Welche Materialien werden im Sapphire 165/3 MK II Lautsprecherset verwendet?

For the tweeters of the Sapphire 165/3 MK II, a silk dome is used as cone material, which ensures a clear and soft high-frequency range. The woofer is equipped with a paper membrane, known for its natural and warm sound in the mid and low-frequency range. This combination of materials significantly contributes to detailed and balanced sound reproduction and is ideal for music lovers who value precision and sound fidelity. The choice of materials has a lasting impact on the sound characteristics of a speaker.

Wie beeinflusst die Impedanz des Sapphire 165/3 MK II die Klangqualität?

The Sapphire 165/3 MK II from RS Audio has an impedance of 4 Ω, which allows for standard compatibility with a variety of amplifiers. A lower impedance means that the speaker draws more power from the amplifier, potentially leading to a higher volume at the same amplifier output. This characteristic can enhance the overall volume and sound dynamics of the speaker without losing auditory details. For optimal operation, the amplifier should be adjusted accordingly to ensure full sound quality.

Wie spielt die Frequenzweiche des RS Audio Sapphire 165/3 MK II eine Rolle?

The crossover of the Sapphire 165/3 MK II has a design of 6/6 dB, which ensures a harmonic separation and tuning between the woofers and tweeters. This crossover frequency ensures that each driver only reproduces the significant frequencies, which reduces distortion and creates clarity in the sound image. This property is extremely important, especially with more complex pieces of music, as it noticeably improves sound quality and detail fidelity. It is recommended to adjust the speakers according to the crossover for the optimal listening experience.

Welche Dimensionen hat das Sapphire 165/3 MK II Lautsprecherset?

The Sapphire 165/3 MK II fits into many vehicles due to its compact dimensions. The woofer with a diameter of 165 mm and a mounting depth of 72 mm is important for placement in door panels or dashboards. The tweeter, with a diameter of 50 mm and a mounting depth of 16 mm, is ideal for flexible mounting options. For improved sound quality, installation should take place in an acoustically suitable area to avoid unwanted resonances.

This is ideal for setups where less powerful amplifiers may be used without compromising sound quality or volume. A high efficiency is particularly advantageous in situations where volume and clarity are needed.

The Sapphire 165/3 MK II offers a balanced and detailed sound image through the combination of silk dome tweeters and paper cone woofers. The frequency response of 44 Hz to 20,000 Hz allows for accurate reproduction of lows, mids, and highs, while the acoustic separation provided by the crossover ensures a clean sound representation. Music lovers who appreciate natural and warm tones will particularly notice the quality of these speakers. The efficiency of the speaker is crucial to optimally utilize the power reserves during normal use.

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!
