8.4 Testing and Maintenance of the system
General: Geo is a precision piece of equipment and requires regular attention to maintenance in order
to give long and reliable service.
Rigging
NEXO recommends regular testing of loudspeaker rigging components, preferably using a suitable test
rig coupled with a visual inspection.
Fasteners: there are several critical points in the LS18 and GEO M6 cabinets.
Of primary concern are:
a) The grid screws attaching the grid to the cabinet
b) The machine screws attaching the connecting plates to the cabinet.
c) The screws attaching the directivity flanges to the front of the cabinet.
These fasteners should be regularly checked and tightened as necessary.
Cleaning: The exterior of the cabinet and the rigging system can be cleaned with a damp cloth soaked
in mild soapy water. On no account use solvent based cleaners , which may damage the finish of the
cabinet
After cleaning, the rigging system must be treated with a suitable lubricant to prevent rusting. NEXO
recommends the use of Scottoil FS365 which is a water-based lubricant with a mixture of machine oil,
surfactant and anti-rust treatment.
Acoustics
NEXO recommends periodical check of impedance and frequency response by using FFT analyse
software such as Systune, Smaart, WinMLS or equivalent.
