Frequent questions about Competition GZCF 6.5XSPL

Wie sind die Abmessungen des Competition GZCF 6.5XSPL?

The Competition GZCF 6.5XSPL from Ground Zero has a diameter of 165 mm, which corresponds to the standard for 6.5-inch models in the speaker industry. The cut-out diameter is 145 mm, and the mounting depth is 70 mm. These dimensions are crucial when considering installation in various vehicle types. Proper sizing ensures a correct fit and affects acoustic performance. Make sure that the vehicle's speaker grilles provide enough space to install the speakers without physical constraints. The included hexagon protective grille can be helpful in ensuring optimal protection.

Welche Materialien verwendet der Competition GZCF 6.5XSPL für die Membran?

The Competition GZCF 6.5XSPL uses a pressed paper cone in combination with a long-stroke foam W-surround. The choice of paper cone provides natural sound reproduction and minimizes distortion that could be released by resonance. The specially designed foam W-surround improves the cone's excursion behavior, keeping the speaker stable even at high volumes. This combination of materials is crucial for the sound quality and high performance of this coaxial speaker. Another advantage is the UV resistance and water repellency, ensuring durability and resistance to environmental influences.

Was sind die Besonderheiten der Schwingspule im Competition GZCF 6.5XSPL?

The Competition GZCF 6.5XSPL is equipped with a 38 mm copper-coated aluminum flat wire voice coil. The material and design of this voice coil are central to the efficiency and sound development of the speaker. Copper-coated aluminum offers an excellent mix of weight and conductivity, ideal for dynamic and precise sound reproduction. The flat wire allows for better winding density in the coil system, meaning that more wire can be accommodated in the given volume, which utilizes the magnetic force more efficiently and leads to higher performance and better thermal load capacity.

Welche Frequenzen deckt der Competition GZCF 6.5XSPL ab?

The competition-GZCF-6.5XSPL offers a frequency response of 50 Hz to 20 kHz. This bandwidth covers the most important frequencies of human hearing and allows the speaker to effectively reproduce both deep bass and high frequencies. Such a frequency range is particularly useful when you want to listen to music styles with large tonal ranges, as it enables the speaker to accurately represent different sound elements. In combination with the 12 dB/octave crossover, a clear separation between high and low frequencies is ensured, creating a smooth sound curve.

Welche Rolle spielt der Ferritmagnet im Design des Competition GZCF 6.5XSPL?

The Competition GZCF 6.5XSPL uses a ferrite magnet to generate the magnetic field for the voice coil. Ferrite is a common choice due to its cost and performance efficiency compared to cobalt or neodymium magnets. The magnet provides a constant magnetic force, which stabilizes the acoustic performance of the speaker. It is important in the design to ensure that the speaker operates dynamically and without loss. Especially if you like to listen to music loudly, the magnet provides the necessary drive for clear and precise reproduction across the entire frequency range and at high volumes.

Wie ist der Wirkungsgrad des Competition GZCF 6.5XSPL zu beurteilen?

The Ground Zero Competition GZCF 6.5XSPL has a high efficiency of 94 dB, making it a suitable choice for users who want to get the maximum sound volume out of their audio environment. A higher efficiency means that the speaker can produce more sound power from the electrical energy supplied to it. This is particularly advantageous in cars, where space is limited and installing larger speakers is not an option. When choosing a speaker, high efficiency is crucial for maximum performance, especially in environments where energy efficiency plays a role.

Wie beeinflusst der resonanzarme Stahlkorb die Leistung des GZCF 6.5XSPL?

The resonance-optimized steel basket of the Competition GZCF 6.5XSPL minimizes unwanted vibrations that can distort sound in speaker systems. A stable basket is crucial for the structural integrity of the speaker, as it securely holds the moving parts of the speaker in place. By utilizing a resonance-optimized material like steel, it ensures that no additional vibrational energies are generated that could cause distortion or coloration of sound. This means natural sound reproduction while maintaining precision and detail, which is why this aspect is an essential part of speaker design.

Wie trägt der 28 mm PEI Hochtöner zur Klangleistung des Competition GZCF 6.5XSPL bei?

The 28 mm PEI tweeter of the Competition GZCF 6.5XSPL is specialized in reproducing high frequencies and significantly contributes to the balance of the overall sound image. PEI (Polyetherimide) is a thermoplastic material that offers both durability and sound transparency. Therefore, the tweeter can reproduce high frequencies without distortion even under intense use, which is particularly advantageous for complex musical pieces with many highs. Through compatibility with the rest of the speaker system, listeners achieve a nuanced and detailed reproduction that meets the demands of different music genres.

Welche Bedeutung hat die 12 dB/Oktave Frequenzweiche beim Competition GZCF 6.5XSPL?

The 12 dB/octave crossover in the Competition GZCF 6.5XSPL ensures efficient separation of highs and lows and allows for precise sound tuning between the tweeter and woofer. This type of crossover provides a relatively steep transition between the speaker components, resulting in minimal overlap. The clear structuring ensures that each frequency is accurately directed to the appropriate speaker to minimize distortion. In a speaker system, the crossover is crucial for maintaining dynamics and clarity as well as maximizing listening enjoyment.

Ist der Competition GZCF 6.5XSPL UV-resistent und wasserabweisend?

The Ground Zero Competition GZCF 6.5XSPL is both UV-resistant and water-repellent. These properties make the speaker particularly suitable for various environments such as outdoor applications or humid interiors, where conventional speakers might suffer damage. With protection against harmful UV rays and moisture, the speaker is durable and maintains its sound and performance quality over long periods. The UV resistance protects against discoloration and material fatigue, while the water-repellent feature ensures that no moisture can penetrate the speaker system and impair its function.

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!
