nominal diameter, with a bolt pattern diameter of 440mm (17.3 in.), a
approved equivalent. The loudspeaker shall have a 460mm (18 in.)
nominal diameter, with a bolt pattern diameter of 440mm (17.3 in.), a
weight of 16.5kg (36.4 Ibs.), and a depth of 202mm (7.95 in.). The loud-
speaker shall have a rigid diecast aluminum frame that shall permit front
or rear mounting. The loudspeaker shall have a 600 watts, AES
Standard power-handling capacity and a uniform frequency response
from 20Hz to 3,000Hz, with a recommended crossover frequency of
speaker shall have a rigid diecast aluminum frame that shall permit front

Standard power-handling capacity and a uniform frequency response
from 20Hz to 3,000Hz, with a recommended crossover frequency of
1,000Hz 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 ohms. The loudspeaker shall
employ a low-mass 100mm (4 in.) diameter voice coil of edgewound
copper-clad aluminum ribbon of 30mm (1.2 in.) winding depth, on an
aluminum coil form, operating in a flux density of 13,600 gauss. The
