Frequently Asked Questions about Colossus CX15D2

What are the performance specifications of the Hifonics Colossus CX15D2?

The Hifonics Colossus CX15D2 impresses with 4500 Watts RMS and a maximum power of 9000 Watts. This power is enabled by the massive 4-inch dual 2-ohm voice coils, which can withstand temperatures of up to 220°. The Subwoofer uses a triple magnet with 3 x 285 ounces to achieve extreme volume levels, such as 154 dB sound pressure at 100 liters volume. Thanks to its high power efficiency, the Colossus CX15D2 ensures unparalleled bass reproduction that meets the demands of SPL competitions. With a nominal impedance of 2 + 2 ohms, it easily adapts to various audio setups.

How is the Hifonics Colossus CX15D2 constructed?

The Colossus CX15D2 is built with an aluminum die-cast basket and a reinforced aluminum dust cap, ensuring a robust and stable structure. The diaphragm is made of hand-crafted paper, which is equipped with sewn-in leads to enhance durability. A double-stitched surround and dual Nomex spider with dual centering guarantee precise movements of the diaphragm. These construction features maximize performance and longevity, especially when the Subwoofer reaches its maximum sound pressure of 154 dB. The use of strong specialty glue also ensures integrity under extreme conditions.

What enclosure volume is the Hifonics Colossus CX15D2 designed for?

The Colossus CX15D2 is optimally designed for an enclosure volume of 100 liters to achieve its maximum sound pressure of 154 dB. The volume is a crucial factor that influences resonance characteristics and efficiency. An enclosure that is too small could reduce performance, while one that is too large could distort the sound. This volume is recommended for SPL applications to fully utilize the impressive performance specifications and to generate the remarkable bass pressure that this Subwoofer can deliver.

What technological features are integrated into the Hifonics Colossus CX15D2?

The Hifonics Colossus CX15D2 Subwoofer utilizes a range of advanced technologies, including triple magnets and 100 mm dual voice coils, to produce powerful bass. A key point is the 220° resistant aluminum-copper wire windings of the voice coils, which can withstand high thermal loads. Additionally, the double-stitched surround contributes to stability, while the dual-Nomex spider allows for precise speaker movement. These technologies combine to deliver outstanding SPL performance and enable maximum sound pressure development while maintaining sound quality.

What are the Thiele-Small parameters of the Hifonics Colossus CX15D2?

The relevant Thiele-Small parameters of the Hifonics Colossus CX15D2 include a resonance frequency (Fs) of 34 Hz, a total quality factor (Qts) of 0.39, and an equivalent volume (VAS) of 59 liters. These parameters are crucial for determining the acoustic properties and enclosure tuning. While the low value of Fs indicates deep bass capabilities, the Qts value indicates the damping behavior. The VAS value is relevant for enclosure volume calculations and the efficient use of the Subwoofer to achieve maximum bass frequencies without loss of power.

What materials are used in the Hifonics Colossus CX15D2?

The Hifonics Colossus CX15D2 uses a combination of materials to ensure high performance and durability. The aluminum die-cast basket provides a stable foundation, while the hand-crafted paper cone ensures optimal vibration properties. Sewn leads increase the robustness of the cone, and the reinforced aluminum dust cap offers additional protection. Dual-Nomex spider and double-stitched surrounds maximize movement precision. Special aluminum-copper wire windings of the voice coils ensure thermal resistance up to 220°, which is particularly important for loads of up to 4500 watts RMS.

What are the dimensions of the Hifonics Colossus CX15D2?

The Hifonics Colossus CX15D2 Subwoofer has an overall diameter specification of 358 mm and a depth of 260 mm. These dimensions are crucial for planning the installation position in the vehicle and for fitting into enclosures. During installation, it is important to ensure that there is enough space to guarantee proper performance. The installation flexibility is determined by these dimensions, allowing the subwoofer to be securely mounted in both sedans and SUVs with appropriate volume capacities, which is essential for optimal pulse performance.

Can the Hifonics Colossus CX15D2 be installed in my car?

The installation of the Colossus CX15D2 is possible in many vehicles, provided the available volume allows for an enclosure of about 100 liters. Staff at sound shops often recommend coordinating the installation depth of 260 mm and the diameter of 358 mm with the dimensions in the trunk or enclosure. Compatibility heavily depends on the design and space available in sedans and SUVs. Without considering these measurements, subwoofer performance may be compromised. Suitable for passionate audio engineers seeking room-filling bass power.

How does the dual-centered surround affect the performance of the Hifonics Colossus CX15D2?

The dual-centered surround of the Colossus CX15D2 plays an important role in performance by precisely controlling the movement of the diaphragm. This configuration ensures that the diaphragm remains stable even under high loads and that linear displacements are optimally executed. As a result, high sound pressure levels of up to 154 dB can be achieved without distortion or structural impairments. Together with the dual Nomex spiders, it ensures optimal centering and dynamic control, further enhancing the efficiency and lifespan of the subwoofer.

What advantages does the aluminum die-cast basket offer with the Hifonics Colossus CX15D2?

The aluminum die-cast basket of the Colossus CX15D2 offers several advantages, including high stability and excellent heat dissipation. The cast material allows the subwoofer to effectively resist vibrations, producing a clearer sound. It also provides resistance to deformation under pressure, an important aspect when used in the SPL range. The thermal properties help manage the high temperature peaks of up to 220° C generated by the dual voice coils. Thus, performance is maintained even under maximum continuous operation without compromising the construction.

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.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
