fied by NWAA Labs (www.nwaalabs.
com) using their proprietary MACH
testing system. All data is collected and
analyzed according to ASTM, ISO and
AES standards using EASERA, TEF and
MLSSA. Full balloon data including both
phase and magnitude is compiled into
a variety of formats including EASE 4.x,
GLL and CLF.
Architectural Specifications
The loudspeaker shall consist of one
305 mm (12 in) low-frequency trans-
ducer and one 35 mm (1.38 in) high-
frequency transducer with a frequency
dividing network installed in a ported
enclosure. The low-frequency voice
coil diameter shall be 35 mm (1.38 in).
The low-frequency transducer shall
have treated fiber cone material with a
treated cloth surround. The high-fre-
quency transducer shall be constructed
of Mylar material.
