Indiana Line TESI 7, 2-way center speaker

The Tesi 7 center column is a 2-lane, belonging to the new generation Indiana Line Tesi series. It is inspired by the Tesi 761 model, but has many improvements compared to its predecessor. These improvements improved the dynamics of sound reproduction and eliminated unwanted distortions and resonances. Unlike the Tesi 761, the tweeter in the Tesi 7 column is symmetrically positioned between the two mid-range speakers.

• Recommended amplifier power: 30 - 140 W
• Frequency range: 45 - 22000 Hz
• Sensitivity (2.8 V/1 m): 93 dB
• Amplifier load resistance: 4-8 ohms
• 2-lane

INDIANA LINE TESI 7

It not only presents itself perfectly, but also provides an attractive, balanced, clean and dynamic sound. It maintains a simple and versatile shape, in line with other columns in the new generation Tesi series. This model includes innovative technical solutions and components previously proven in the top Indiana Line Diva series. Tesi 7 is available in three color options - black oak, white and mocha. This allows users to create a sound system perfectly tailored to their audio needs and room decor.

UNIVERSAL DESIGN

The Tesi 7 model has been optimized for realistic and accurate reproduction, especially for movie dialogues or narrator voices. The internally reinforced body is made of MDF, and the low-mid drivers have trim rings that mask the baskets, giving the column an ​​aesthetic look. The dimensions of the Tesi 7 remain unchanged compared to the original. Similarly, a bass reflex port – like the Tesi 761 – is located at the back, allowing you to boost the low tones by placing the speaker closer to a wall or, if necessary, placing it in a niche in a cabinet or shelf. Like the other speakers in the new generation Tesi series, the Tesi 7 has subtly rounded upper housing edges and a magnetically attached grille to emphasize its versatile style.

NEW TREBLE FRONT PLATE

The Indiana Line Tesi 7, like the Tesi 761 speaker, has a 26 mm tweeter with a unique radial damping chamber and a powerful neodymium magnet. However, unlike the original, the Tesi 7 tweeter has a rectangular front instead of a circular one, again drawing inspiration from the flagship Diva series. However, the front part is made using simplified mounting methods. The result is similar - the front of the tweeter visually matches the symmetrically positioned low-midrange drivers on either side.

IMPROVED LOW-MIDRANGE CONVERTERS

The midrange speakers used in the Tesi 7 model have been optimized using modern design techniques. Each has a 16cm diameter rigid polypropylene membrane mixed with mica and an aluminum ring linear inductance. Compared to the Tesi 761 model, the magnetic systems of the converters have been increased, the phase correctors have been replaced with dust caps. The components and solutions used ensure high efficiency while maintaining a low level of distortion. Compared to the original, the bass processing has been optimized, resulting in a more dynamic bass for engaging sound effects and a clear foundation for human voices.

DUAL-WAVE SUSPENSION

The mid-range speakers used in the Tesi 7 center speaker have Dual-Wave suspension, an innovative solution first introduced in the Diva series models. This innovative approach is inspired by stage speakers with accordion-like springs. Dual-Wave increases the linear operating range of the converter and reduces intermodulation distortion, especially in the low frequency range. This improvement also increases the clarity of the mid-range of the acoustic spectrum, which is especially desirable for a center speaker in a home theater system handling dialogue or narrator voices in movies.

WELL DESIGNED CROSSOVER

The Indiana Line Tesi 7 center speaker crossover has been optimized using the latest design techniques and specialized measurement systems. The same topology and similar quality of components as in the crossovers of the flagship models of the Diva series have been preserved. The crossover ensures smooth impedance characteristics, high efficiency, low distortion levels and optimal off-axis sound dispersion. These features make the Tesi 7 seamlessly compatible with any home theater receiver.
