ESP Subwoofer Features

  • Carbon Fiber Blend Cone (CFB) - The CFB composition uses an effective carbon fiber-based cocktail to provide you with the highest strength-to-weight ratio in the industry.
  • Vario-Density Extended Range of Motion Surround (V-ROM) - Offers ultimate linear control at high excursion while enabling dynamically sounding bass reproduction. The control ribs are compressed to a lower density than the main surround body to allow a seamless control system. The harder you control it, the more control you get.
  • Tuned Spider System (TSS) - Each suspension is tuned for specific performance characteristics, e.g., High Definition, Power Handling, X-Stiff Control.
  • Super-Frame (SFrame) - Maximizes spider diameter, cone diameter, suspension excursion, and acts as a secondary shorting ring while providing additional heat dissipation for better heat flow from the coil.
  • SuperCharge Option available!

Frequent questions about Power Tuned 3518i ESP


Welche Besonderheiten bietet der Power Tuned 3518i ESP in Bezug auf Energieeffizienz?

The Power Tuned 3518i ESP from DD Audio is characterized by its design with low moving mass, which allows for increased energy efficiency. This means that less energy is required to operate the subwoofer, leading to a more efficient use of the built-in 800-degree thermoplastic voice coil system. Additionally, the ultra-high energy of the strong motor combined with the long gap/long coil topology provides optimal sound fidelity and performance. These features contribute to remarkable energy efficiency that not only maximizes performance but also extends the lifespan of the subwoofer.

Wie beeinflusst das Carbon Fiber Blend Cone (CFB) die Klangqualität beim Power Tuned 3518i ESP?

The Carbon Fiber Blend Cone (CFB) in the Power Tuned 3518i ESP provides an outstanding strength-to-weight ratio that is unmatched in the industry. This carbon fiber composition allows the cone to withstand high loads without losing sound quality. The strength of the material minimizes distortion and ensures precise, clear bass even at higher volumes. The CFB design helps support the subwoofer with impressively consistent sound reproduction through its efficiency and robustness, which is a crucial advantage for music lovers.

Welche technischen Daten sind für die Installation des Power Tuned 3518i ESP wichtig?

For the installation of the Power Tuned 3518i ESP, the dimensions and technical values are particularly important. The 18-inch subwoofer has a diameter of 46 cm and requires a certain installation depth to function optimally. Key technical specifications include an RMS power handling of 1200 watts and a peak power handling of 4800 watts. The impedance options, either dual 2 ohm or dual 4 ohm, allow for versatile adaptation to existing audio systems. With an Xmax of ±17.5 mm and a magnet weight of 350 Oz, a stable mounting is required to fully exploit its potential.

Wie verbessert das Tuned Spider System (TSS) die Leistungsfähigkeit des Power Tuned 3518i ESP?

The Tuned Spider System (TSS) in the Power Tuned 3518i ESP is designed to support specific performance characteristics such as high definition, power handling, and X-Stiff Control. It optimizes the motion control of the diaphragm and ensures that the displacement remains linear at high sound levels. The TSS structure contributes to the fine-tuning of the suspension, allowing for clear and distortion-free music playback even under intense use. Specifically developed for the Power Tuned 3518i ESP, the TSS maximizes playback quality under high loads and maintains sound accuracy.

Wie wirkt sich die V-ROM-Sicke auf die Basswiedergabe des Power Tuned 3518i ESP aus?

The V-ROM surround of the Power Tuned 3518i ESP offers ultimate linear control at high excursions, which directly affects the dynamics and precision of bass reproduction. The varying density in the surround allows for flexible sound control and enhances resonance at low frequencies. Especially during loud and bass-intensive music sessions, the V-ROM surround ensures precise cone movement without causing distortion. This provides the advantage that bass reproduction remains clear and powerful even under extreme conditions.

Welche Vorteile bietet der Aluminium Druckgusskorb für den Power Tuned 3518i ESP?

The aluminum die-cast basket of the Power Tuned 3518i ESP has several advantages. It provides a stable base for the subwoofer, minimizes mechanical resonances, and offers better heat dissipation, which extends the lifespan of the system. The material ensures a stable, torsion-resistant chassis that efficiently transmits vibrations. In combination with high structural integrity, the aluminum die-cast basket enhances the overall performance of the subwoofer and allows it to reproduce even the most demanding bass notes in detail and precision, making it an essential component of the design.

Welche Impedanz-Optionen bietet der Power Tuned 3518i ESP und wie beeinflussen sie die Performance?

The Power Tuned 3518i ESP from DD Audio offers impedance options in dual 2 ohm or dual 4 ohm, providing great flexibility in adapting to existing amplifier systems. These options significantly affect the overall performance of the system. A lower impedance, such as dual 2 ohm, allows for drawing more power from the same amplifier, which is useful when reproducing high volume levels. Conversely, dual 4 ohm offers a higher, more stable overall impedance that protects the system and ensures consistent sound performance, which is particularly advantageous in different acoustic environments.

Für welche Frequenzbereiche ist der Power Tuned 3518i ESP optimal geeignet?

The Power Tuned 3518i ESP is optimally designed for a playback range of 10 Hz to 500 Hz. This frequency range allows for comprehensive bass reproduction, covering both the lowest tones and musically harmonious mids. Especially in applications that require a wide range of bass frequencies—such as in home cinema or music concerts in the car—the subwoofer demonstrates its strengths. The seamless integration into existing sound systems is ensured by its ability to process different frequencies with high accuracy.

Welche Faktoren machen den Power Tuned 3518i ESP zu einem präzisen Subwoofer?

The Power Tuned 3518i ESP achieves precise bass reproduction through a combination of advanced technologies. The powerful motor with ferrite magnet system and the long gap/long coil topology enable accurate sound generation. Furthermore, the lossless linear suspension contributes to sound fidelity. The mechanical and electrical quality with values of Qms 4.38 and Qes 0.50 ensures a balanced equilibrium between mechanical damping and electrical influence, enhancing control and precision. These technological features make the Power Tuned 3518i ESP the ideal subwoofer for highly demanding applications.

Welche Auswirkungen hat die Resonanzfrequenz des Power Tuned 3518i ESP auf seine Leistung?

The resonance frequency (Fs) of the Power Tuned 3518i ESP is 29.61 Hz, a value that enables deep bass reproduction. A lower resonance frequency supports the generation of clear deep bass tones, particularly useful in music genres like dubstep or orchestral pieces, where deep bass lines are significant. The Fs values, in combination with other parameters such as Qms and Qes, contribute to the overall accuracy of the reproduction and allow the subwoofer to deliver consistent performance even at different volume settings, which is an outstanding feature for audio enthusiasts.
