Frequent questions about Power Tuned 9921b

Welche Leistung bietet der Power Tuned 9921b Subwoofer?

The Power Tuned 9921b Subwoofer from DD Audio impresses with an RMS power of 2500 watts and a peak power of 10000 watts. This immense load capacity allows for powerful and clear reproduction of deep bass. These performance features are particularly advantageous for listeners who value exceptional bass sound, especially at high volumes. The combination of high power and the patented ferrite magnet system ensures lossless sound reproduction that meets even the most demanding requirements. Such power levels are rare in commercially available models, which is why the 9921b is a special recommendation for sound enthusiasts.

Welche Impedanz-Optionen sind beim Power Tuned 9921b verfügbar?

The Power Tuned 9921b subwoofer offers two impedance options: dual 1 ohm or dual 2 ohm. These options allow for high flexibility to adapt the subwoofer to different amplifier configurations. Especially when you want to operate multiple subwoofers in a system, choosing the right impedance is crucial for optimal performance and overall sound quality. With the correct setting, you can minimize distortion and optimize the performance of the entire audio system. This is particularly important when you aim for high volumes without compromising quality.

Welche Frequenzen kann der Power Tuned 9921b wiedergeben?

The playback range of the Power Tuned 9921b subwoofers extends from 10 Hz to 500 Hz. This bandwidth provides an excellent foundation for the reproduction of deep bass frequencies, which are crucial in music and film soundtracks. Particularly, the ability to reproduce extremely low frequencies at 10 Hz sets it apart from many competing products and is ideal for bass enthusiasts. Combined with its high power capacity, this frequency range ensures that the subwoofer delivers exceptional performance in both home theater applications and professional audio settings.

Wie beeinflusst die gerippte Schaumstoff-Sicke die Leistung des Subwoofers?

The ribbed foam surround of the Power Tuned 9921b significantly contributes to its sound precision and durability. This special design ensures greater stability at high excursions, which in turn minimizes distortion. This feature is important to ensure that the subwoofer maintains clear and precise reproduction even at high volumes. The high-quality foam surround also supports smooth movement of the speaker, which ensures consistent sound reproduction across its entire frequency range. This is a significant advantage, especially with bass-intensive music.

Was sind die Thiele-Small-Parameter des Power Tuned 9921b?

The Thiele-Small parameters of the Power Tuned 9921b subwoofer include a resonance frequency (Fs) of 26.24 Hz, a mechanical quality factor (Qms) of 5.265, an electrical quality factor (Qes) of 0.51, and a total quality factor (Qts) of 0.47. The equivalent volume (Vas) is 161.9 liters. These parameters are crucial for the calculation and design of speaker enclosures to achieve optimal acoustic performance. They influence aspects such as bass depth and sound conversion efficiency. These values are particularly interesting for technically skilled users who develop custom sound solutions.

Wie ist das Magnetgewicht des Power Tuned 9921b und warum ist es wichtig?

The Power Tuned 9921b features an impressive magnet weight of 1500 Oz. A heavier magnet weight contributes to increasing the force at the voice coil, which improves the efficiency of sound conversion. This is particularly relevant when reproducing low frequencies, where a stronger magnetic force is needed to generate the required acoustic pressure. A heavier magnet weight can also help increase the speaker's load capacity and minimize distortion even at maximum power input, making the 9921b an ideal subwoofer for demanding audio systems.

Welche Materialien werden für das Gehäuse des Power Tuned 9921b verwendet?

The housing of the Power Tuned 9921b is made from a robust aluminum die-cast material. This choice of material offers several advantages: aluminum is not only extremely durable and resistant to high temperatures and mechanical stresses, but it also provides the subwoofer with significant stability, which is crucial for minimizing cabinet vibrations. This enables clearer and cleaner bass reproduction. Additionally, the die-cast construction contributes to structural integrity, which in turn preserves the sound precision of the subwoofer over time, regardless of operating conditions.

Welche Abmessungen hat der Power Tuned 9921b und wie passen diese in ein Fahrzeug?

The Power Tuned 9921b is a 21-inch subwoofer, which corresponds to a diameter of 53 cm. This size is considerable and requires a correspondingly large amount of space for installation in a vehicle. If you plan to install the subwoofer in a car, it is important to ensure that there is enough room for enclosure integration and ventilation to avoid overheating. Although specific vehicle models are not specified, the subwoofer is more likely to fit in larger vehicles such as SUVs or vans. A suitable placement area would be the trunk or a specially designed bass box.

Was macht das Ferrit-Magnetsystem des Power Tuned 9921b besonders?

The patented ferrite magnet system of the Power Tuned 9921b is special because it offers higher efficiency in energy conversion, thus optimizing sound quality even at high volumes. Ferrite magnets are known for their stability and ability to ensure high performance even under intense use. This property makes the subwoofer ideal for users who expect consistently high-quality bass without loss of performance. The ferrite magnet system also allows for finer tuning of sound waves, resulting in precise and powerful bass reproduction across the entire frequency range. This is particularly advantageous for dynamic music pieces.

Welche Vorteile bietet der 4" Spulendurchmesser des Power Tuned 9921b?

The 4 inch (101.6 mm) spool diameter of the Power Tuned 9921b has several advantages. A larger spool diameter allows for more windings and a larger wire diameter, which improves heat dissipation and increases the lifespan of the coil. This feature is particularly important when the subwoofer is operated at high power for extended periods. A larger diameter also contributes to overall performance, as more energy can be converted into acoustic power. This is crucial for achieving the high power levels for which this subwoofer is known and contributes to a powerful and clear sound image.

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!
