Price is for a pair of speakers.

DESCRIPTION

INDIANA LINE CONTINUES 3

Representing the latest iteration of the Tesi series, the Tesi 3 bookshelf model not only presents itself perfectly, but also delivers an attractive, balanced, clear and dynamic sound – unrivaled in its price class. The new models in the Tesi line boast innovative technical solutions that incorporate components proven in the latest flagship models of the Diva series, while maintaining a simple and versatile design. The Tesi 3 model is available in three color options – black oak, white and mocha, so it blends seamlessly into any interior decor.

Reinforced body, UNIVERSAL STYLE

The Tesi 3 model has an internally reinforced MDF cabinet. Compared to the Tesi 261 model, the dimensions have changed slightly - it is approximately 2 cm shorter and 1 cm less deep. The forward-facing bass reflex port facilitates room-filling and provides dynamic low tones. The midrange driver basket has a trim ring that contributes to the aesthetic appeal of the speaker. In addition, the Tesi 3 model has a magnetic grille and, like other models in the new generation Tesi series, features gently rounded corners that emphasize the versatile design of the speaker.

TWEETER WITH NEW FRONT PANEL

The Indiana Line Tesi 3 – like its predecessor – features a 26 mm tweeter with a special Indiana Line feature: a radial ventilation chamber and a powerful neodymium magnet. However, there is a noticeable change in the front design of the tweeter. The Tesi 3 model is rectangular in shape, reminiscent of the latest designs from Indiana Line’s flagship Diva series, but manufactured using a simplified mounting technique. This original approach ensures that the tweeter visually complements the midrange driver much more seamlessly, while also elevating the aesthetic qualities of the Tesi 3 model.

ENHANCED LOW/MID-FREQUENCIES SPEAKER

The midrange driver has been optimized using modern design techniques. It features a 16 cm diaphragm that is very robust, made of a mixture of mica and polypropylene. The main elements of the midrange driver are an inductance straightening ring and a larger magnet compared to the Tesi 261 model. In addition, the original phase plug in the Tesi 3 has been replaced with a dust cap in the new Tesi 3. These components contribute to the low distortion level and further increase the linearity and low-frequency processing - the bass frequencies are clear and deep. As a result, the sound is more detailed and clear, especially when playing at higher volumes.

DUAL-WAVE – AN INNOVATIVE SUSPENSION SYSTEM

The Tesi 3 model’s bass-midrange speaker features an innovative Dual-Wave suspension that debuts in Indiana Line’s higher-end Diva series models. The Dual-Wave suspension visually resembles the accordion-like springs found in stage speakers. Carefully designed to increase the linear operating range of the electro-acoustic transducer and reduce intermodulation distortion, with a particular focus on low frequencies, this suspension system has a significant impact on improving the clarity of sound in the mid-range of the acoustic spectrum. This is especially evident when listening to recordings with acoustic, string and percussion instruments.

IMPROVED SPEAKER CROSSOVER DESIGN

Tesi 3 boasts a carefully optimized speaker crossover, created using modern design technologies and specialized measurement systems. The crossover topology and the quality of its components are based on the solutions implemented in the Diva series models. As a result, a smooth impedance characteristic, high efficiency, low distortion levels and optimal off-axis sound dispersion were achieved. Thanks to these improvements, Tesi 3 works seamlessly with any amplifier or AV receiver.
