Yamaha YTR-8445 Xeno Series Professional Trumpet
Annealed bell
Yamaha employs special computer-controlled annealing equipment to ensure that the end result of this heating and cooling process is a consistently superior sound.
Hand-lapped pistons and slides
Hand-lapping pistons and slides ensures an absolutely perfect fit and seal between the pistons and casing or slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.
New mouthpiece receiver length
Enhances the responsiveness of the instrument.
Improved braces between valve castings
Add vibrancy and "life" to the sound of the horn.
Hand-hammered one-piece bell
A one-piece bell has an axial (lengthwise) seam, making it a continuous extension of the instrument's material. This results in pure, uniform resonance and superior tone. A hammered yellow brass bell produces a perfectly-balanced tone with quick response and extra presence due to advanced manufacturing.
Pressure-formed tubing
Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.
Laser-fused pluzuma-welded bell
A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations.
Metal thickness
The heavyweight trumpets have heavier metal through the instrument than the standard weight trumpets. Thicker metal helps the trumpets deliver a darker tone that does not break up with volume.
Specially treated metal
Through research, Yamaha designers have developed a process for treating metal that enables the heavyweight trumpets to deliver more power, better control, and richer sound.
