Technical Information

As mentioned in the introduction of this manual, Blue Sky International's high
performance to cost ratio is based on a philosophy that says that inexpensive
products should NOT be made from "inferior" components. This counter
intuitive attitude means that the highest quality components and manufacturing
techniques available are used in all aspects of the development and production
of this reference quality monitoring system. The specifications say it all, these
speakers are not toys - they are tools. We hope this new set of tools serves you
for a long time and that all the components, engineering and manufacturing
resources that have been used to make them shines through in every day use.
This next section outlines the components, specifications and performance
data that make this product such a uniquely high value.
In order to continually improve all of its products Blue Sky reserves the right to
change these specifications without notice.
