The Iridium GZIB 2.30BR ACT from Ground Zero has a power output of 250/400 watts, with 250 watts representing the RMS power and 400 watts the maximum power. These power parameters enable powerful and clear sound reproduction, which is particularly evident in high-energy audio applications. The integrated amplifier ensures that the power is available directly without external amplifier components. Especially if you like to listen to music loudly, the power ratings of this subwoofer provide a solid foundation. The combination of two 30 cm subwoofers and a bass reflex enclosure further enhances the sound.
The front bass reflex tunnel of the Iridium GZIB 2.30BR ACT significantly contributes to the improvement of bass reproduction by effectively projecting sound energy forward. This design allows the subwoofer to reproduce low frequencies with higher sound pressure, resulting in a deeper and more dynamic sound experience. The bass reflex tunnel is a central design feature that optimizes the resonance frequency of the enclosure, thereby enhancing the overall performance of the bass system. Especially in film or music applications where deep bass plays an important role, the tunnel shows its full advantages.
The housing of the Iridium GZIB 2.30BR ACT is made of wood, which gives the construction high stability and robustness. The bass reflex enclosure contains two 30 cm subwoofers and a permanently integrated amplifier. This stable design reduces vibrations and resonances that could potentially impair sound quality. Additionally, the surface is covered with an embroidered carpet, which not only provides an appealing look but also offers extra protection against damage. This combination of materials and design features ensures a long lifespan for the product.
The high-level input on the Iridium GZIB 2.30BR ACT simplifies installation by allowing the subwoofer to be connected directly to the speaker outputs of an existing audio system. This makes it easier to integrate into existing systems, especially when no preamp outputs are available. This connection option is particularly useful in vehicles that use only factory systems, as no additional high-to-low converter is required. Thus, the integration of the subwoofer is noticeably easier for individuals without extensive technical know-how.
The auto-on function of the Iridium GZIB 2.30BR ACT automatically activates the subwoofer as soon as an audio signal is detected. This means that the subwoofer wakes up from standby mode on its own, without the need for manual activation. This feature significantly enhances user convenience, as the subwoofer is always ready as soon as the audio system is turned on. This self-activation function prevents unnecessary energy consumption by putting the subwoofer into sleep mode when no audio signal is present. It is particularly useful for seamless integration into various audio applications.
The low-pass filter of the Iridium GZIB 2.30BR ACT ensures that only low-frequency signals are forwarded to the subwoofers. This means that high frequencies, which the subwoofer cannot reproduce optimally, are filtered out, improving overall sound quality and reducing distortion. This allows for clearer and more accurate bass reproduction, ideal for applications where deep bass-heavy audio content is in focus, such as music genres with pronounced bass or film soundtracks. The setting of the low-pass filter can be adjusted to optimally tailor the sound to specific needs.
The phase correction in the Iridium GZIB 2.30BR ACT is a technical feature that compensates for the influences of room acoustics by adjusting the phase of the signal to minimize disturbances. This is particularly important for correcting phase shifts between the subwoofers and the main speakers, thereby ensuring the synchronization of playback. Especially in complex audio systems with multiple speakers, phase correction helps to make the bass sound precise and powerful, optimizing the overall sound and ensuring a coherent soundstage.
The Iridium GZIB 2.30BR ACT fits into many vehicles due to its compact dimensions. However, the installation should be done with consideration of the specific space conditions, as the subwoofer contains two 30 cm drivers. Vehicles with generous trunk space or station wagons provide enough room to effectively mount the enclosure. During installation, it is important to leave space around the bass reflex tunnel to avoid impairing the bass performance. Those who are unsure should compare the dimensions with the available space in the car.
The carpet material of the Iridium GZIB 2.30BR ACT, adorned with embroidery, serves multiple functions. Firstly, it provides an elegant protection for the wooden housing against scratches and damage. Furthermore, the carpet material can help to dampen vibrations and oscillations, which has a positive impact on sound quality. This additional damping ensures that unwanted resonances are minimized to keep the bass reproduction as clear as possible. Additionally, the decorative design gives the subwoofer an aesthetically pleasing appearance.
The size of 30 cm per subwoofer in the Iridium GZIB 2.30BR ACT allows for deep bass reproduction that impresses in both home and vehicle audio applications. Larger subwoofers can move air more efficiently, resulting in a more intense and powerful bass presentation. A driver of this size is ideal for clearly reproducing frequencies in the lower range, which is particularly advantageous when playing music genres with strong bass. The enclosure works in conjunction with the subwoofers to maximize the overall sound experience.

Bass reflex cabinet with two 30 cm subwoofers and amplifier for deep bass

The bass-reflex enclosure of the Iridium GZIB 2.30BR ACT houses two 30 cm subwoofers, which, together with the integrated amplifier, produce impressive sound depth. The design with two 30 cm subwoofers enables wider frequency spectrum coverage and ensures powerful bass reproduction. Compared to smaller diameter subwoofers, the 30 cm subwoofers offer a larger cone surface area, enabling more efficient sound reproduction and deeper frequencies. This ensures that the bass is not only audible but also felt – ideal for use in car audio systems where powerful bass reproduction is crucial.

Front bass reflex tunnel to optimize bass performance

The Iridium GZIB 2.30BR ACT from Ground Zero utilizes a front ported bass reflex tunnel to further optimize bass reproduction. This design allows for more efficient control of airflow within the enclosure, resulting in clearer and more powerful bass. A well-designed ported bass tunnel can increase the sound pressure level at low frequencies without compromising overall sound quality. A larger or differently positioned ported bass tunnel could result in less precise or even boomy bass reproduction. The precise tuning of the ported design ensures that bass is heard clearly and distinctly both inside and outside the vehicle.
