Frequency response 

is 

measured in a spherical free-field environment, under 1 watt

is

mounted in an 80-liter sealed box The impedanced magnitude curve is measured

while the speaker is suspended in free air, with its cone in the vertical plane

The low-frequency loudspeaker shall be TOA Model HLS30S2-8/16 or
approved equivalents. The loudspeaker shall have 300mm (12 in.)
nominal diameter, with a bolt pattern diameter of 322mm (12.7 in.), a
weight of 11 kg (24.3 Ibs.), and a depth of 143mm (5.63 in.). The
loudspeaker shall have a rigid diecast aluminum frame that shall permit
front or rear mounting. The loudspeaker shall have a 300W AES
Standard power-handling capacity and a uniform frequency response
from 50Hz to 4,000Hz, with a recommended crossover frequency of
2,000Hz or lower to obtain smoothest overall system response. Band-
limited (100 to 800Hz) pink noise sensitivity shall be 98dB (1W/1m).
Nominal impedance shall be 8/16 ohms. The loudspeaker shall employ a
low-mass 72mm (2.8 in.) diameter voice coil of edgewound copper-clad
aluminum ribbon of 15mm (0.59 in.) winding depth, on an aluminum coil
form, operating in a flux density of 16,200 gauss. The voice coil shall be
driven by a powerful ferrite magnet. Effective moving mass shall be
0.055kg. The cone suspension shall be made of exceptionally high-
compliance, damped-cloth surround.

Distortion response is measured with a swept sine wave signal, at 30 watts (-10dB
power) & 1 meter, and while the speaker unit 

is 

mounted in an 80-liter sealed box.
