This feature eliminates the need to manually turn the subwoofer on and off, simplifying operation. The rationale behind this technology is based on the distinction between signal and noise levels, preventing unwanted power on or off.

This adjustment allows for better alignment of the sound waves of the subwoofer with the main speakers of the car or home setup, thereby avoiding phase issues and acoustic dips. Especially in complex audio setups where multiple speakers work together, phase management is crucial for clear and precise bass. The switch also helps to compensate for speaker orientations that are not ideal by improving the harmonic balance between the audio components, thus expanding the overall sound volume.

This variety of connections ensures that the QB201A can be easily integrated into existing setups without requiring extensive modifications. The advantage of these input options is particularly evident in custom audio systems.

The advantage of this filter is particularly evident when used in conjunction with existing speaker systems.

Aluminum helps reduce vibrations, leading to clearer and distortion-free bass reproduction. The thermal properties of the material also ensure effective heat dissipation even at high volumes, supporting the performance of the internal amplifier. Especially in complex sound scenarios that require constant power delivery, the housing of the QB201A unleashes its full potential by enhancing sound accuracy and device reliability.

Wie wirkt die Basspegel-Fernbedienung für den QB201A auf die Handhabung?

This feature is particularly useful when listening to different music genres and a quick adjustment of the bass level is required without having to change the settings on the main device.

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!
