Indiana Line

Indiana Line, founded in Turin in 1977, has built a reputation on a clear philosophy: offering high-fidelity sound with excellent value for money. Their design approach focuses on creating well-engineered, sonically optimized speakers without unnecessary frills, resulting in products that deliver a great listening experience. Their three main series—Nota, Tesi, and Diva—each cater to different levels of performance and aesthetics.

Here's a more detailed look at the brand and its key product lines:

Core Design Philosophy and Technology

Indiana Line speakers are characterised by several shared technical and design features that contribute to their sound quality:

Solid Cabinet Construction: Most models feature cabinets made from dense MDF (Medium-Density Fiberboard), often with internal bracing to reduce unwanted resonances and vibrations. This ensures a clean, undistorted sound.

High-Quality Drivers: The brand uses carefully selected drivers, often with proprietary technologies. Many woofers and mid-woofers feature mica-reinforced polypropylene cones, which provide a balance of stiffness and damping for precise and dynamic sound reproduction.

Dual-Wave Suspension: A notable innovation, particularly in the Tesi and Diva series, is the Dual-Wave suspension for woofers. This technology, inspired by professional stage speakers, extends the linear range of the driver's movement and reduces intermodulation distortion, resulting in clearer midrange and more articulate bass.

Radial Venting Chamber: The brand's 26mm silk dome tweeters often incorporate a radial venting chamber. This feature helps to control the dispersion of high frequencies, ensuring a smooth and detailed treble response without harshness.

Optimised Crossovers: Indiana Line designs its crossover filters to work seamlessly with their drivers, which allows them to use simpler, more direct filter designs. This helps maintain a regular impedance curve, making the speakers an easy load for a wide range of amplifiers.

Nota Series

The Nota series represents Indiana Line's entry-level, but highly regarded, line of speakers. They are known for their exceptional value, offering a sound quality that punches well above their price point.

Target Audience: Newcomers to hi-fi, those with smaller budgets, or anyone looking for a great-sounding, no-nonsense speaker for a stereo or home cinema system.

Sound Profile: The Nota series is often described as having a warm, musical, and engaging sound. The bass is surprisingly deep and powerful for the size, and the treble is smooth and non-fatiguing. They are designed to be forgiving of less-than-perfect recordings and entry-level electronics.

Key Models: The series includes bookshelf models like the Nota 260 X and Nota 240 X, a center speaker, and the floorstanding Nota 550 X.

Tesi Series

The Tesi series sits in the middle of Indiana Line's portfolio. It builds upon the Nota series by incorporating more advanced technologies and higher-quality components, offering a more refined sound and aesthetic.

Target Audience: Audiophiles and music lovers seeking a more detailed and sophisticated listening experience without moving into the high-end price bracket. The Tesi series is a great choice for both dedicated stereo systems and more advanced home theaters.

Sound Profile: The Tesi speakers deliver a more balanced and detailed sound compared to the Nota series. The use of technologies like the Dual-Wave suspension and upgraded crossover components results in clearer vocals, more precise instrument separation, and a wider, more convincing soundstage. The bass is tighter and more controlled.

Key Models: This series features a full lineup including bookshelf models like the Tesi 3, floorstanding speakers such as the Tesi 6 and Tesi 5, a center speaker, and a subwoofer.

UTAH Series

The UTAH series is a new addition to the Indiana Line family, drawing inspiration from the brand's heritage with a distinct retro design. It combines this classic aesthetic with modern acoustic engineering.

Target Audience: Music lovers who appreciate a vintage, throwback style and a dynamic sound profile. They are well-suited for a variety of music genres, from classic rock to electronic music.

Sound Profile: The UTAH speakers are known for their dynamic, vibrant, and spacious sound. They feature a large woofer and a "twin-port" bass-reflex system that fires downward, creating powerful, rhythmic, and deep bass. The sound is designed to be warm and engaging, with smooth highs.

Key Models: The series is currently centered around the UTAH 5 floorstanding speaker. This model is a 3-way design with a 10-inch woofer and a unique cabinet that is slightly tilted to improve sound alignment when placed directly on the floor.

Diva Series

The Diva series represents Indiana Line's flagship line of loudspeakers. They are the pinnacle of the brand's design and engineering, combining premium aesthetics with top-tier sound performance.

Target Audience: Discerning audiophiles who demand the highest level of performance from Indiana Line, a sophisticated design, and a full-bodied sound signature.

Sound Profile: The Diva series is known for its exceptional fidelity, neutrality, and resolution. The speakers feature meticulously optimized drivers, including mid-woofers with Curv composite cones. This results in incredibly precise bass, a natural and transparent midrange, and airy, extended highs.

Key Models: The series includes the bookshelf Diva 3, the 2.5-way floorstander Diva 5, and the three-way floorstander Diva 6.

Dedicated Subwoofers

BASSO Series

The BASSO series is a dedicated line of active subwoofers designed to complement any of the Indiana Line speaker series. They are not part of a specific "speaker" range but rather a separate category of products.Purpose: To extend the low-frequency response of a stereo or home cinema system, providing deep, powerful, and controlled bass.

Key Models: The main models are the Basso 840 and Basso 880. Both feature a downward-firing woofer to use the floor as a bass reinforcement. The Basso 840 uses a Class AB amplifier, while the more powerful Basso 880 uses a Class D amplifier for higher power and efficiency. They both offer a full suite of controls (crossover frequency, gain, and phase switch) to seamlessly integrate with any main speakers.
