CROSS FIELD ARRAY-2 (CFA-2)

Long Throw/High Intelligibility

All-Weather Loudspeaker System

V100/2015

The One Systems Cross Field Array-2™ (CFA-2) was designed to provide very

high intelligibility and acoustic output where long throw requirements are

specified. The CFA-2 is a nominal 55 degree horizontal by 30 degree array that

features a fully rotatable high frequency horn/waveguide. This allows the CFA-2

to be used in either a vertical or horizontal orientation and still allows the desired

coverage patterns. The high frequency configuration consists of two large format

close-spaced compression drivers coupled to a 2” (50.8mm) constant directivity

horn. The low frequency configuration consists of 4 bandwidth optimized 10”

(254mm) diameter woofers in a 2 x 2 array. The CFA-2 is ideal for both

outdoor/direct weather long throw applications and indoor applications in high

ambient noise environments. Typical applications are football and soccer fields,

baseball fields and large theme park environments. Indoor environments such as

basketball arenas and natatorium installations are well suited due to the ultra-

high system intelligibility.

In order to achieve maximum system performance the CFA-2 should be high

pass filtered using a 4

order (24dB/octave) high pass filter set to 80Hz. This

filter frequency can be set using the One Systems SF-4 High Pass Filter system

or by using any high quality DSP based loudspeaker processor. High pass filter

frequencies as low as 60Hz may be used but maximum system dynamics and

headroom are achieved by using the recommended 80Hz filter corner frequency.

The CFA-2 is a direct weather design that features a three layer stainless steel

grill assembly. The enclosure design is a laminated fiberglass construction with

high safety factory structural rigging points molded in the enclosure shell. There

are 9 M10 rigging points and the system is supplied with a stainless steel “U”

bracket for simple suspension. The “U” bracket also includes a stainless steel

strap kit that allows the desired tilt angle to be set and maintained regardless of

wind loading.
