Indiana Line Diva 752
Indiana Line is one of the most important Italian brands on the audio market offering loudspeakers and installation speakers. Its traditions date back to 1977. The goal of Indiana Line engineers and designers has always been to launch on the market models characterized by high quality workmanship. Properly selected components allow manufacturing loudspeakers with sonic qualities that go far beyond the technical parameters that can be achieved in this price range.
The loudspeakers like an Italian diva
Diva series is the flagship series in the Indiana Line brand’s offer and the pride of its main designer. It stands out among the other product lines in the Italian brand with its finish. A beautiful black piano lacquer has been used here. The loudspeakers belonging to this line are like a real Italian diva, who hides a hot southern temperament inside – when she appears on stage, the whispers stop, and a spectacle of excellent sound that delights the crowds begins.
A perfect model for home theater systems
The Indiana Line Diva 752 is a 2-way central speaker with a pair of 140 mm mid-woofers and a 26 mm tweeter placed between them. It can be placed near a wall to enhance low frequencies thanks to the bass reflex cabinet with a rear-firing port. The low tuning of the bass reflex system ensures great bass extension combined with a great impulse response. Importantly, the set also includes a bass reflex port bung, which allows you to reduce the influence of this element on the sound of the loudspeaker. This speaker, intended for the center channel, is a natural complement to a high-quality home theater system created with the use of other loudspeakers from the Diva Indiana Line series. The Diva 752 model will sound best with an amplifier with a power from 30 to 100 W. The amplifier loading impedance of this loudspeaker is 4 – 8 ohms.
A well-designed construction
The central column of Diva 752 uses the latest revision of the tweeter with silk, a 26-millimeter dome. The tweeter is embedded in the cabinet with a soft, rubber pad, isolating it from the potential vibrations of the speaker cabinet. This driver is equipped with a radial rear chamber with two types of damping materials and propelled by a strong neodymium magnet. The tweeter is placed symmetrically between two woofers with unique Curv cones, made of woven polypropylene. The mid-woofer profile provides excellent directional characteristics and optimal internal damping in a wide frequency range. Cast aluminum, acoustically transparent baskets of electro-acoustic drivers confirm the high-class construction and guarantee no noticeable coloration of the acoustic spectrum in the midrange. What’s more, the magnetic drives of the woofers have aluminum impedance linearizing rings, which reduces the THD (Total Harmonic Distortion), and also improves the thermal working conditions of the coils.
Proper bandwidth distribution
A carefully tuned crossover with air coils (instead of ferrite core coils, which can make undesirable distortions) ensures the correct distribution of the processed frequency band (from 35 Hz to 22 kHz). Additionally, the filter section responsible for the tweeter is based solely on foil capacitors. What is important, the speaker terminals used in this model have been made of magnetically inert materials and allow the speaker to be connected in bi-wiring or bi-amping.
Rich sound and a wide soundstage
The technical solutions used in the Diva 752 model contributed to the dynamic and clear sound, even at high audio volume levels. Indiana Line designers and engineers’ attention to detail and the high quality of all components allowed the Italian Diva to go to the heights of sound quality. The sophisticated geometry of the drivers and the materials used for the membranes resulted in a clear, yet strong midrange. Also noteworthy is the detailed and open sound of the treble. They are complemented by a deep and warm bass that does not dominate, but at the same time marks its presence. The sound stage is wide and extremely engaging for the listener.
