Ask a question about this product

 

Thanks to ability to design and the development in mechanical engineering, CVL LEGNO was able to develop a particular technology, completely different from standard building techniques of building plywood shells for drums. Besides the design and the experience in the field of wood, CVL LEGNO is able to build directly into its factory machineries needed for construction of wooden drum shells. Shells made from this technology differ from those usually on the market, because they are made with a particular moulding, while usually the construction is assembling concentric cylinders, each of which forms with sheets of plywood jointed and folded to form a cylinder. If the conventional technologies obtains cylinders that have material discontinuity in radial direction than in circumferential, with CVL LEGNO’s technology the cylinder has a good uniformity, with a lower concentration of tensions training of the cylinder..

CVL LEGNO technology allows to build any diameter of the shell, even different thicknesses (from 2,5 to 12mm).

Moreover, while the conventional technologies require the use of generic plywood to make the shell and then the last sheet of veneer with the best wood, the CVL LEGNO ’s technology uses only the best sheets of wood at the same time forming the cylinder, with specific directions, according to conformation of the wood veneer

A CVL shell born from the choice of the best tree, the best wooden layers with the best wooden veneer for each of the essences used in CVL instruments. All this researches and works are done directly by CVL staff using the ISO 9001 quality certification

CVL LEGNO shells have successfully passed all tests as aging tests, high temperatures tests (inside a wave at 105 °C for 500 hours) to ensure to the customer an high standard of quality.  All CVL LEGNO drums are made entirely by a unique first quality essence of wood in order to ensure a sound well-defined, thanks to the same density of wooden layers and to the uniformity of the drums.
CVL LEGNO also made specific recordings and researchs in the field of audiometric engineer on its shells. Thanks to a sound engineer, CVL LEGNO recorded the power and harmonic sounds of all drum kits made by different woods, reporting all results in appropriate graphs.
All drums have the characteristic of a great attack with a well-defined and well-balanced sound, using different tunings of heads, more or less tighten, retaining a considerable power.
It is possible to change  in a simple way the sound range while maintaining a clear sound without losing the tuning or sound timber.
Audiometric tests have measured a significant wealth of harmonics, resulting from both a percussive intensity of media and strong beat. Beating the raw drum shell, you can hear a well-defined sound background.
Looking to drums with the same diameter, but made by different wooden essences, the sounds differ from each other, leaving to the wood its own timber. Between the wood essences, there are different impressions expressed in terms of harmonious composition and in terms of sound impact, as demonstrated on graphics.

The CVL shells are made using the strictly parameters of international certification ISO 9001:2008

ENVIRONMENTAL SHELL:

CVL warrants the provenience of woods used for its drums and it warrants the environment and re plant of wood plants.

CVL starts this project to achieve the production of shells with a lower environmental impact and to save the nature and plants, thinking to a future eco sustainable.

A project that continue using varnish and glue with small or none quantity of danger components.

WARRANTY CVL
warranties its shell 5 years for all production default thanks to the stricly production method and test to achieve a high sonour standard and a tuning endurance.

TRACEABILITY PRODUCT: CVL, thanks to the code inside the shell, can recognize the shell and add new shells in a second time but with same physical and sound features

WOOD TYPES: These wooden choices are important for the factory, because they allow to give the best instrument also to the most exigent drummer. CVL is continuously involved to find the best sound for the musician, to satisfy needs with a professional skill and competence.
