It is important to minimize the distance to the power source and signal connections to avoid losses or interference. The correct installation includes connecting the high-level inputs and the RCA outputs, which are not symmetrical. Make sure that the adapter is securely held and cannot slip. The EPS technology prevents error messages in the vehicle, making the installation particularly straightforward.

Welche Frequenzübertragungsbandbreite bietet der HLC4?

The HLC4 features an impressive transmission frequency of 5 Hz to 60 kHz, which encompasses both the deepest bass and the highest treble in the context of audio systems. This bandwidth ensures that no detail of the music is lost, whether it involves low bass notes or sharp highs. The transmission frequency is critical for fidelity and ensures that sound distortions are avoided. Users of the HLC4 can expect a precise and complete sound representation, which is particularly important in high-quality audio installations. This enables a comprehensive music experience.

Welche Automarken sind mit dem HLC4 direkt kompatibel?

The HLC4 from ESX is designed to work universally with most OEM factory radios. Although no specific car brands are mentioned in the product description, compatibility is often given with common brands. Important criteria for its use include delivery with correct signal level consideration and EPS technology, which has been explicitly developed to function smoothly with modern vehicles. Due to the general design language and electrical specifications (10-16V operating voltage), the HLC4 can be integrated into numerous vehicle models from brands like BMW, Audi, or Volkswagen. A precise check of specific compatibility with the manufacturer would be advisable.

Welche Installationsbesonderheiten gibt es beim HLC4?

The HLC4 offers a compact design through its modern SMD technology, allowing for flexible installation. A special highlight is the plug & play capability, which enables even non-technical users to install and operate the adapter relatively effortlessly. When choosing a location in the vehicle, you should ensure that all connections are secure and protected from external influences. It is advisable to position the device so that the LED indicators for the operating status and any clipping are easily visible. This facilitates monitoring and adjustment of the level controller if necessary. The installation site should ideally be free from mechanical impacts.

Wie beeinflusst die Kanalseparation des HLC4 die Audioleistung?

The HLC4 offers a channel separation of 80dB, ensuring that signals do not cross over between channels. This high separation allows for precise representation of stereo sources by cleanly isolating and processing the influences of the left and right channels.

Massive MiniMonster!

What a Minimonster, 18Liter ported box,tuned to 32hz and plays very loud and even good on lows. Even when i'm underpowering and only giving 350-400watts max. I really love this 6,5 monster, also the aluminium basket is very strong and solid and has great venting for the voice coil. Having rubber surround and carbon fiber cone just makes this even more indestructible

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.
