Frequent questions about GPX1250.1D

Wie beeinflusst der Subsonic-Filter des GPX1250.1D den Klang?

The subsonic filter of the Crunch GPX1250.1D amplifier covers a frequency range of 10 to 35 Hz and is designed to eliminate unwanted low frequencies that could unnecessarily burden your speaker system. By specifically filtering out these very low frequencies, the performance and efficiency of your speaker system are improved. Especially when you want to achieve high levels, the subsonic filter prevents too much energy from being wasted on frequencies that cannot be effectively reproduced. This allows for clearer reproduction of low frequencies and protects your speakers.

Welche Einstellmöglichkeiten bietet der Tiefpass-Filter beim GPX1250.1D Verstärker?

The low-pass filter of the Crunch GPX1250.1D amplifier is adjustable from 40 to 150 Hz, allowing you to determine the maximum frequency to be reproduced by your subwoofer. This adjustability helps you create a clean transition between your subwoofer and the other speakers in your system. Depending on the characteristics of your audio system and the acoustic conditions of your vehicle, you can set the ideal cutoff point. This feature is particularly useful when you aim for the ideal harmony between different components of your audio system.

Wie funktioniert der Bass Boost bei GPX1250.1D?

The bass boost of the Crunch GPX1250.1D amplifier allows for an increase in bass levels ranging from 0 to 12 dB, enabling you to adjust the bass level according to your sound preferences. By turning the corresponding knob, you can specifically enhance the bass range, which is particularly beneficial for bass-heavy music genres like hip-hop or electronic music. This adjustability makes it possible to shape the bass so that it harmonizes with the other frequencies without making the sound seem unbalanced. A practical feature for full, dynamic bass reproduction.

Was ist die Funktion der Phase Shift bei Crunch GPX1250.1D?

The phase shift function of the GPX1250.1D amplifier can be adjusted from 0 to 180° and is crucial for synchronizing the phase of your subwoofer with the other speakers in your system. This adjustment helps to compensate for phase shifts that can occur due to the different distances of the speakers from the listener or due to room acoustics. By making precise adjustments, a more coherent bass reproduction can be achieved, resulting in a clearer and more powerful overall sound image. This function is particularly useful if you value precise sound staging.

Welche Eingangsmöglichkeiten hat der GPX1250.1D Verstärker?

The Crunch GPX1250.1D is equipped with both RCA and high-level inputs, allowing you flexible connectivity to various audio sources. RCA inputs are optimal for connecting aftermarket audio sources or amplifiers, while the high-level inputs allow you to use the factory systems of a vehicle without additional conversion devices. These diverse connection options facilitate the integration of the GPX1250.1D into various audio environments and are a significant advantage for those who use both factory systems and custom audio systems.

The GPX1250.1D amplifier from Crunch is capable of delivering a maximum power of 1250 watts at 1 Ω. This high power capacity makes it ideal for use with powerful subwoofers and for reproducing deep, powerful bass signals. The ability to generate up to 1250 watts means that this amplifier also provides sufficient power reserves for more demanding installations, ensuring clear and distortion-free sound even at high volumes. A typical application can be found in vehicles that focus on impactful sound and strong bass.

Welche Rolle spielt die Basspegel-Fernbedienung beim GPX1250.1D?

The bass level remote control included with the Crunch GPX1250.1D provides you with the convenience of adjusting the bass level immediately and effortlessly to suit your listening habits. Connected to the amplifier, it allows you direct control over the bass output without having to physically adjust the amplifier itself. Especially while driving, you can make quick and on-demand adjustments to create the optimal sound depending on the music genre or personal preference.

These measurements allow for flexible installation in many types of vehicles and provide options to mount the amplifier discreetly without taking up too much space. Thanks to its compact size, the GPX1250.1D can be easily accommodated in trunks, under seats, or in custom-made amplifier enclosures. This is particularly advantageous in smaller vehicles or anywhere space is limited. This sizing enables a subtle integration of the amplifier into the vehicle system.

Was bewirkt die automatische Einschaltfunktion im GPX1250.1D?

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!
