/8C
Frequency response: Within the limits of figure 2; 0 dB = 94 dB (see figure 2) relative to 20 micropascals (µPA)
(0.0002 dynes per square centimeter) between 200 to 5,000 Hz.
Harmonic distortion:
Dash number 01: 1 percent maximum.
Dash number 02: 5 percent maximum.
Cold resistance: The chamber shall be maintained at -80 degrees F +0, -5 degrees F for 24 hours and then
stabilized at -65 degrees F +0, -5 degrees F.
Solderability (dash number 01): Applicable.
Vibration, high frequency (dash number 01): Method 204 of MIL-STD-202, test condition D.
Shock (specified pulse) (dash number 01): Applicable.
Marking:
Part Identifying Number (PIN): M10911/8-01 or M10911/8-02 as specified.
Date code (dash number 01): Applicable.
Interchangeability: The loudspeaker M10911/8-01 is interchangeable with the LS-455/U.
NOTE: Impedance variations may be accomplished by either the use of voice coils wound to meet the specified
impedance, or the installation of impedance matching transformers, providing other performance characteristics
are not adversely affected.
The margins of this specification sheet are marked with vertical lines to indicate where changes from the previous
