System Design Suggestions

The Velodyne product you have purchased was designed to offer you the greatest amount of flexibility possible in your vehicle's sound system. However, due to the nature of the servo-control circuitry, there are some suggestions you should observe to avoid any problems and ensure maximum performance. Please read and observe these requirements before proceeding with system instal- lation.

When choosing an amplifier, it must have extended low frequency response down to at least 10 hz

Optimum performance is typically realized with one dedi- cated amplifier per woofer

Amplifier used must have gain adjustment

Amplifier used should be capable of supplying woofer with a minimum of 100 watts RMS

Maximum suggested amplifier power is 300 watts RMS

When installed in a sealed enclosure, the unit may require an amplifier towards the high end of the scale (200-300w); when used in an infinite baffle setup, power requirements are reduced and satisfactory performance may be attained with a smaller amp (100-200w)

Sealed enclosures: accurate sound, simple to build but require more amp power than other enclosures

Infinite baffle: accurate sound, simple installation, lowest power requirements

Ported enclosures: much higher output, low power require- ments but more complex to build

As you can see from this diagram, the speaker and amplifier now become part of a loop. Actual cone motion is monitored, so now we can control the drive signal to the amplifier. In essence, controlling how the speaker responds.

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.
