Nota 740 X

The Indiana Line Nota 740 X 2-way central speaker uses a symmetrical arrangement of electroacoustic transducers and a back ported bass reflex cabinet. Two 107 mm woofers, which warmly reproduce the sound of the midrange and a tweeter with a diameter of 26 mm are responsible for the sound. The wholeness is guaranteed by a wide frequency response. The Indiana Line Nota 740 X model is a confirmation of the Italian design craftsmanship. It has been created primarily for use in home theater systems, in operation with other loudspeakers from the Indiana Line Nota series.

Indiana Line Nota 740 X

Indiana Line is one of the most important Italian brands in the audio sector. It offers loudspeakers as well as installation speakers. Its traditions date back to 1977. The designers and engineers working for Indiana Line aim to develop models characterized by the highest quality workmanship with rationally used components. Thanks to this, the sound qualities that go far beyond the parameters achieved by competing models available in a similar price range have been achieved.

Italian style craftsmanship

The Nota series is characterized by a timeless design that perfectly confirms the craftsmanship of Italian style and design thought. Properly profiled side panels give the speakers that belong to it a characteristic look. In combination with a durable and aesthetic vinyl coating, which is available in light walnut or black oak, the Nota 740 X will not only decorate the interior of your listening room but will also amaze you with its dynamic and emotional sound. In combination with other, appropriately selected components, you will be able to feel almost like during a “live” concert.

Nota 740 X – perfect for home theater systems

The Indiana Line Nota 740 X is a 2-way center speaker with a 26 mm dome tweeter and a pair of 107 mm mid-woofers. They work in a horizontal symmetrical arrangement in which the tweeter is located between two woofers. The bass reflex port is located at the back, which reduces the audibility of resonances coming from the inside, having a negative impact on the clarity of the played voice. Nota 740 X has been created primarily for use in home theater systems. It will work especially well in medium-sized rooms (from approx. 12 to approx. 20 m2). Together with the Nota 550 X floorstanding speakers or the Nota 260 X bookshelf speakers (as front speakers) and the Nota 240 X models (as effect speakers), you can create a complete, sonically-coherent set of speakers prepared for sound handling, among others, in DTS: X standard. The Nota 740 X loudspeaker has an amplifier loading impedance between 4 – 8 ohms, and the power of the amplifier should be from 30 and 100 W.

Clear and pure sound

Polypropylene membranes of symmetrically placed mid-woofers smoothly and warmly reflect the sound of the midrange, and at the same time guarantee a solid dose of bass. As in the woofers used in other models from the Nota series, also here the mid-woofers have micro-grooves similar to a CD. The tweeter with a neodymium magnet and radial rear chamber is located in a specially profiled front, which improves the dispersion of treble. Moreover, the Nota 740 X model in the tweeter filter only has air coils and foil capacitors, which makes the treble extremely clear and distinct.

100% polyester damping

All Indiana Line cabinets are filled with polyester – a synthetic non-woven fabric of high purity, known for its excellent damping of the internal resonances of the speaker cabinets. What's more, polyester is also extremely resistant to stretching, drying and moisture.

Air coils and film capacitors

In order to emphasize the exceptionally clear and natural sound of our loudspeakers, we decided to get rid of the troublesome components from the crossover where it was necessary – in the tweeter filter. In all loudspeaker models in which this filter is used, we use only air coils and foil capacitors. These elements do not introduce harmful distortions to the filtered signal, as is the case with ferrite core coils and electrolytic capacitors.

MDF housing with transverse reinforcements

Indiana Line loudspeakers cabinets are made of MDF panels. They are made using the latest production techniques, which ensures high precision of workmanship, great repeatability and excellent performance parameters for many years. MDF is a moisture-resistant material, it is massive and it suppresses all resonances very well. To completely remove unwanted vibrations, we used transverse reinforcements of the cabinet. They take the form of horizontal rings that are located at key points along the entire height of the loudspeaker cabinet.

MDF housing with transverse reinforcements


A radial damping chamber that prevents harmful reflections under the tweeter dome while allowing it to achieve a low resonance frequency. The small, but at the same time strong magnet of the tweeter is surrounded by a space in which – due to its shape – standing waves cannot be generated, which is the case with classic radial chambers located in the axis of the dome.
