Such an advanced motor design allows this speaker to process frequencies accurately and highlight sonic details that are often lost in conventional speakers. Additionally, the motor concept provides increased excursion, which expands the dynamic range and thus enables a more powerful and differentiated sound.

Wie beeinflussen die Thiele Small Parameter den Klang des Reference RS225?

The Thiele Small parameters of the Dayton Audio Reference RS225, such as mechanical quality factor (Qms), electrical quality factor (Qes), total quality factor (Qts), and resonance frequency (Fs), play a crucial role in determining the acoustic performance of the speaker. For example, the 4-ohm version of the RS225 has a Qts of 0.41 and an Fs of 33 Hz, while the 8-ohm version has a Qts of 0.38 and an Fs of 28.3 Hz. These parameters influence the bass behavior and efficiency of the speaker. A low Qts value generally means that the speaker is well-suited for sealed enclosures, resulting in tighter bass reproduction. These specific parameters help to optimally integrate the speaker into an enclosure to achieve the desired sound characteristics.

Wie installiere ich den Dayton Audio RS225 korrekt in einem Lautsprechergehäuse?

For the correct installation of the Dayton Audio RS225 in a speaker enclosure, it is important to carefully observe the dimensions. The outer diameter is 223 mm, the cutout diameter is 184 mm, and the overall depth is 92 mm (4 Ohm) or 89 mm (8 Ohm). The enclosure holes must accommodate the spacing of the six mounting holes. It is advisable to perform a suitable enclosure volume calculation. For the 4-ohm model, a closed enclosure volume of about 14.15 liters is recommended, while the 8-ohm model requires a volume of 12.45 liters.

Welche Vorteile bietet der Aluminium-Phasenanschluss des RS225?

The massive aluminum phase connector of the Dayton Audio Reference RS225 offers a variety of acoustic advantages. Primarily, it reduces mechanical distortions that typically occur at high displacements by minimizing phase anomalies in sound reproduction. This leads to improved sound clarity and a more homogeneous sound radiation. The phase connector helps optimize the temperature of the voice coil, which reduces thermal stress and contributes to a longer lifespan of the speaker. The aluminum construction also provides the advantage of increased stability, positively affecting the dynamic frequency range, especially at low frequencies, where bass notes are reproduced more clearly and powerfully.

Welche Resonanzfrequenz hat der RS225 und weshalb ist sie wichtig?

The resonance frequency (Fs) is a crucial parameter of the Dayton Audio Reference RS225. For the 4-ohm model, it is 33 Hz, and for the 8-ohm model, it is 28.3 Hz. This frequency indicates the point at which the speaker begins to vibrate spontaneously and operates most efficiently. A low resonance frequency, like that of the RS225, favors deep bass reproduction and ensures that the speaker is capable of delivering authentic and powerful bass notes. The precise tuning of the speaker in the enclosure is essential to optimally utilize this resonance frequency, resulting in clean and accurate sound reproduction, especially in applications requiring low frequencies, such as in home theater or music systems.

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!
