Wie ist die Signalverarbeitung im Quantum QL812SP konfiguriert?

The Quantum QL812SP features a high/low/bandpass filter with a variable cutoff frequency of 6 to 48 dB and can adjust the phase position and delays from 0 to 20 ms in 0.01 ms steps. This detailed adjustability allows for precise tuning of the frequency response to the individual needs and conditions of the vehicle or room. With the integrated subwoofer controller and input mixer, frequency ranges can be controlled with great accuracy to achieve optimal sound balance. These options allow for highly personalized sound tuning.

Welche Verbindungsmöglichkeiten bietet der Quantum QL812SP?

The Quantum QL812SP offers numerous connections: 8 RCA inputs, 8 high-level inputs with EPS PRO range up to 40 V/RMS, an optical and coaxial S/PDIF input with 192 kHz at 24 Bit, and a Bluetooth® input. This facilitates integration into various system configurations, as both analog and digital input options are covered. Additionally, there is a USB Type B port for PC software for detailed sound process programming, as well as an RJ45 port for remote control options. Notably, the integrated Bluetooth® receiver with aptX HD for high-quality audio streaming is particularly highlighted.

These dimensions are particularly suitable for users who prefer a discreet installation.

Welche Sensitivitätseinstellungen hat der Quantum QL812SP?

The Quantum QL812SP features separate input sensitivity settings for low and high level inputs. The low level inputs have a sensitivity range of 1 to 6 V/RMS, while the high level inputs offer greater flexibility with either 1 to 15 or 15 to 45 V/RMS. This range allows the user to connect the DSP to a variety of different signal sources, whether directly from the car radio or from an amplifier with high-level outputs. The flexible sensitivity range ensures that the QL812SP maintains full signal integrity regardless of the input source.

Wie hoch ist der Signal-Rauschabstand des Quantum QL812SP?

The Quantum QL812SP offers a signal-to-noise ratio of 111 dB with its analog input and even 117 dB with the digital input, both A-weighted. This high signal-to-noise ratio is crucial for reproducing the finest audio details without disturbing background noise. The high values ensure that even at high volumes or when using highly sensitive speakers, the sound remains clean and rich. Especially with high-quality audio content, the advantages of a high signal-to-noise ratio are reflected in clear and distortion-free playback that delights audiophile listeners.

Welche Klirrfaktoren hat der Quantum QL812SP?

The Quantum QL812SP impresses with extremely low distortion factors: The analog input has a distortion factor of less than 0.001%, while the digital input is even below 0.0004%.

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!
