The HECO Aurora 900 AM is a floorstanding speaker that incorporates a Dolby Atmos speaker for an immersive and uncomplicated cinema sound. It is part of the Aurora series, which features innovative technology and elegant design. The Aurora 900 AM is ideal for movie and series fans who want to experience a new dimension of sound without compromise and hassle.
The Aurora 900 AM features a three-way bass reflex design for the main speaker, which means it has three separate drivers for low, mid, and high frequencies, and a ported enclosure that enhances the bass response. The drivers are carefully selected and optimized to work together harmoniously and deliver a balanced and coherent sound across the frequency spectrum.
The low frequencies are handled by two 170 mm woofers, which have kraft paper cones that are light, stiff, and fast. Kraft paper is a traditional material that has been used by HECO for decades, and it is known for its natural and warm sound. The woofers can reproduce deep and punchy bass with minimal distortion and compression.
The midrange frequencies are reproduced by a 170 mm driver, which also has a kraft paper cone. The midrange driver is responsible for the most important part of the sound, where the human voice and most musical instruments are located. The midrange driver ensures a clear and detailed sound with a smooth and realistic tonality.
The high frequencies are reproduced by a 28 mm fabric dome tweeter, which is part of the Fluktus system developed by HECO. The Fluktus tweeter has a corrugated flange that surrounds the dome and acts as a waveguide, improving the dispersion and reducing the diffraction of the sound waves. The fabric dome is soft and flexible, which results in a smooth and silky sound with a high level of resolution and transparency.
The Aurora 900 AM also features an integrated coaxial speaker for Dolby Atmos, which is mounted on the top of the cabinet and fires upwards. The coaxial speaker has a 100 mm woofer and a 20 mm tweeter, which are designed and certified according to Dolby Atmos guidelines. The coaxial speaker uses the ceiling to create a perfect spatial impression that matches the audio mix of the movie or series. The coaxial speaker has its own connecting terminal, which allows for easy cabling and setup.
The drivers are mounted on a sturdy and multi-braced cabinet, which is made of MDF and has a thickness of 25 mm. The cabinet has an L-shaped resin baffle that covers the front and top of the speaker, adding rigidity and reducing resonance. The cabinet is available in two color options: ebony black or ivory white, both with a silk matte lacquer finish. The cabinet is also equipped with crossbeams and height-adjustable metal cone spikes, which provide stability and isolation from the floor.
The Aurora 900 AM has a high sensitivity of 91 dB for the main speaker and 88 dB for the top speaker, which means it can produce a loud sound with a relatively low power input. The speaker has a nominal impedance of 4 ohms, which is not difficult to drive for most amplifiers. The speaker has a frequency response of 25 - 42,500 Hz for the main speaker and 50 - 35,000 Hz for the top speaker, which covers the entire audible range and beyond. The speaker has a crossover frequency of 8,500 Hz for the top speaker and 260 and 3,300 Hz for the main speaker, which is the point where the sound is divided between the drivers.
The Aurora 900 AM has a pair of gold-plated binding posts at the back of the cabinet for the main speaker, which allow for bi-wiring or bi-amping. Bi-wiring means using two separate cables to connect the speaker to the amplifier, one for the low and mid frequencies and one for the high frequencies. Bi-amping means using two separate amplifiers to power the speaker, one for the low and mid frequencies and one for the high frequencies. Both methods can improve the sound quality by reducing the interference and increasing the headroom. The speaker also has a separate pair of gold-plated binding posts for the top speaker, which can be connected to a Dolby Atmos compatible receiver or amplifier.
The Aurora 900 AM is a speaker that offers a lot of value for its price. It is a speaker that can deliver a rich and full sound with a wide dynamic range and a broad and even dispersion. It is a speaker that can handle any type of content with ease and grace. It is a speaker that can create a lifelike and immersive soundstage that will make you feel like you are in the middle of the action. It is a speaker that will make you fall in love with your movies and series all over again.
