d&b audiotechnik V-GSUB Cardioid Subwoofer

The d&b audiotechnik V-GSUB is a high-performance cardioid subwoofer designed for professional sound reinforcement applications where controlled low-frequency coverage and powerful bass reproduction are required. Part of the d&b V-Series, the V-GSUB combines an 18-inch front-facing driver with a 12-inch rear-facing driver to create its cardioid dispersion pattern.

The V-GSUB is specifically intended for ground-stacked applications. Unlike the closely related V-SUB, the V-GSUB does not incorporate the V-SUB’s integrated flying rigging system. Instead, the V-GSUB is designed as a ground-stack subwoofer and incorporates features that help maintain cabinet stability when used with compatible V-Series loudspeakers.

This d&b audiotechnik V-GSUB is offered in excellent condition and is suitable for professional rental companies, touring productions, concert systems, festivals, venues, production companies and sound reinforcement professionals.

d&b audiotechnik V-GSUB Cardioid Subwoofer

The d&b audiotechnik V-GSUB is an actively driven high-performance cardioid subwoofer powered by a single amplifier channel. Its dual-driver arrangement is central to its cardioid operating principle.

The V-GSUB incorporates one 18-inch long-excursion neodymium driver in a bass-reflex design facing toward the front of the cabinet and one 12-inch long-excursion neodymium driver in a two-chamber bandpass design facing toward the rear.

This front-and-rear driver arrangement produces the cardioid dispersion characteristic for which the V-GSUB is designed. d&b explains that this arrangement reduces unwanted low-frequency energy behind the system and helps reduce excitation of the reverberant field.

For professional sound systems, controlled low-frequency radiation can be particularly important when the subwoofer system is positioned close to the stage, audience or other reflective surfaces.

High-Performance Cardioid Design

One of the defining features of the d&b V-GSUB is its cardioid behavior.

Traditional subwoofers radiate low-frequency energy over a relatively broad area. Cardioid subwoofer designs are intended to provide greater control over where that low-frequency energy is directed.

The V-GSUB achieves this through its combination of front- and rear-facing drivers and carefully designed acoustic chambers.

The result is a high-performance subwoofer capable of producing powerful low-frequency output while providing controlled radiation toward the rear of the cabinet.

For touring sound systems and ground-stacked PA configurations, this characteristic can be useful when engineers need to manage low-frequency energy on stage or behind the main PA system.

18-Inch and 12-Inch Drivers

The d&b audiotechnik V-GSUB uses two long-excursion neodymium drivers.

The front of the enclosure houses a single 18-inch driver in a bass-reflex configuration.

The rear section houses a 12-inch driver within a two-chamber bandpass design.

This combination is responsible for the V-GSUB’s low-frequency performance and cardioid behavior. d&b lists the system’s nominal impedance as 8 Ω and power handling capacity as 800 W RMS / 3,200 W peak for 10 ms.

The carefully engineered driver configuration allows the V-GSUB to provide substantial low-frequency output while maintaining the controlled directivity expected from a professional cardioid subwoofer.

Frequency Response

The d&b V-GSUB provides a frequency response of 37 Hz to 115 Hz at -5 dB in its standard mode.

In 100 Hz mode, the specified frequency response is 37 Hz to 95 Hz.

This frequency range makes the V-GSUB suitable for reinforcing the low-frequency portion of professional PA systems.

It can be deployed with compatible V-Series loudspeakers where additional low-frequency extension and output are required.

The 37 Hz lower frequency specification allows the V-GSUB to reproduce substantial low-frequency content while maintaining the controlled operating range expected from a dedicated professional subwoofer.

Maximum Sound Pressure Level

When operated with compatible d&b amplifiers, the V-GSUB is specified at up to 137 dB maximum sound pressure level under the manufacturer’s stated measurement conditions.

d&b specifies this maximum SPL figure with D40, D80, D90 and 40D amplifier configurations on its current product documentation, with the specific amplifier configuration affecting the stated conditions.

The manufacturer defines the measurement at 1 metre in free field using a peak SPL measurement and a pink-noise test signal with a crest factor of 4.

For professional system design, the manufacturer’s amplifier and processing recommendations should always be followed rather than treating maximum SPL as a standalone indicator of complete system performance.

d&b Amplifier Compatibility

The d&b audiotechnik V-GSUB is designed to operate with d&b amplification and processing.

d&b’s current product documentation lists the D40 and D80 as mobile amplifiers for the V-GSUB and the 40D for installation applications. The manufacturer also provides information about compatible heritage amplifier configurations through current amplifier firmware release notes.

The V-GSUB is specified for two cabinets per amplifier channel with the current compatible amplifier configurations listed by d&b.

This integrated d&b system approach provides amplification, loudspeaker processing and protection functions specifically designed around the loudspeaker system.

Ground-Stacked Application

A major distinction between the V-GSUB and the V-SUB is the intended deployment method.

The V-GSUB is designed for ground-stacked applications only. d&b describes the V-GSUB as sharing the same acoustical and visual design as the V-SUB while omitting the V-SUB’s integrated flying rigging equipment.

The top of the V-GSUB includes a recessed area corresponding to the footprint of a V7P or V10P enclosure. This allows a compatible V-Series top loudspeaker to be positioned securely on the subwoofer.

The cabinet also includes runners on the bottom and corresponding recesses on the top surface, helping prevent cabinet movement when multiple V-GSUB units are stacked.

This makes the V-GSUB particularly useful for ground-stacked V-Series configurations.

V-GSUB with V7P and V10P

The d&b V-GSUB can be used as part of ground-stacked systems incorporating compatible V-Series loudspeakers.

The top panel’s recessed footprint is specifically shaped to accept a V7P or V10P enclosure, helping provide a stable stack configuration.

For productions using V7P or V10P loudspeakers, the V-GSUB can therefore provide the low-frequency foundation of a ground-stacked V-Series system.

The precise system configuration, amplifier setup and processing should always follow the applicable d&b system documentation.

Professional Touring Applications

The d&b audiotechnik V-GSUB is suitable for a variety of professional sound reinforcement applications.

Typical applications include:

* Concert touring
* Festival sound systems
* Live music
* Outdoor events
* Corporate productions
* Professional rental systems
* Theatre productions
* Large event production
* Ground-stacked PA systems
* V-Series sound systems
* Professional fixed sound reinforcement

Its cardioid low-frequency design makes it particularly relevant where controlled bass radiation is important.

The relatively compact enclosure also allows professional production companies to transport and deploy multiple V-GSUB units as part of larger sound systems.

Cardioid Low-Frequency Control

The d&b V-GSUB is designed around controlled low-frequency reproduction.

Its cardioid configuration helps reduce unwanted energy radiating toward the rear of the subwoofer system.

This can be beneficial in professional live sound applications where excessive low-frequency energy behind the PA can affect the stage environment or contribute to unwanted excitation of the surrounding acoustic space.

The V-GSUB’s front 18-inch driver and rear 12-inch driver work together as part of the system’s cardioid acoustic design.

This approach provides a more controlled low-frequency pattern than a conventional single-direction subwoofer configuration.
