The object of good cabinet design should be to achieve a resonance free,
quiet cabinet. Cabinet resonance is the primary and more difficult problem
to control, once the more obvious internal features are solved, like vertical
and horizontal bracing and compartments are designed to achieve cabinet rigidity.
For some 15 years, Venture has used the approach of multiple layers of solid hardwood to build up the outer walls of his speaker cabinets. An improvement to that multiple layer design was used for the Classic Series of speakers, where he added a heavy damping sheet in the middle of the solid beechwood multi-layers. However, Venture recently discovered the advantage of using HDF (High Density Fiberboard) layers in between the layers of solid hardwood.
For years, a high gloss finish with beautiful veneers and paints has been a signature of Venture Speakers. Recently, Venture developed a way of applying a thick layer of a hard polyester high gloss mirror finish (circa 1300 microns thick), which further reduces cabinet vibrations.
The new finish responsible for a noticeable improvement in the focus of images, better micro dynamics and it enhances the beauty of the speakers.
Once a quiet cabinet is achieved, the background is darker and the micro-dynamics are preserved for superb focus of images and higher resolution of tones and sibilance. Venture has experimented with other methods of cabinet resonance control.
The use of heavy materials, such as metal and granite that have their own characteristic sound can induce a "cool" or "lifeless" sound print. As another example, the use of sand in the speaker walls can result in a "dull" sound print. In other words, these examples indicate that most cabinet designs have a way of manifesting peaks or valleys in the sound spectrum that complicates and compromises speaker design.
There is another area of cabinet design that is important, and that is the shape of the cabinet. Venture uses a V shape, where linear bevels converge to a narrow front baffle, in order to minimize the baffle surface area and the subsequent sound wave reflections.
A similar cabinet shape used by Venture is a C shape, with continuous curves that converge to a narrow front baffle, which also minimizes the baffle surface area. Baffle reflections interfere with the wave launch of the drivers, causing spurious distortions of the sound and reducing the coherence of the speaker.
