TOA fb-120b Brochura

A system is configured by vertically stacking four 
speaker modules with a total driver complement of four 
woofers and 12 tweeters positioned along the baffle 
surface. This configuration allows the variable directivity 
control and low-frequency dispersion control 
comparable to using a large constant-directivity horn 
speaker. A choice of four directivity angles — 15, 30, 45 
and 60 degrees can be employed as needed. For 

instance, a specific directivity angle, or each module can 
have its directivity independently set for a specific 
coverage requirement. When two or multiple modules 
are connected to configure an arc, they effectively 
function as an immense single speaker controlling 
directivity for considerably lower frequencies. As a result, 
public address functions demonstrate optimal 
intelligibility even in environments with long reverb times. 

Whether mounted on the wall or ceiling, the HX-5 is 
remarkably free from the comb filter and interference 
effects often encountered with other speaker designs. 
It can therefore produce more low frequency output 
even when mounted on the wall or ceiling.

Compared to many other speaker designs, the HX-5 
Series is remarkably easy to install in several ways. It 
can be hung easily with chains, strong wires and 
cables using the accessory brackets. There are also 
options for hanging with a pre-install frame by itself or 
configured with a subwoofer. There are also other 
options including ceiling and wall brackets as well as 
an adapter for use with a dedicated stand.

The HX-5 Series can also be used with a MT-200 
matching transformer.
