Frequently Asked Questions about Power Tuned 3518i ESP

What features does the Power Tuned 3518i ESP offer in terms of energy efficiency?

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 powerful motor combined with the long gap/long coil topology provides optimal sound fidelity and performance. These features contribute to remarkable energy efficiency, maximizing performance while also extending the lifespan of the Subwoofer.

How does the Carbon Fiber Blend Cone (CFB) affect sound quality in the 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.

What technical specifications are important for the installation of the Power Tuned 3518i ESP?

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 mounting 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 ohms or dual 4 ohms, 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 realize its potential.

How does the Tuned Spider System (TSS) enhance the performance of the 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 fine-tuning 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.

How does the V-ROM surround affect the bass reproduction of the Power Tuned 3518i ESP?

The V-ROM surround of the Power Tuned 3518i ESP provides ultimate linear control at high displacement, which directly impacts the dynamics and precision of the 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 offers the advantage of keeping the bass reproduction clear and powerful even under extreme conditions.

What advantages does the aluminum die-cast basket offer for the Power Tuned 3518i ESP?

The aluminum die-cast basket in 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. Combined with high structural integrity, the aluminum die-cast basket enhances the overall performance of the Subwoofer and allows for even the most demanding bass notes to be reproduced in detail and precision, making it an essential component of the design.

What impedance options does the Power Tuned 3518i ESP offer and how do they affect performance?

The Power Tuned 3518i ESP from DD Audio offers impedance options in dual 2 ohm or dual 4 ohm, providing great flexibility for adapting to existing amplifier systems. These options significantly influence 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 for 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 beneficial in varying acoustic environments.

For which frequency ranges is the Power Tuned 3518i ESP optimally suited?

The Power Tuned 3518i ESP is 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 home cinema or music concerts in the car—the Subwoofer shows its strengths. The seamless integration into existing sound systems is ensured by its ability to process different frequencies with high accuracy.

What factors make the Power Tuned 3518i ESP a precise 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 faithful 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 relationship 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.

What impact does the resonance frequency of the Power Tuned 3518i ESP have on its performance?

The resonance frequency (Fs) of the Power Tuned 3518i ESP is 29.61 Hz, a value that allows for 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 layers are significant. The Fs values, in combination with other parameters like Qms and Qes, contribute to the overall accuracy of reproduction and enable the Subwoofer to deliver consistent performance even at different volume settings, which is an outstanding feature for audio enthusiasts.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.
