COLT Duo Acoustic End-button 90º

FASTER COLT DUO – Acoustic End-Button – Cello, has been developed from the FASTER PRO violin model and adapted to the acoustic characteristics of the cello. It features an elaborate, compact, and complex design that enhances the cello’s sound and tonal quality, combined with increased harmonics and improved acoustic emission.

By incorporating two specific silver tubes with internal compressors, the FASTER COLT DUO eliminates the residual air generated inside the cello’s soundboard, which limits its vibration capacity. It reproduces the vibrations of the lower area of the cello’s soundboard and other adjacent parts, generating a significant amount of acoustic power and contributing to the growth of harmonics, which are reinforced by increasing the intensity of the emerging air collected by the two silver tubes.

FASTER COLT DUO substantially inhibits vibration dispersion. works on the cello as an “all-in-one”:

• Enhances radiated energy.
• Amplifies sound production and acoustic projection.
• Distributes and organizes the frequency spectrum.
• Offers high acoustic stability under pressure and humidity variations.
• Increases harmonic production.
• Expands dynamic range.
• Increases timbre quality.
• Facilitates playing.
• Increases response speed.
• Reduces, in most cases, the production of wolf tones.
• Eliminates, in specific cases, the production of wolf tones.
• Prevents the loss of a large portion of the acoustic energy produced by the cello as well as the transfer of unwanted frequencies.
• Transmits the recovered energy, acting as a passive amplifier.

The COLT DUO is the ideal complement to the FASTER Artica, Dorna, and Meiga acoustic end pins for cello, as well as the BELTON acoustic stoppers. The combination of these elements undoubtedly offers an abundant amount of quality sound and great playability.

When you need to install your COLT DUO on a different cello, simply purchase a replacement COLT Cone, adapt it to the new instrument, and attach your COLT DUO
