The frequency response, starting at a resonance frequency (Fs) of 28 Hz, underscores the subwoofer's ability to reproduce very deep bass accurately and without distortion.

Welche Abmessungen hat der GTI124 Subwoofer von Crunch?

The Crunch GTI124 is a 12-inch (30 cm) subwoofer that is particularly versatile due to its compact installation depth of 9.9 cm. This flat design allows for easy installation in various vehicles, even when space is limited. The diameter and installation depth are essential measurements that are crucial for ensuring an optimal fit and performance during installation. The specific construction with the flat steel basket also supports the stability and durability of the subwoofer in daily use.

Wie einfach ist die Installation des Crunch GTI124?

The installation of the Crunch GTI124 is very user-friendly thanks to the practical screw terminals. These allow for a quick and secure connection without complicated wiring. The flat design with a mounting depth of 9.9 cm makes installation easier even in vehicles with limited space. The robust aluminum membrane and the flat steel basket additionally contribute to stability during installation. For best performance, the subwoofer should be installed in a housing that is tuned to the parameters Vas of 58.5 liters and Qts of 0.68 to optimize sound quality.

Wofür eignet sich die 50 mm Schwingspule des GTI124 besonders?

The 50 mm voice coil of the Crunch GTI124 is a key element that ensures the production of powerful and deep bass tones. This larger voice coil improves heat dissipation and allows for greater load capacity, resulting in higher continuous power. This is particularly advantageous when listening to music with intense bass, as the speakers are less likely to overheat quickly and can thus be operated at high volume for longer periods. Additionally, the voice coil supports the excellent X-Max of +/- 18 mm, allowing for greater diaphragm excursion for even deeper bass reproduction.

Inwiefern beeinflussen die Thiele Small Parameter den Klang des GTI124?

The Thiele Small parameters are crucial for predicting the sound behavior of a subwoofer. For the Crunch GTI124, these are the Vas of 58.5 liters, the Qts of 0.68, and the frequency of 28 Hz. These parameters demonstrate that the GTI124 works particularly effectively in smaller enclosure volumes and accurately reproduces deep bass due to its low resonance frequency. The Qts value of 0.68 indicates a good balance between control and bass fullness, ideal for those seeking a mix of precise bass reproduction and powerful output.

Welche Unterschiede bietet die Konstruktion des Flachstahlkorbs beim Crunch GTI124?

The flat steel basket in the Crunch GTI124 is characterized by its exceptional stability and durability. This design minimizes unwanted vibrations and ensures consistent sound reproduction throughout the subwoofer's lifespan. Compared to conventional materials, the flat steel basket provides better support for the aluminum diaphragm, which can help reduce distortion and produce a clearer sound. Especially when you use the subwoofer under demanding conditions, this construction advantage can significantly impact overall performance and sound quality.

Welche maximalen X-Max Werte erreicht der GTI124 Subwoofer und was bedeuten sie?

The GTI124 from Crunch achieves an impressive X-Max of +/- 18 mm. This specification describes the maximum linear displacement of the diaphragm in one direction. A higher X-Max value means that the subwoofer can produce deeper tones without distortion, which ensures powerful and clear bass. This feature is particularly important in a subwoofer, as it directly contributes to the volume and clarity of the bass output, essential for your listening experience with bass-heavy music. With this X-Max value, the GTI124 demonstrates its ability to perform powerfully across various music genres.

Wie verhält sich die Aluminiummembran des GTI124 in der Praxis?

In practice, the aluminum diaphragm of the Crunch GTI124 offers several advantages. It is not only lightweight but also extremely rigid, which helps minimize distortion even at high volumes. The aluminum diaphragm can respond quickly to impulses, increasing precision in the reproduction of bass tones. This choice of material improves overall resonance, making bass sounds clearer and more detailed. Furthermore, the material ensures reduced heat buildup, which favors the longevity of the subwoofer in intense use. This construction is particularly ideal for high-fidelity enthusiasts.

Wie gut ist die Effizienz des GTI124 Subwoofers gemessen an seinem Klangdruckpegel?

The Crunch GTI124 demonstrates a remarkable efficiency with a sensitivity rating of 88 dB at 2.83 V/m. This value indicates the sound pressure level that the subwoofer produces at a specific input level. A higher dB value means that the subwoofer plays louder without requiring additional amplifier power. This helps achieve a higher volume while maintaining a consistent power supply and allows the subwoofer to operate with impressive volume even at lower power. Thus, the GTI124 is not only suitable for smaller amplifiers but can also deliver its maximum performance in a variety of setups.

Welche Vorteile bieten die Druckterminals beim GTI124 für die Installation?

The Crunch GTI124's terminal connections significantly simplify installation, as they allow for easy and tool-free connection of the speaker cables. These terminals are designed to ensure a secure hold of the cables, which is particularly advantageous when the subwoofer is frequently used in moving environments like a vehicle. The quick connection not only avoids installation frustrations but also minimizes potential contact issues compared to traditional screw connections. For the person who prefers DIY installs, these terminals enable a clean and professional setup without unnecessary installation effort.

Massive MiniMonster!

What a Minimonster, 18Liter ported box,tuned to 32hz and plays very loud and even good on lows. Even when i'm underpowering and only giving 350-400watts max. I really love this 6,5 monster, also the aluminium basket is very strong and solid and has great venting for the voice coil. Having rubber surround and carbon fiber cone just makes this even more indestructible

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.
