The Velodyne Story . . .

Founded in 1983 by David Hall,

Velodyne Acoustics is the result of an

effort to bring the discipline of me-

chanical engineering and the doctrine of common sense to the field of high performance audio- the Silicon Valley approach to sound.

Through innovative thinking and inventive design, the company pio- neered the first true servo-controlled subwoofers. The result was both the reference standard for bass repro- duction and the foundation for distor- tion-free listening.

Rejecting the trend toward high-end indulgence or fancy marketing gim- micks with no relevance to improving sound, Velodyne devoted its techni- cal resources to bringing the benefits of ultra-low distortion technology within the reach of all dedicated music lovers. In fact, many state of the art recording studios & homes now feature Velodyne subwoofers as their "reference standard" by which all others should be judged.

With the introduction of Velodyne's Distortion Free Series for the automo- bile, listeners finally have access to all the details and dynamics that make up the modern listening experi- ence. Anything imperfect originates elsewhere. By design, Velodyne speakers are incapable of error.

to the amplifier. Forcing the speaker's acoustical output into a true representation of the music.

The term "servo" is misused by some manufacturers who use a different motor on their speakers to try and make woofers sound like larger more powerful units. Unfortunately this usually results in a large amount of distortion as well. At Velodyne, we take an already large & powerful speaker, then use motional feedback to create a true "servo" controlled speaker. This reduces distorion and achieves a level of sound quality never before heard of.

DF-10sc, DF-12sc specifications

Velodyne Acoustics is renowned for its innovation in audio technology, and the DF-12sc and DF-10sc are shining examples of this legacy. Designed for audiophiles and sound enthusiasts, these subwoofers deliver exceptional sound quality and incorporate advanced features to elevate the listening experience.

The DF-12sc boasts a powerful 12-inch driver, while the DF-10sc is equipped with a slightly smaller 10-inch driver. Both models utilize Velodyne's proprietary Digital Drive Technology, which allows for precise control over the subwoofer's performance. This technology ensures that the bass reproduction is not only deep and impactful but also clear and distortion-free at all volume levels. This level of clarity is vital for accurately reproducing the complex low-frequency components of music and film soundtracks.

One of the standout features of both models is their sophisticated room equalization technology. The Smart EQ feature helps to analyze the listening environment and automatically adjusts the subwoofer's output accordingly. This ensures optimal performance regardless of the space, leading to precise bass reproduction that adapts to the acoustics of the room.

The user-friendly interface on both subwoofers makes setup a breeze. With intuitive controls and a convenient remote, users can easily adjust volume levels, phase, and crossover settings. This flexibility allows for fine-tuning to match personal preferences and system requirements, making it suitable for various applications, from home theaters to music playback setups.

The DF-12sc and DF-10sc subwoofers are constructed with premium materials, ensuring durability and minimal resonance. Their robust cabinets are designed to eliminate unwanted vibrations, allowing for a clean bass output. They also feature high-quality finishes that can blend seamlessly into any home décor.

In terms of connectivity, both models include multiple input options, including line-level and speaker-level connections, making them compatible with a wide range of AV receivers and audio setups. This versatility further enhances their appeal, as users can integrate them easily into existing systems.

In summary, the Velodyne Acoustics DF-12sc and DF-10sc subwoofers stand out for their powerful performance, advanced technologies, and thoughtful design. Whether for a dedicated home theater or a high-fidelity music system, these subwoofers deliver an exceptional auditory experience that meets the demands of even the most discerning listeners.
