QUALITY MANAGEMENT
Your Opus loudspeakers have been constructed to the highest standards of quality
throughout.
The acoustic components and the whole system have been manufactured to very tight
tolerances of +/- 1 decibel of sound pressure level for each driver throughout the operation
range of the unit.
All drive unit components are serially numbered and the original test record set for your
loudspeakers is retained on file in our factory quality control department.
This enables us to give a extended guarantee of identical replacement parts should they ever
be required.
A copy of these test reports is included in the back of this manual. These should be retained
for future reference.
A certificate of conformance to the original prototype specification, confirmed by the Opus
designer and engineering director is included in this pack.
