Especially when you need a space-saving design, the A8 is ideally suited due to its dimensions. The specific measurements guarantee perfect sound performance, especially in smaller enclosures.

Welche Klangqualität bietet der A8 Subwoofer in einem 19-Liter-Gehäuse?

In a 19-liter bass reflex enclosure, the A8 subwoofer from RS Audio unfolds its full sonic potential. The tuned frequency response starts at 35.06 Hz, and the sound pressure level is at 84.00 dB SPL. These parameters ensure that the subwoofer delivers powerful and precise bass. The BL factor of 12.79 and a moving mass of 82.68 grams contribute to the impressive sound dynamics, making it ideal for discerning audio enthusiasts. The enclosure volume ensures that the A8 is capable of efficiently generating the desired sound pressure.

Ist der A8 Subwoofer mit meinem Auto kompatibel?

The compatibility of the RS Audio A8 subwoofer depends on the dimensions of the installation location in your vehicle. With a nominal diameter of 210 mm, a mounting depth of 124 mm, and a mounting hole of 184 mm, the subwoofer fits into many vehicle geometries that provide space for a 19-liter bass reflex enclosure. It is important to measure the available installation space accurately to ensure that the A8 can be integrated without any issues. If these dimensions are adhered to, the A8 is an excellent addition to your car audio system.

Wie beeinflussen die Q-Faktoren den Klang des A8 Subwoofers?

The Q factors of the RS Audio A8 subwoofer are crucial for the speaker's sound characteristics. With a Qms of 4.63, a Qes of 0.43, and a Qts of 0.40, these values determine the mechanical and electrical behavior of the subwoofer. A low Qts value allows for precise control over bass reproduction, resulting in a balanced and clear sound image. This balanced sound is particularly advantageous at high volumes, as distortions are minimized. The A8 is therefore ideal for music lovers who desire detailed bass.

Welchen Einfluss hat das Mms auf die Leistung des A8 Subwoofers?

The moving mass, Mms, of the RS Audio A8 subwoofer is 82.68 grams. This parameter affects the efficiency and frequency response of the subwoofer. A higher Mms can result in the speaker requiring more energy to achieve the same sound pressure levels, but it generally also handles lower frequencies better. The A8 subwoofer offers a good compromise between efficiency and deep bass reproduction due to this Mms value, making it ideal for delivering powerful and clear bass in a variety of audio setups.

Wie montiere ich den RS Audio A8 Subwoofer korrekt?

The RS Audio A8 subwoofer should ideally be installed in a bass reflex enclosure with a volume of 19 liters to ensure optimal sound quality. The installation depth is 124 mm and the mounting hole has a diameter of 184 mm. Before installation, it is advisable to measure the installation location accurately. Make sure that the enclosure includes a reflex tube with a diameter of 60 mm and a length of 280 mm. Precise installation ensures that the A8 can fully unleash its sound quality, which is particularly important for reproducing the lowest bass frequencies.

Welche Thiele-Small-Parameter sind besonders hervorzuheben?

The Thiele-Small parameters are crucial for the performance of the RS Audio A8 subwoofer. The Qts value of 0.40, Fs of 35.06 Hz, and BL of 12.79 are particularly noteworthy as they significantly influence bass reproduction. A low Qts value helps minimize distortion and unwanted resonances, while the resonant frequency Fs sets the lower cutoff frequency. The BL value indicates the force transmitted to the voice coil, which is critical for impulse fidelity and level accuracy. These parameters make the A8 a powerful subwoofer for audiophiles.

Was ist der Frequenzgang des A8 Subwoofers?

The frequency response of the RS Audio A8 subwoofer starts at 35.06 Hz, which means it is capable of accurately reproducing very low bass frequencies. This low cutoff frequency is the result of the continued development and tuning of the subwoofer to meet the demands of discerning audio setups. This specification allows the A8 to produce deep-reaching sounds, making it particularly attractive to music lovers seeking excellent bass volume and clear, deep tones.

Wie wirkt sich der SPL-Wert des A8 Subwoofers auf das Hörerlebnis aus?

The sound pressure level (SPL) of the RS Audio A8 subwoofer is 84.00 dB. Such an SPL value indicates that the subwoofer is relatively efficient when it comes to converting acoustic energy into audible volume. This means you can achieve a high volume even at lower amplifier power levels. However, be aware that increasing the volume will inevitably also increase the power required from the amplifier. With an SPL of 84.00 dB, the A8 offers a balanced balance between efficiency and volume, optimal for various audio applications.

Was macht den A8 Subwoofer von RS Audio einzigartig?

The RS Audio A8 subwoofer impresses with a combination of precise technical parameters and a design specifically developed for powerful bass reproduction. With an Fs of 35.06 Hz, a Qts of 0.40, and a BL of 12.79, the A8 delivers an optimal sound image. The specific dimensions of 210 mm nominal diameter, 124 mm installation depth, and a 19-liter enclosure optimization offer flexibility and quality at the same time. These features make the A8 an excellent choice for audio enthusiasts who value fidelity and powerful sound in a compact format.

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!
