SUBWOOFER LOW-PASS

VOLUMECROSSOVER

80 Hz

When installed in this fashion, your satellite speakers will be crossed over at 80Hz which removes the lower bass from your amplifier and speakers, enabling them to do a better job reproducing high frequencies. By utilizing this method, you will have a bi-amplified system, gaining improved power and headroom for your system.

Subwoofer outputs

The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover. Some processors/receivers, have a "subwoofer out" jack that is internally filtered and designed to be used with a conventional amplifier and speaker. In some rare cases, combining both an external crossover and the one internal to the subwoofer may result in low output and increased noise. In these installations you may need to bypass the internal crossover in either the processor or Velodyne subwoofer. In some installations, simply setting one crossover to a higher frequency (such as 120 Hz) will restore maximum performance. To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal from another crossover, simply locate the switch marked X-over, OUT - IN on the rear panel of the subwoofer and set to the OUT position.

If not using an external crossover, you should use the built-in crossover for optimal performance.

Interconnect cables

––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––

When installing your new Velodyne subwoofer using the line level connections, you should always use shielded phono cables. There are many decent cables available today, most any of which will work perfectly well. We do recommend that you keep the length of cable as short as possible to avoid any potential noise problems.

When routing cables, try to keep them away from equipment which generates significant noise such as industrial or digital equipment.

HGS 12, HGS 10 specifications

Velodyne Acoustics is a company renowned for its innovation in the audio technology field, particularly in subwoofer design. Two of its standout products are the HGS-10 and HGS-12 subwoofers. These models embody Velodyne’s commitment to delivering powerful, high-fidelity sound by combining advanced technologies with user-friendly features.

The HGS-10 and HGS-12 subwoofers are designed to provide deep bass extension and superior control, making them ideal for both home theater and music listening environments. One of their main features is their use of Velodyne’s patented Digital Drive Technology. This technology utilizes advanced digital signal processing to monitor and control the movement of the subwoofer driver in real-time, ensuring that the sound quality remains consistent and distortion-free, even at high volume levels.

Both models house large, powerful drivers that are engineered for maximum efficiency. The HGS-10 includes a 10-inch driver, while the HGS-12 features a larger 12-inch driver, allowing for deeper bass response. The cabinet design of these subwoofers is also notable; they are constructed with a sturdy, well-braced enclosure that minimizes unwanted vibrations, enhancing sound clarity.

The subwoofers are equipped with a variety of connectivity options, including line-level inputs and outputs, enabling easy integration into existing audio systems. They also feature adjustable crossover controls, allowing users to tailor the frequency response to match their listening environment. This flexibility makes it possible to achieve optimal performance regardless of the room’s acoustics.

Another significant characteristic of the HGS series is the inclusion of the room control feature. This allows users to optimize bass response based on their specific room characteristics, enhancing overall audio performance. Additionally, both models come with a remote control, enabling users to make adjustments from the comfort of their seating area.

In summary, Velodyne Acoustics HGS-10 and HGS-12 subwoofers stand out for their combination of advanced technologies, powerful drivers, and user-centric features. With their ability to deliver exceptional bass performance while minimizing distortion, they cater to audiophiles and home theater enthusiasts alike, solidifying Velodyne’s presence in the high-performance audio market. These subwoofers are more than just typical audio equipment; they are a testament to the pursuit of audio excellence.
