Indiana Line Dive 5

Indiana Line The brand was founded in 1977. Over the years of its existence on the market, it has firmly established itself as one of the most important Italian brands in the audio industry. The Indiana Line product range consists mainly of loudspeakers and built-in speakers. Indiana Line designers consistently strive to combine the highest quality production with the rational use of components. The result is models that in many ways surpass speakers in a similar price category.

DIVA - Top Series in a new version

Among all Indiana Line models, the Diva series speakers hold a special place. This flagship product line perfectly combines elegant design with solid craftsmanship and excellent sound quality. The new Diva series models feature mechanically and acoustically stable speaker housings "lockers" and stylish finish. The front part of the housing is painted with matte varnish (white or black, depending on the color variant), and the rest of the housing is covered with PVC shell.

Two color options are available: black body with black front or oak body with white front.

A stylish cabinet with a guide front

The Diva 5 speaker has a two-piece cabinet made of MDF. One of the parts is a 30 mm thick front panel, which increases the mechanical stability of the cabinet and prevents unwanted resonance, significantly improving the clarity of the sound. The front part is slightly tilted back, with a lower bottom and a deeper top, giving the speaker a noble appearance, as it rests on sturdy aluminum legs. The attractive design of the Diva 5 is highlighted by a magnetically attached, acoustically transparent grille, which replaces the previously used plastic pins for attaching the cover, as seen in other speakers in the Diva series.

Improved electro -acoustic converters

The Diva 5 model has undergone several changes compared to the previous Diva series speakers. Notably, the speaker baskets have been redesigned with more streamlined edges, reducing air resistance behind the diaphragm and reducing unwanted resonance. These baskets have been specifically designed to work seamlessly with the Dual-Wave suspension, ensuring proper function and exceptional aesthetics.

Sophisticated Curv membranes

The 2.5-way Diva 5 speaker has a woofer and a midrange driver with a Curv (polypropylene composite) membranes. This choice of woofer materials ensures a more neutral and precise bass response. These specific membranes are manufactured exclusively by Indiana Line on a special order basis.

PC optimize parameters

The magnetic systems of the woofer and midrange have been optimized using Finite Element Analysis (FEA) to improve their performance across a wide range of amplitudes and frequencies. The magnetic cores of each transducer are highly saturated, which reduces coil inductance and distortion, including intermodulation distortion. In addition, the inductance is linear, as in many previous Indiana Line models, using an Aluring demodulation ring. This element has been used for both the low-midrange and woofer transducers, resulting in clearer and more expressive sound even at high volumes, regardless of the genre of music being played.

Original protection design

A unique feature introduced for the first time in the Indiana Line speakers is the Dual-Wave surround sound found in the Diva 5 model’s woofer and midrange drivers. This precisely engineered top suspension extends the speaker’s linear operating range, reducing distortion, especially in the low-frequency registers, and improving midrange articulation. This has a positive effect, especially on the sound of percussion, string and acoustic instruments. The Dual-Wave solution also reduces frequency response irregularities due to diaphragm edge resonance, without the need for additional varnishing. The visually appealing design of the Dual-Wave transducers is reminiscent of professional stereo equipment with the so-called accordion suspension.

Another new feature of the Indiana Line speakers compared to current speakers on the market is the tweeter design. It features a unique radial damping chamber in the form of a ring surrounding the voice coil, as opposed to the conventional volume behind the dome. This design ensures a natural high-frequency sound and helps to avoid the unwanted resonance often associated with conventional designs. The front plate of the Diva 5 tweeter has also been significantly modified, being cast from aluminum and featuring an optimally shaped rubber surface. These changes help to expand the sound space and fill the room with high frequencies more effectively.

Computer -optimized crossover

The crossover used in the Diva 5 model has been redesigned and optimized using computer simulations. The circuit topology, number of components and their parameters have been precisely matched to the speaker cabinet and transducers, resulting in a balanced frequency range, low distortion, reduced power loss and sound quality that has been confirmed by extensive listening tests. The specially designed crossover circuit allows the Diva 5 to work smoothly with almost any amplifier.

Air coil and foil capacitors

The tweeter filter system uses only air coils and foil capacitors, eliminating the potential distortion often associated with electrolytic capacitors or ferrite core coils. Where core coils are used in the crossover, they have a laminated high-silicon iron core to reduce iron core distortion.
