108IM/NAT
The 108IM/NAT features an 8” (203mm) low frequency driver and an ETS based high
frequency compression driver. The 108IM/NAT HF driver is a very high performance and
medium format design. The 108IM/NAT is supplied with two high frequency horns, both of
which are fully rotatable and interchangeable. The ETS-64 is a 60 degree by 40 degree
wave guide and is mounted in the enclosure as supplied by the factory. The 108IM/NAT also
includes an ETS-105/60 horn that features a 105 degree by 60 degree acoustical radiation
pattern. The procedure for changing the high frequency horns is found on the One Systems
web site in the documentation section under the “tech papers and install guides” tab. (One
Systems Interchangeable High Frequency Horns (For 108IM loudspeaker).
The 108IM/NAT is a high performance system specifically designed for use in indoor
swimming pool environments. The design features a peak power handling rating of 800
watts and is available in an 8 ohm (lo Z) configuration only. There are only two mounting
points (AL-6XN) and the 108/NAT may be suspended using the supplied “U” bracket only.
(Note: there is a third point on the rear of the enclosure for use as a secondary safety.)
The 108IM/NAT is supplied with an external weather cover and IP68 gland nut for simple
wiring. The input is via a barrier strip. The enclosure is available in white color.
The 108IM/NAT is a closed box design. This acoustic configuration allows for simple low
frequency equalization using mixer strip EQ or other shelving style filters.
112IM/NAT
The 112IM/NAT features a 12” (305mm) low frequency driver and an ET based large format
high frequency compression driver. The 112IM/NAT HF driver is a very high performance
large format design. The 112IM/NAT is supplied with a high frequency horn that is fully
rotatable and interchangeable. The ET64 is a 60 degree by 40 degree wave guide and is
mounted in the enclosure as supplied by the factory. The 112IM/NAT can also be fitted with
the ET-105/60 horn that features a 105 degree by 60 degree acoustical radiation pattern (the
ET-105/60 is not included in the factory supplied 112IM/NAT, but may be ordered from One
Systems at no additional charge). The procedure for changing the high frequency horns is
found on the One Systems web site in the documentation section under the “tech papers
and install guides” tab (One Systems Interchangeable High Frequency Horns for 112IM,
115TW and 115RW horns loudspeakers). This same procedure should be followed for the
112IM/NAT.
The 112IM/NAT is a high performance system specifically designed for use in indoor
swimming pool environments. The design features a peak power handling rating of 3200
watts and is available in an 8-ohm (lo Z) configuration only. There are only two mounting
points (AL-6XN stainless steel) and the 112IM/NAT may be suspended using the supplied U-
bracket only.( Note: there is a third point on the rear of the enclosure for use as a secondary
safety.) The enclosure is only available in white color.
The 112IM/NAT is supplied with an external weather cover and IP68 gland nut for simple
