Frequent questions about Iridium GZIB 30BR

Welche Leistung hat der Iridium GZIB 30BR Subwoofer?

The Iridium GZIB 30BR from Ground Zero has an RMS power handling of 350 watts at an impedance of 4 ohms. These power characteristics allow this enclosure subwoofer to produce deep and powerful bass frequencies. Thanks to the angled rear wall and an EFP front channel, the sound output and bass performance are further optimized. The device can thus deliver an undistorted sound image even at high volumes, ideal for music lovers who value detailed bass reproduction.

Welche Besonderheiten hat das Gehäuse des Iridium GZIB 30BR?

The Iridium GZIB 30BR subwoofer is housed in a passive bass reflex enclosure that includes a 30 cm IRIDIUM subwoofer. With a front bass reflex tunnel and a robust wooden housing, it ensures exceptionally precise and powerful bass reproduction. The wooden material helps minimize cabinet resonances, thereby improving sound quality. Additionally, the enclosure, with a net volume of 37 liters, provides optimal airflow for generating powerful bass. The angled rear wall supports systematic placement in the vehicle.

Wie ist der Iridium GZIB 30BR Subwoofer dimensioniert?

The Iridium GZIB 30BR has dimensions of 460 mm in width, 320 mm in height, and a depth of 327 mm at the top and 255 mm at the bottom. These dimensions allow for flexible integration into various vehicle models without significant loss of space in the trunk. The angled rear wall is particularly practical during installation, as it supports installation in sloped trunk areas. The precise design of the housing significantly enhances the sound performance of the subwoofer.

Welcher Subwoofer ist im Iridium GZIB 30BR integriert?

The subwoofer within the Iridium GZIB 30BR is the GZIW 30. This 30 cm subwoofer is known for its excellent sound capability and robustness. With an impedance of 4 Ohms and a power handling of 350 Watts, it offers remarkable sound power. The interplay with the passive bass reflex enclosure allows for the generation of deep, rich bass that fully captivates the music listener. In particular, the front bass reflex tunnel included in the enclosure improves the efficiency of the bass reflex opening, thereby further increasing the pressure and sound power.

Wie ist der Anschluss des Iridium GZIB 30BR gestaltet?

The Iridium GZIB 30BR is equipped with a clamp connection that allows for a secure and stable connection to the vehicle's audio system. Such a clamping mechanism not only ensures a smooth connection process but also provides a firm fit for the cables, minimizing sound losses. This type of connection also helps to minimize interference, as the cable routing is firmly fixed. This ensures reliable signal transmission, which is particularly important at strong bass frequencies to avoid distortion.

Wie wirkt sich das Netto Volumen des Iridium GZIB 30BR auf den Klang aus?

The net volume of the Iridium GZIB 30BR is 37 liters, which significantly contributes to sound quality. This carefully tuned cabinet volume allows for efficient airflow, which is essential for precise and effective bass reflex action. Such a cabinet construction is not only crucial for sound performance but also enhances the depth and clarity of low-frequency reproduction. Thus, the subwoofer delivers a powerful bass performance that complements even demanding music playback.

Welchen Einfluss hat der EFP Frontkanal auf die Bassleistung?

The EFP (Enhanced Function Port) front channel of the Iridium GZIB 30BR has a significant impact on bass performance by optimizing airflow within the enclosure. This front-mounted port reduces distortions that can arise from the bass reflex opening and increases the efficiency of sound delivery. This results in powerful and clear bass lines that remain intact even at high volumes. Especially in music genres with a pronounced bass component, the excellent performance of the EFP channel is evident, making the sound more powerful and providing a full, rich sound depth.

Gibt es Einschränkungen bei der Platzierung des Iridium GZIB 30BR?

Due to the angled rear wall of the enclosure, the Iridium GZIB 30BR offers flexible placement options, especially in vehicles with sloping trunk floors. The installation dimensions are: 460 mm width, 320 mm height, and 327/255 mm depth, which should fit most common car types. However, installation should be done in such a way that the bass reflex opening is not covered, in order to avoid impairing acoustic performance. Additionally, it is important to ensure that the subwoofer is securely installed to provide stability while driving.

Welche Materialien wurden für das Gehäuse des Iridium GZIB 30BR verwendet?

The housing of the Iridium GZIB 30BR is made of high-quality wood, which is crucial for the robustness and stability of the subwoofer. Wood is an excellent material for reducing cabinet resonances that could negatively affect sound reproduction. The use of sturdy wooden structures ensures that the structural integrity is maintained even at high volume levels, while also allowing for a more natural-sounding bass reproduction. Additionally, the wooden construction contributes to the durability of the housing, even under demanding conditions and vibrations in the car.

Wie unterstützt der Front Bassreflex-Tunnel des Iridium GZIB 30BR den Bassklang?

The front bass reflex tunnel of the Iridium GZIB 30BR is responsible for the efficient discharge of air currents generated by the subwoofer. This helps to produce powerful deep bass with minimal distortion. The tunnel acts as a channel that releases air pressure in front of the enclosure while reducing excessive vibrations that could affect the sound. This design allows the subwoofer to provide significantly increased output performance, which is particularly evident in electronic music or cinema-like projections that benefit from deep bass.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
