1.5.3 Loudspeakers
Various types of loudspeaker arrays can be used in sounds systems using the PA250/700 amplifiers.
They are identified by the style and number of drivers (and bells) in each speaker array as shown in Table
1. As a guideline for system configuration, there should be a minimum of 1 speaker driver/bell assembly
for each 100 watts of amplifier power.

Efficiencies
The higher efficiency rating is due to more concentrated sound patterns and lower, more efficient power
conversion at each speaker driver. The larger speakers can also accept more power from the amplifying
system and may show an even better efficiency rating than these figures indicate.
1.5.3.1 TS92-02XN
The two-bell speaker array is widely used in airborne applications where its light weight and small size
are important considerations. While its output efficiency is not equal to that of the larger loudspeaker
types, it performs well on small and medium-sized aircraft. The size and weight of the two-bell speaker
often permits it to become a permanent installation in the aircraft.
1.5.3.2 TS92-04XN
The four-bell loudspeaker is almost universally chosen for portable sound systems. The greater
efficiency compensates for the additional weight compared to the two-bell speaker.
1.5.3.3 Multiple Speakers
The TS9X is designed to be assembled in groups of two, four or more. This permits the use of multiple
amplifying systems for higher sound levels and greater distance.
