This technology is complemented by the Hexatech™ aluminum voice coil, which ensures improved heat dissipation due to its large diameter. The combination of Hybrid™ neodymium/ferrite magnets and Uniflow™ chassis minimizes air restrictions and achieves a high load capacity of up to 1,000 watts. These technical features make the EW 638 an excellent choice for demanding sound installations that do not want to compromise on sound quality.

Wie hoch ist die Belastbarkeit des EW 638?

The maximum load capacity of the EW 638 speaker from Morel is an impressive 1,000 watts, making it ideal for high-performance audio systems. This mid-bass driver also offers a continuous power handling (QMW) of 150 watts, making it a versatile component for various audio applications. The high load capacity is achieved through the use of the Hexatech™ aluminum voice coil, which ensures excellent heat dissipation. Thus, the EW 638 is well-equipped to reproduce both low and mid frequencies across a wide spectrum.

Welche Frequenzen kann der Morel EW 638 abdecken?

The Morel EW 638 covers a wide frequency spectrum from 40 to 4,000 Hz, making it suitable for both low and mid frequencies. This is supported by the innovative DPC membrane, which optimizes sound reproduction across the entire spectrum. The mechanical and electrical quality (Qms 1.71 and Qes 0.39) as well as the total quality factor (Qts 0.32) maximize the efficiency of the speaker. These parameters make the EW 638 an excellent choice for anyone seeking comprehensive sound performance in their audio systems.

Wie ist der Morel EW 638 konstruiert?

The Morel EW 638 is a 6.5" (16.5 cm) midrange driver based on a Uniflow™ aluminum chassis, which effectively reduces air restrictions. Its outer diameter is 160.02 mm, while the cutout diameter measures 140 mm, and the overall depth is 69.08 mm. The speaker uses a Hexatech™ aluminum voice coil with a diameter of 76.2 mm and an innovative Hybrid™ neodymium/ferrite magnet. This ensures precise sound reproduction and robustness of the speaker unit. This construction supports the speaker in delivering clear and powerful sounds.

Was sind die Thiele-Small-Parameter des EW 638?

The Thiele-Small parameters of the Morel EW 638 help to better understand the performance characteristics and application areas of the speaker. The DC resistance (Re) is 5 ohms, while the voice coil inductance (Le) is 0.52 mH. The resonance frequency (Fs) of the speaker is 39 Hz. The mechanical quality factor (Qms) is 1.71, the electrical quality factor (Qes) is 0.39, and the total quality factor (Qts) is 0.32. These parameters are crucial for fine-tuning the speaker in a cabinet and for integration into an existing sound system.

Warum hat der Morel EW 638 eine Aluminium-Schwingspule?

The Morel EW 638 uses a Hexatech™ aluminum voice coil to maximize thermal efficiency and improve sound quality. Aluminum is an ideal material for voice coils as it has both good conductivity and low weight. This combination allows for a faster response to electrical signals, resulting in clear and precise audio reproduction. The large coil size of 76.2 mm also enhances durability and provides a clean sound image, even under higher power demands.

Wie beeinflusst der Uniflow™-Chassis die Klangqualität des EW 638?

The Uniflow™ chassis of the Morel EW 638 midrange driver plays a crucial role in sound quality by minimizing air restrictions that can cause sound distortions. The special design of the chassis optimizes air circulation around the speaker unit, resulting in a cooler operating environment and lower distortion at high volumes. This promotes a clear, powerful sound, further enhanced by the combined use of the Hybrid™ neodymium/ferrite magnet and the DPC membrane, making it ideal for professional audio applications.

Was ist die Membranfläche des Morel EW 638?

The membrane area of the Morel EW 638 is 119 cm². This area is crucial for the efficiency with which the speaker can produce sound waves and directly affects the sound quality and bass reproduction. A larger membrane area allows the speaker to move more air, resulting in a more powerful and fuller soundstage. The choice of poly-composite material contributes to the lightness and stiffness of the membrane, ensuring that the sound remains clear and free of excessive resonance.

Wie installiere ich den Morel EW 638 in mein Fahrzeug?

The installation of the Morel EW 638 in a vehicle requires precision, as the speaker has certain dimensions. With an outer diameter of 160.02 mm and a cutout diameter of 140 mm, it fits many standardized installation openings. Make sure to consider the overall depth of 69.08 mm to avoid space issues. The mounting holes have a diameter of 4.2 mm, allowing the speaker to be securely mounted. It is important to carefully choose the installation position to ensure optimal performance of the speaker.

Welche Empfindlichkeit hat der Morel EW 638 Lautsprecher?

The Morel EW 638 has a sensitivity of 87 dB (SPL at 1m / 2.83V), indicating how effectively the speaker can produce sound. This sensitivity ensures that the speaker sounds good even with moderate amplifier power. In practical applications, this means that the EW 638 is capable of delivering an impressive sound fullness with relative output power.

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 .

X-10 v3 d2

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!
