Frequently Asked Questions about Rampage 18

What power does the B2 Audio RAMPAGE Series 18 offer?

The B2 Audio RAMPAGE Series 18 Subwoofer impresses with its remarkable performance. With a power handling of 5000 W RMS, it can deliver consistently high output without overheating. The maximum power reaches an astonishing 10,000 W, making it ideal for intense audio applications. These performance specifications are crucial for providing a deep, powerful sound experience, especially appreciated in demanding environments, such as car audio competitions. The combination of high RMS and maximum power ensures an unparalleled sound characteristic that effortlessly reproduces powerful bass lines.

What are the dimensions of the B2 Audio RAMPAGE Series 18 Subwoofer?

The B2 Audio RAMPAGE Series 18 is a massive subwoofer with a nominal diameter of 18 inches (468 mm), requiring ample space for powerful bass reproduction. The mounting depth is 12.67 inches (322 mm), while the cutout diameter is 16.73 inches (425 mm). This allows for stable integration into common enclosures and ensures efficient sound pressure development. The overall diameter of 468 mm guarantees a sufficiently large diaphragm area for strong bass. Overall, the B2 Audio RAMPAGE Series 18 is designed to perform optimally both acoustically and structurally.

How efficient is the B2 Audio RAMPAGE Series 18?

With a sensitivity of 94.5 dB, the B2 Audio RAMPAGE Series 18 is extremely efficient. This figure means that the subwoofer can generate a relatively high sound pressure even at low power. This makes it particularly suitable for use in systems where volume and sound quality are essential. A high sensitivity level also ensures that even with lower amplifier output, a voluminous, precise bass can be achieved. Especially when combined with powerful amplifiers, the subwoofer can unleash its full potential and produce immense sound pressure levels.

What materials were used for the B2 Audio RAMPAGE Series 18?

The B2 Audio RAMPAGE Series 18 Subwoofer uses high-quality materials for improved performance and durability. The voice coil is made of premium 8-layer aluminum with a diameter of 4 inches (101.6 mm), which ensures efficient heat dissipation and increases mechanical load capacity. The diaphragm is made of carbon fiber, a material known for its lightness and stiffness, minimizing distortion and enabling accurate reproduction of low frequencies. The TWS surround is made of highly dampening foam, ensuring even and wide dispersion to achieve the best possible sound characteristics.

How powerful is the magnet of the B2 Audio RAMPAGE Series 18?

The B2 Audio RAMPAGE Series 18 is equipped with a ferrite magnet that has an impressive weight of 1400 oz. Such a large magnet provides a strong magnetic field strength, which is essential for the precision and power of the Subwoofer. This feature is particularly crucial when reproducing deep and powerful bass, as the diaphragm must respond quickly and accurately to electrical signals. This ensures a clean sound that remains detailed and clear even at high volumes, a significant advantage for music lovers and audiophiles.

What frequency range does the B2 Audio RAMPAGE Series 18 operate in?

The frequency response of the B2 Audio RAMPAGE Series 18 ranges from 10 Hz to 500 Hz. This offers an outstanding bandwidth for reproducing low-frequency sounds and fully covers the central bass range. The deep frequency range allows the Subwoofer to reproduce even the lowest bass notes used in music production or cinematic effects. The upper limit of 500 Hz ensures that the Subwoofer can be seamlessly integrated into a speaker system by taking over the lower frequencies while the mids and highs are handled by other speaker units.

What is the resonance frequency of the B2 Audio RAMPAGE Series 18?

The B2 Audio RAMPAGE Series 18 has a resonance frequency of 27.2 Hz. This frequency describes the point at which the Subwoofer begins to vibrate on its own, without external frequencies influencing it. A low resonance frequency is advantageous as it indicates that the Subwoofer can reproduce deep bass much more efficiently and accurately. This is particularly important when reproducing infrasound, as the perceived sound fullness and pressure intensity are often crucial for the listening experience, especially in high-quality home and car audio systems.

What installation depth does the B2 Audio RAMPAGE Series 18 require?

The required installation depth for the B2 Audio RAMPAGE Series 18 is 12.67 inches (322 mm). This specification is crucial for planning the enclosure into which the Subwoofer will be integrated. Since the Subwoofer has a relatively large installation depth for its size, it is important to consider the available space in the vehicle or the associated speaker enclosure. Adhering to the correct installation depth ensures not only the mechanical safety of the speaker but also the acoustic performance, as the Subwoofer needs sufficient space for optimized sound radiation.

How does the surround affect the sound of the B2 Audio RAMPAGE Series 18?

The surround of the B2 Audio RAMPAGE Series 18 is made of a high and wide foam that directly influences the movement range of the diaphragm. This special foam surround allows the diaphragm to move efficiently and with great excursion, which is beneficial for producing low frequencies. The width and material of the surround are crucial for the stability and precision of the diaphragm movement, minimizing distortion and maximizing sound quality. A high-quality surround not only ensures the durability of the Subwoofer but also significantly contributes to the clarity and power of the bass.

What advantages does the carbon fiber diaphragm in the B2 Audio RAMPAGE Series 18 offer?

The carbon fiber diaphragm of the B2 Audio RAMPAGE Series 18 offers numerous advantages that benefit sound performance. Carbon fiber is known for its high stiffness while being lightweight, which means the diaphragm can move quickly and precisely. This is particularly important for reproducing deep bass and fast bass drum hits. The stiffness of carbon fiber efficiently reduces distortion and unwanted resonances, resulting in a clearer and more powerful sound. This material choice also allows for improved durability of the Subwoofer, as carbon fiber is resistant to material fatigue.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
