At Lange Loudspeakers SA, our ATTO loudspeaker features a meticulously designed high-frequency compression driver that leverages the inherent efficiency of magnesium dome technology. This high-end magnesium dome, typically found in premium dome tweeters, ensures superior sound quality and responsiveness.

Equipped with a powerful 15,000 Gauss magnet and high Xmax capabilities, our compression driver effortlessly reaches 1,200 Hz while extending its frequency response up to an impressive 28,000 Hz. The innovative three-channel circumferential phase plug further enhances performance, providing unparalleled clarity and precision in the high-frequency range.

Proudly imagined, designed, and manufactured in-house, the ATTO loudspeaker exemplifies our commitment to audio excellence, making it the ideal choice for audiophiles seeking exceptional sound reproduction.

The ATTO loudspeaker, coupled with our advanced waveguide technology, achieves exceptionally broad very high frequency (VHF) coverage, reaching frequencies up to 28,000 Hz, well beyond the human hearing threshold. With a mean directivity of 110° (-6 dB) up to 20 kHz and beyond, the ATTO stands out as one of the few loudspeakers in the industry capable of delivering such remarkable performance.

This unique driver and waveguide combination ensures a smooth, consistent sound dispersion, allowing for an immersive listening experience. Ideal for audiophiles and professionals seeking precise audio reproduction, the ATTO’s superior directivity makes it a top choice for high-resolution sound systems.

At Lange Loudspeakers SA, our ATTO loudspeaker features an in-house designed low-mid driver that exemplifies high-performance engineering. The driver’s CNC-manufactured chassis is meticulously crafted to reduce reflections from the loudspeaker frame back to the diaphragm, enhancing sound clarity

Our driver design incorporates a comprehensive array of refinements, ensuring reliable operation and simplified manufacturing. By addressing strict manufacturing tolerances, we optimize performance across our loudspeaker systems. The slug-type magnet is engineered for optimal efficiency, minimizing reflections towards the diaphragm thanks to its compact design and promoting superior coil cooling.

Strategically placed ventilation holes in the coil support minimize mechanical resistance (Rms) and enhance operational efficiency. The diaphragm is crafted to maximize frequency response, utilizing a transitional geometry instead of a traditional dome or cone shape. Constructed from anodized aluminum and paired with nitrile suspensions, the design effectively reduces Mms tolerance and maintains precision.

The absence of a dust cap further ensures minimal tolerances, while the CNC-manufactured frame facilitates precise component centering during production. This geometry effectively dissipates heat from the coil and promotes smooth acoustic energy flow, resulting in minimal reflections and superior sound reproduction.

Our low-mid frequency driver is a pinnacle of engineering, featuring a modern voice coil constructed with two-layer copper-clad aluminum wire for enhanced conductivity and efficiency. The driver is equipped with a high-performance slug-type magnet made from N52 grade neodymium, ensuring optimal magnetic strength and efficiency.

The one-piece oxidized aluminum diaphragm is designed with a transitional geometry, enhancing frequency response and minimizing distortion. Coupled with a nitrile suspension, these elements work in harmony to significantly boost overall performance while reducing variations in loudspeaker driver performance.

Every key component has been meticulously designed and manufactured in-house to ensure the highest quality standards, reflecting our commitment to audio excellence.
