The object of good cabinet design should be to achieve a quiet cabinet, not a dead one. Cabinet resonance is the primary and more difficult problem to control.
The more obvious internal features have to be solved, like internal vertical and horizontal bracing and forming compartments that are designed to achieve cabinet rigidity and isolation of drivers.
For some over than 20 years, Venture has used the approach of multiple laminates of solid hardwood to build up the outer walls of its speaker cabinets. Use of dissimilar materials in constrained laminated structures has been well established as an extremely effective method for damping vibrations in aircraft structures.
An improvement to the original multiple layer design was used for the Classic series of Venture speakers, where a heavy damping sheet was incorporated into the middle of the solid beech wood multi-layers.
However, by discovering the advantage of using alternating layers of HDF( High Density Fiberboard) with layers of solid hardwood in the laminate structure, this cabinet exhibits very low level resonances that are subdued and works in such a way that the cabinet does not interfere with the sound that the drivers produce. This approach is used in the Ultimate series of cabinets with excellent results for reducing unwanted vibration.
For years a high gloss finish with beautiful veneers and paints, has been the staple 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) to its cabinets, further controlling cabinet vibrations. This finish is 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 sound stage is noise free and the dynamics are preserved with superb focus of images and higher resolution of tones and sibilance.
Another area that is important to the cabinet design is the shape. Venture uses the V and C-shapes, both have their sides converge to a narrow front baffle, in order to minimize the baffle surface area and the subsequent sound wave reflections. Baffle reflections interfere with the wave launch of the drivers, causing some distortion of the sound, increasing noise floor and compromising the focus of images on the sound stage.
