The cabinet construction is an important part of the design of these loudspeakers and differs in various ways from those
from other manufacturers' philosophies. It is all too easy for someone who has built speaker cabinets in the past to decide
to change something during construction because it worked for another design. This should not be the case when
constructing these cabinets and would undoubtedly result in an inferior loudspeaker.
Despite what you may think, the guitar like structure of our cabinets greatly enhances efficiency, dynamics and sparkle
and sounds less colored than the alternative methods, which generally just move the resonant frequency and amplitude of
the energy lower down in the spectrum, which in most cases is more audible, mainly because this also increases the
duration of the resonance. Our belief is that the shorter the duration of the energy is, the less likely it is to interfere with the
immediacy of the original transient.
A Note about Cabinet Material
Audio Note have fairly recently changed the materials that the cabinets should be made form. The enclosed cabinet plans
may still direct you to construct the outer front, back, top, bottom, and sides from either chipboard or MDF. Since these
plans were originally drawn, however, we have changed our recommendations for all of these to be made from 13-ply
Russian Birch Ply. All of our production speakers are now made from Baltic birch plywood.
The materials that are specified for internal bracing and sub-baffle, etc. may still be of the specified materials.
Handling
Care should always be taken when handling the drivers. You should only hold them by their frames or magnet assembly.
It is easy to, for example, accidentally put your finger through the paper cone of a woofer if you are not holding it correctly
because of their top-heavy nature.
The tweeter too is a soft domed tweeter. That means that the central dome can easily be distorted by attempting to hold it
by its dome.
