Immerse yourself in the sonic world of the new Indiana Line TESI range. These speakers represent the culmination of years of acoustic research and offer a new listening experience, both for passionate audiophiles and beginners looking for their first quality HiFi system. Discover how this range redefines performance standards in its price category.
The evolution of the TESI range
The new generation of TESI Indiana Line speakers brings significant technical improvements. This is a significant update to this iconic line, aimed at delivering a better sound experience.
The changes affect every key aspect of the speakers: new, more complex and rigid cabinets, revised transducers, and higher-quality crossovers. Each element has been optimized to create a cohesive whole that enhances the listening experience.
TESI 2 bookshelf speakers
The youngest in the range, the TESI 2, delivers impressive performance despite its compact size. Equipped with a 120 mm midrange/bass driver, it delivers an impressive soundstage in both width and depth. Its front-facing bass-reflex port allows for flexible installation, even close to a wall.
TESI 3 bookshelf speakers
A natural evolution of the TESI 2, the TESI 3 incorporates a more generous 160 mm midrange/bass driver, giving it significantly better bass response. The soundstage gains in breadth and substance, with a particularly expressive midrange that constitutes the strong point of this speaker.
The TESI 5 floorstanding speakers
The first floorstanding speaker in this new range, the TESI 5 features a 3-way configuration with a 160mm midrange driver and an identical bass driver. Its extended bandwidth (38-22000 Hz) allows it to faithfully reproduce a wide range of musical works.
The TESI 6 floorstanding speakers
The flagship of the range, the TESI 6 offers a 3-way configuration with a 160 mm midrange driver and two bass drivers of the same size. Its unique feature lies in its bass-reflex vent that opens under the speaker, which rests on a cross-shaped base that lifts it off the floor. This ingenious design allows for 360° dispersion of low frequencies, ensuring even distribution of the extreme bass throughout the room.
Technology at the service of musical emotion
What truly sets the Indiana Line TESI apart is its ability to transform technical innovations into pure musical emotion. Every design choice was guided not only by objective acoustic considerations, but also by the emotional impact it produces when listening. Let’s take a closer look at the exclusive technologies that make these speakers instruments capable of touching the soul of music lovers.
- Sophisticated cabinetmaking
The ultra-rigid MDF cabinetry with strategic transverse reinforcements eliminates any coloration due to cabinet vibrations. This neutrality allows for faithful reproduction of instrumental and vocal timbres, preserving the original artistic intent.
- Silk Dome Tweeter
The 26mm silk dome tweeter is a deliberate choice for musicality over drama. Its radial damping chamber and powerful neodymium magnet allow it to reproduce the most delicate harmonics with a smoothness and precision that invites you to rediscover your music collection.
- Suspension Dual Wave
The exclusive Dual Wave suspension of the midrange and bass drivers is a major innovation. It significantly extends the linear operating range of the transducers and minimizes intermodulation distortion, particularly in the low frequencies, resulting in a more natural and engaging reproduction of bass instruments.
- Sophisticated Filtering
The filtering, using air-wound coils and polypropylene capacitors, is directly inspired by the manufacturer’s high-end models. This uncompromising approach ensures a seamless transition between the different transducers and preserves the full coherence and richness of the recordings.
Choosing the TESI model that suits your needs
| Model | Type | Grave speakers | Medium speakers | Tweeter | Bandwidth | surface area |
| TESI 2 | Bookshelf | 1 x 120 mm | Same as the grave | 26 mm silk | 45 Hz – 22 kHz | < 20 m² |
| TESI 3 | Bookshelf | 1 x 160 mm | Same as the grave | 26 mm silk | 42 Hz – 22 kHz | < 25 m² |
| TESI 5 | Floorstand | 1 x 160 mm | 1 x 160 mm | 26 mm silk | 38 Hz – 22 kHz | < 35 m² |
| TESI 6 | Floorstand | 2 x 160 mm | 1 x 160 mm | 26 mm silk | 35 Hz – 22 kHz | > 25 m² |
Beyond the technical specifications, the choice between these different models also depends on your listening preferences. If you prioritize precision and fine details, the TESI 2 and TESI 3 bookshelf models might appeal to you with their ability to create a precise stereo image. If, on the other hand, you’re looking for a more immersive experience with a physical bass impact, the TESI 5 and TESI 6 loorstanding models will perfectly meet your expectations.
It’s also important to consider how the speakers will fit into your living space. Bookshelf models offer great flexibility in placement (on stands, a shelf, or even mounted on the wall), while floorstanders create a more assertive presence but require dedicated floor space.
Recommended associations and system optimization
To get the most out of your Indiana Line TESI speakers, it’s essential to pair them with quality complementary components. A HiFi system is like an orchestra, where each element must play in perfect harmony with the others. Here are our recommendations for creating a cohesive system that will enhance the qualities of your speakers.

Beyond the choice of components, optimizing your setup plays a crucial role in the final listening quality. Here are some practical tips to help you get the most out of your TESI speakers.
How to place your TESI speakers?
The positioning of the speakers in your listening room significantly influences the sound quality. For bookshelf models, choose dedicated stands rather than shelves to avoid unwanted resonances. The ideal height places the tweeter approximately at ear level in the listening position.
Maintain a minimum distance from the rear wall (15 cm for bookshelves, 25-30 cm for columns) to avoid artificial bass boost. The spacing between speakers determines the width of the soundstage; start with a distance equivalent to the distance from the listening point, then adjust according to your preferences.
Don’t neglect the toe-in angle (orientation toward the listening point), which can radically transform the sound image. A slight angle (5 to 15 degrees) generally offers the best compromise between central image precision and soundstage width.
An essential reference in its category
The new Indiana Line TESI represents a true feat in the world of affordable hi-fi. Rarely have speakers at this price point offered such a combination of technical and musical qualities. Whether it’s the compact TESI 2, the versatile TESI 3, the elegant TESI 5 floorstanding speakers, or the impressive TESI 6, each model in the range delivers performance that far exceeds legitimate expectations at its price point.
What truly sets TESI speakers apart is their ability to reconcile objective qualities (neutrality, precision, definition) with the musical emotion that constitutes the very essence of the listening experience. Too often, affordable speakers sacrifice one for the other, becoming either clinically precise but soulless, or warm but imprecise. TESI remarkably manages to avoid both pitfalls, delivering faithful reproduction that preserves all the emotion of the recordings.
For passionate audiophiles, the TESIs represent an exceptional opportunity to access sound quality usually reserved for much more expensive speakers. Their transparency and neutrality allow you to rediscover your music collection in a new light, revealing details and nuances previously unnoticed.
For beginners in the world of high-fidelity, they are an ideal gateway to quality listening. Their immediately appealing musicality and their tolerance towards the associated electronics make them easy-to-live-with partners, which will evolve harmoniously with the rest of the system over the course of future improvements.
Ultimately, the Indiana Line TESI speakers perfectly embody what modern hi-fi should be: accessible musical instruments, without unnecessary pretension, but designed with rigor and passion to offer an authentic listening experience. They remind us that acoustic excellence is not necessarily synonymous with prohibitive prices, but that it is above all the result of intelligent design and proven know-how. An essential reference that fully deserves its place at the heart of your Hi-Fi system, whether you are a discerning audiophile or a budding music lover.
