As a classic three-way floor-standing horn tweeter speaker, Crane combines top-level design in one package.

Each channel has three ways and four units, with two beryllium diaphragm horn units and the other two titanium sandwich composite diaphragm cone units. Foiled beryllium diaphragms by Truextent® provide higher resolution and lower distortion. Those beryllium diaphragms are applied in the middle, tweeter, and super tweeter units. The invention patented by ESD, titanium sandwich diaphragms, is a unique horn tweeter speaker that is lightweight yet sturdy and capable of eliminating segmentation and phase distortion.

Field coil power supplies applying AI negative feedback technology can effectively cancel out dynamic suppression caused by eddy current, solving this century-old puzzle. Field coil speaker units all have a magnetic density of 2.2T. Powerful magnetic flux drives the speaker effortlessly. The carbon fiber horn is uncolored acoustically, providing a smooth mid-range for this horn tweeter speaker.

The cabinet is CNC precision machined from aero-aluminum. Along with reinforced linings and anti-resonance materials inside, these floor-standing speakers minimize cabinet sound distortion to the lowest possible level. Each component is enough to highlight the other system, but it’s just one element in this 100-102db speaker.

The built-in active crossover further allows the horn tweeter speaker Crane to adapt to different room conditions, handling spaces of all sizes or distances effortlessly. The innovative combination of active and passive crossover ensures seamless integration across the entire frequency range, providing a more natural and relaxing sound.

With extremely low distortion and high performance, Crane is one of the most competitive floor-standing speakers on the market.
