 The pat-

ented Manifold Technology

®

 technique shall

be exploited and result in a power-handling

capacity of 600 watts per EIA Standard RS-

426. The average axial sensitivity shall be

105 dB SPL at 1 meter with 2.83 volts ap-

plied. The frequencies above 1,250 Hz shall

be produced by the supplied Electro-Voice

HP640 TransPlanar 

TM

 constant-directivity

horn with user-selectable driver combina-

tions.

The horn bell manifold chamber and back

covers shall be constructed of fiberglass,

foam and polyester resin. Two steel mount-

ing rails shall be provided to coaxially mount

the Electro-Voice HP640 horn. The horn

shall have an integral rear mounting bracket

made of black powder-coated 10-gauge steel.

Brackets shall be provided at the front of the

horn to stabilize and aim the MH6040AC.

The horn shall be 149.9 cm (59.0 in.) high,

99.1 cm (39.0 in.) wide, 153.4 cm (60.4 in.)

long and weigh 75 kg (165 lb).

The horn shall be the Electro-Voice
