Frequent questions about Competition GZCM 6.5XSPL

Wie hoch ist die Belastbarkeit des Competition GZCM 6.5XSPL Lautsprechers?

The Competition GZCM 6.5XSPL speaker from Ground Zero offers an impressive power handling of 120 Watts RMS and can handle peaks of up to 320 Watts. These performance characteristics make the speaker particularly suitable for applications where high volume and clarity are required. Especially in dynamic and powerful midrange passages, this speaker showcases its strengths. The construction of fiber-reinforced paper diaphragm and a robust ferrite magnet ensures excellent power transmission and reliability even under demanding conditions.

Welche technischen Merkmale besitzt der Ground Zero Competition GZCM 6.5XSPL Lautsprecher?

The Ground Zero Competition GZCM 6.5XSPL is a 165 mm high-power midrange speaker, equipped with a 30 mm CCA voice coil and a fiber-reinforced paper diaphragm. A resonance-optimized steel basket and the ferrite magnet contribute to the sound performance. The water resistance and UV resistance of the paper diaphragm ensure high durability. This combination of materials and design makes it ideal for versatile applications, especially for car sound systems that require both durability and excellent sound quality.

Welche Abmessungen hat der Ground Zero Competition GZCM 6.5XSPL Lautsprecher?

With a diameter of 165 mm and a mounting diameter of 143 mm, the Ground Zero Competition GZCM 6.5XSPL speaker is compactly designed. The installation depth is 74 mm, allowing for easy integration into a variety of speaker enclosures or vehicle doors. These dimensions ensure that the speaker fits into standard mounting openings, while the high-quality materials and robust construction guarantee easy installation and exceptional sound quality. Pay attention to the depth during installation to avoid affecting the sound.

Was ist der Wirkungsgrad des Competition GZCM 6.5XSPL Lautsprechers?

The efficiency of the Ground Zero Competition GZCM 6.5XSPL speaker is 95 dB, indicating a very efficient conversion of electrical energy into acoustic energy. A high efficiency means that the speaker can produce a large volume with relatively low power input. This is particularly important for applications where energy savings and volume are a priority, without compromising sound quality. An efficiency of 95 dB provides an impressive sound presence, especially in vehicle installations.

Welche Frequenzbereiche kann der Competition GZCM 6.5XSPL abdecken?

The Ground Zero Competition GZCM 6.5XSPL is capable of covering frequencies from 150 Hz to 11 kHz. This encompasses a large part of the midrange, which is crucial for the clarity and detail accuracy of music playback. Such a wide frequency response ensures that all relevant sonic details are reproduced, especially in setup configurations where the midrange is particularly stressed. The resonance frequency is at 86 Hz, which makes the speaker ideally suited for the precise reproduction of voices and instruments.

Welche Materialien werden in der Konstruktion des Ground Zero Competition GZCM 6.5XSPL verwendet?

In the Ground Zero Competition GZCM 6.5XSPL speaker, high-quality materials are used to ensure both sound quality and durability. The fiber-reinforced paper diaphragm offers an optimal compromise between stiffness and damping. The resonance-free steel basket reduces unwanted vibration noise, while the ferrite magnet maximizes the magnetic field strength to ensure precise sound reproduction. The water-repellent and UV-resistant surface of the diaphragm protects against environmental influences. This combination of materials makes the speaker particularly suitable for demanding applications.

Wie beeinflusst die 30 mm CCA Schwingspule die Leistung des Lautsprechers?

The 30 mm CCA (Copper Coated Aluminum) voice coil in the Ground Zero Competition GZCM 6.5XSPL ensures excellent thermal and electrical conductivity. Aluminum is lighter than copper, which increases the mobility of the voice coil, while the copper coating reduces resistance and thus increases efficiency. This combination allows for high load capacity and excellent response speed. The voice coil plays a crucial role in the precision and clarity of sound reproduction, especially at high volumes, without the risk of distortion or overheating.

Gibt es Tipps zur Platzierung des Competition GZCM 6.5XSPL Lautsprechers im Fahrzeug?

For the optimal placement of the Ground Zero Competition GZCM 6.5XSPL in the vehicle, attention should be paid to the installation diameter of 143 mm and the installation depth of 74 mm to ensure that the speaker is mounted correctly. An installation in the door panels is ideal, as this positioning ensures both good sound distribution and minimal influence from vibrations. Proper sealing and fastening significantly contribute to sound quality. Additionally, all electrical connections should be properly insulated to avoid short circuits.

Welche Vorteile bietet die wasserabweisende Papiermembran des Competition GZCM 6.5XSPL?

The water-repellent paper membrane of the Ground Zero Competition GZCM 6.5XSPL offers significant advantages in humid or challenging environments. This feature ensures that the speaker is protected against splashes, which is particularly important for use in vehicles or outdoor applications. The UV resistance of the membrane also increases durability, as it is protected from harmful sunlight. Thus, sound quality is maintained over longer periods, and the speaker remains effective even under difficult conditions.

Mit welchen Fahrzeugtypen ist der Ground Zero Competition GZCM 6.5XSPL kompatibel?

The Ground Zero Competition GZCM 6.5XSPL is fundamentally compatible with many types of vehicles, especially those that offer space for 165 mm speakers. The dimensions of the speaker – a mounting diameter of 143 mm and a mounting depth of 74 mm – fit into most standardized mounting devices in vehicles. It is important to check the existing mounting openings in the vehicle to ensure that the speaker can be properly installed. Adjustments may be necessary if the mounting parameters do not perfectly match the vehicle conditions.

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!
