Frequent questions about Riot 8PWR

Welche Leistung bietet der Riot 8PWR Lautsprecher?

The Riot 8PWR, developed by B2 Audio, features an impressive rated power of 150 watts, supported by its robust construction. When needed, it can deliver a peak power of up to 300 watts, making it the ideal choice for demanding sound applications in your vehicle. With a sensitivity of 94.7 dB, it ensures efficient sound reproduction, allowing for clear and dynamic sound even at higher volumes. Its design with a ferrite magnet and a 1.5-inch KCCAW voice coil makes the speaker reliable and ready to withstand even intense musical demands.

Welche Frequenzen kann der Riot 8PWR wiedergeben?

The Riot 8PWR from B2 Audio has been designed with a frequency response of 80 Hz to 6 kHz, making it a versatile mid-bass driver for numerous audio projects. This range allows the speaker to efficiently reproduce deep bass as well as clear mids. The resonance-free frequency of 90 Hz helps minimize unwanted vibrations, while the UV-treated, weather-resistant paper for the diaphragm ensures the longevity of audio quality even under various environmental conditions.

Welche Materialien werden beim Riot 8PWR verwendet?

The Riot 8PWR speaker uses a combination of high-quality materials to ensure excellent audio quality. The diaphragm is made of UV-treated, weather-resistant paper, which ensures durability, while the 1.5-inch voice coil is made of KCCAW (Copper-Clad Aluminum Wire) and provides optimal electrical conductivity. The ferrite magnet, weighing 23 oz, forms a stable base for sound reproduction. Additionally, the double U-shaped fabric surrounds prevent vibrations from affecting sound quality.

Was sind die technischen Abmessungen des Riot 8PWR?

The B2 Audio Riot 8PWR has precise technical dimensions that allow for accurate installation. The overall diameter is 205 mm and the diameter of the sound cutout is 183 mm, making it suitable for numerous installation locations. The bolt circle diameter is 194 mm. Its total depth of 90 mm and installation depth of 82 mm make it compact enough for versatile applications. With a net weight of 1.7 kg, this speaker is robust without being too heavy, which simplifies installation.

Wie beeinflusst die Impedanz die Leistung des Riot 8PWR?

The nominal impedance of the Riot 8PWR speaker is 4 ohms, which provides an ideal balance between power consumption and output power. A lower impedance can increase the load on the amplifier, but it also means that the amplifier can deliver more power at the same voltage. This 4-ohm design makes the speaker versatile for use in various audio setups, as it is compatible with most common amplifiers without the need for adapters. This promotes efficient energy transfer and minimal power loss in your audio system.

Welche Thiele-Small-Parameter charakterisieren den Riot 8PWR?

The Riot 8PWR from B2 Audio is precisely described by its Thiele-Small parameters, which clearly define its acoustic behavior. The resonance frequency value (Fs) is 90 Hz, while Re (series) is 3.8 Ohms, which affects the electrical properties. With a Qms of 4, a Qes of 0.94, and a total quality factor Qts of 0.76, these values provide insights into its efficiency and resonance. Cms (compliance at rest) is specified at 108 um/N, and the equivalent volume value (VAS) is 7.7 liters, which is of interest for the volume of the enclosure.

Wie installiere ich den Riot 8PWR im Auto?

To install the Riot 8PWR in the car, careful preparation is essential. First, check the installation dimensions: the overall diameter is 205 mm and the installation depth is 82 mm. Then measure the sound wall cutout (183 mm) at your intended installation location. If you have wider or narrower openings in your vehicle, an adapter ring may be necessary. Ensure that all electrical connections are clean and stable. The speaker should ideally be mounted in a stable bracket to minimize vibrations, which benefits optimal sound reproduction.

Wie erzeugt der Riot 8PWR sein Klangbild?

The B2 Audio Riot 8PWR produces its balanced sound profile through a combination of precisely tuned electronics and high-quality materials. The frequency response of 80 Hz to 6 kHz allows for the reproduction of both deep and clear mid frequencies. The ferrite magnet plays a central role by providing the necessary magnetic force to generate sound waves. The 1.5-inch KCCAW voice coil influences efficiency and sensitivity. Together with the UV-treated paper diaphragm, which minimizes vibrations, the speaker is characterized by crystal-clear sound reproduction.

Welche Vorteile bietet das SD von 223,9 cm² beim Riot 8PWR?

The diaphragm area diagram (SD) of the Riot 8PWR is 223.9 cm². This value is crucial for sound distribution, especially in the area of bass reproduction. A larger diaphragm area allows for a more efficient conversion of electrical signals into acoustic waves, resulting in a more powerful bass. Especially with a diameter of 8 inches, this large diaphragm area makes a difference in deep frequency reproduction. So, if you want to produce powerful and strong bass, this diaphragm design will make a significant contribution to your audio setup.

Wie trägt das UV-behandelte Papier zur Klangqualität bei?

The use of UV-treated, weather-resistant paper in the Riot 8PWR speaker has a direct impact on sound quality and durability. This treatment ensures that the diaphragm is not only extremely durable but also remains resistant to environmental influences such as moisture and UV radiation. This prevents unwanted changes in the speaker's sound profile, as the material remains shape-stable and no resonance errors occur. Especially when you want to enjoy music in outdoor environments or summer heat, this material composition guarantees consistent performance and consistently high sound quality.

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!
