Ascendo Speakers

Mr. Norbert Heinz, Mr. Stefan Kopf and Mr. Jurgen Scheuring founded ASCENDO in Stuttgart Germany in 1999. For over two decades, ASCENDO has been manufacturing high-end speakers that deliver the best surround sound audio that many audio enthusiasts admire. ASCENDO high-end speakers can reproduce the smallest detail in audio, and they are handcrafted using the best components and materials with the utmost precision by optimally trained specialists in Germany. Music connoisseurs all over the world love the perfection of ASCENDO´s speaker masterpieces. With just the same scrupulousness and uncompromising commitment to the very best, ASCENDO IMMERSIVE AUDIO manufactures its home theater speakers.

If you want to design the ultimate dedicated Home Theatre with surround sound decoding of Dolby Atmos, Auro-3D, and DTS:X Pro, which gives better performance than an actual cinema hall and does not restrict budget, then ASCENDO should be your first choice.

Normally, in a high-end dedicated home theater system, all speakers connected to power amplifiers via long wires suffer from some kind of power loss and reduced performance. Add-on passive crossovers inside the speakers also lose some power.

Powered speakers overcome these issues by integrating optimized amplifiers directly within the speaker. A digital crossover splits the audio signal into divided frequencies, which are sent to amplifiers connected by short, high-quality cables to every speaker. This setup reduces power loss, improves control, and increases frequency response. Also, advanced protection circuitry ensures the lifespan and performance of each driver and amplifier channel. Powered speakers provide superior performance and efficiency compared to passive designs.

The AIA speaker management software enables centralized control, management, and monitoring of complex audio installations. With AIA Creator speaker management software, all powered speakers, subwoofers, and external amplifier modules connect into a unified system, managing both master and group functions and millions of individual parameters in real time. This system supports configurations from single speakers to extensive immersive home theaters and networked audio over IP systems.

Each speaker includes powerful internal audio processing and multiple preset memory functions for room correction and speaker alignment. Key features include level and gain adjustment, delay time, matrix routing, bass management, and speaker group voicing with different user access levels. Standard settings like X-curve calibrations and specific loudness curves can also be stored. Additionally, AVB streams can be split to enhance surround channels with different time alignments, switch between formats like Dolby Atmos, DTSX Pro, or Auro-3D, and easily adjust setups for various listening positions.

Coaxial speaker designs provide a single-point source and ensure a consistent acoustic center and balanced dispersion pattern. This accompanies homogeneous sound reproduction with perfect transient response and high intelligibility. Conventional non-coaxial multi-way speakers experience inconsistent sound due to varying distances between the listener and speaker, and audible crossover points. These issues are noticeable in theater with more comprehensive listener arrays.

Coaxial speaker design, with drivers on a similar axis, solves these issues. It offers a balanced response on both vertical and horizontal axes at every angle, ensuring excellent crossover transitions and mirrored behavior about the axis. Non-coaxial speaker design cannot achieve this equilibrium.

The ASCENDO infrasonic subwoofers are the greatest advancement for luxury high-end home theaters. They deliver precise and powerful infrasonic low frequencies, creating an immersive experience with deep bass that is felt as well as heard.

Infrasonic bass is key for high-performance, in delicate home theaters, pressuring the room and enhancing the physical impact intended by many Hollywood action movies and Bollywood soundtracks. True infrasonic subwoofers are extremely hard to engineer and work in tandem with other subwoofers in the home theater to do their part, extending bass into the single Hz digits. Proper calibration of timing, phase, and level with all home theater channels ensures that ASCENDO infrasonic subwoofers provide an unforgettable, fully immersive audio experience.

The ASCENDO The15 Be PRO PASSIVE ON WALL  is an extremely impressive and extraordinary performing custom home speaker for Movies and Music. This 15″ point source axisymmetric speaker has been designed as a behind-screen speaker for large delicate home theaters. Front left, center, and Front right speakers can also be used as surround speakers. ASCENDO’s passive crossover technology, paired with the highest grade flat wound OFC copper air core coils and silver capacitors, works in combination with the enclosure and coaxial driver design to deliver ultra-precise and swift impulse response. The 15 Be PRO PASSIVE is capable of incredible SPL levels, but also the more impressive dynamic contrasts from whispering dialogues to explosive effects, which reproduces every possible dynamic range with ease. Even the most complex film passages with extreme dynamic requirements are reproduced at the highest clarity and lowest distortion.

Beryllium is one of the most expensive materials used to make ASCENDO The15 PRO PASSIVE ON WALL speaker diaphragms; in terms of stiffness-to-weight ratio, Beryllium is the highest of any known metal and can deliver dramatically superior results when adequately incorporated into a speaker design.  The speed of sound through Beryllium is nearly 2.5 times faster than the speed of sound through aluminum or titanium. This means the first breakup will occur at a much higher frequency, well outside the audible range. Breakup occurs when the cone partially vibrates at specific audible frequencies and, therefore, isn’t entirely piston throughout its range. This leads to non-linearities in the amplitude response as well as stored energy in the time domain.
