Indiana Line Tesi 3
Representing the latest iteration of the Tesi series, the Tesi 3 bookshelf model not only presents itself exceptionally well but also delivers an attractive, balanced, clear, and dynamic sound – unparalleled in its price class. The new Tesi line models boast innovative technical solutions, incorporating components proven in the latest flagship Diva series models while maintaining a simple and versatile design. The Tesi 3 model is available in three colour variants – black oak, white, and mocha, allowing it to seamlessly integrate into the decor of any interior.
Reinforced enclosure, universal style
The Tesi 3 model features an internally reinforced MDF enclosure. In comparison to the Tesi 261 model, the dimensions have slightly changed – it is approximately 2 cm shorter and has a depth of 1 cm smaller. The front-facing bass reflex port facilitates easy placement in a room while ensuring dynamic low tones. The mid-woofer driver basket has a trim ring, contributing to the speaker’s aesthetic appeal. Additionally, the Tesi 3 model has a magnetic grille, and like other models in the new generation Tesi series, it boasts gently rounded corners, highlighting the speaker’s universal design.
Tweeter with a new front panel
The Indiana Line Tesi 3 – much like its predecessor – features a 26-millimeter high-frequency transducer with the Indiana Line’s special feature: a Radial Venting Chamber and a powerful neodymium magnet. However, there is a notable change in the front design of the tweeter. The Tesi 3 model adopts a rectangular shape, reminiscent of the latest designs from Indiana Line’s flagship Diva series but crafted using a simplified mounting technique. This original approach ensures that the tweeter visually complements the midwoofer much more seamlessly, simultaneously elevating the aesthetic qualities of the Tesi 3 model.
Improved midwoofer
The midwoofer has been optimized using modern design techniques. It boasts a 16 cm membrane with high rigidity, crafted from mica-polypropylene blend. Key elements of the midwoofer include the inductance linearization ring and a larger magnet compared to the Tesi 261 model. Moreover, the original phase plug has been replaced in the Tesi 3 with a dust cap in the new Tesi 3. These components contribute to a low level of distortion and further enhance linearity and the processing of low frequencies – the bass is distinct and deep. This results in greater detail and clarity in the sound, especially when playing audio at higher volumes.
Dual-Wave – innovative suspension system
The low-midrange speaker in the Tesi 3 model features the innovative Dual-Wave suspension, making its debut in higher-tier models of Indiana Line’s Diva series. The Dual-Wave suspension visually resembles the accordion-like springs found in stage speakers. Carefully designed to enhance the linear operating range of the electroacoustic transducer and reduce intermodulation distortion, with a particular focus on low frequencies, this suspension system has a significant impact on improving sound clarity in the midrange of the acoustic spectrum. This is particularly evident when listening to recordings featuring acoustic, string, and percussion instruments.
Improved speaker crossover design
Tesi 3 boasts a carefully optimized speaker crossover designed using modern design techniques and specialized measurement systems. The crossover’s topology and the quality of its components are based on solutions implemented in models from the Diva series. As a result, a smooth impedance characteristic, high efficiency, low distortion levels, and optimal off-axis sound dispersion have been achieved. Thanks to these advancements, the Tesi 3 seamlessly collaborates with any amplifier or AV receiver.
