Your advantages with Masori

Maximum power of 300 watts and effective power of 100 watts: The ultimate B2 Audio Rage 8 CFM

The B2 Audio Rage 8 CFM offers an impressive maximum power of 300 watts and an RMS power of 100 watts. These power ratings determine the energy the speaker can handle without any loss of performance. A high maximum power is ideal for short-term power peaks without damaging the speaker, while the RMS power represents continuous operation. Compared to comparable models on the market, the B2 Audio Rage 8 CFM offers outstanding performance for its size, ensuring versatility and excelling in both traditional and high-end audio installations.

Frequency response from 60 Hz to 10 KHz: Precise sound reproduction with the B2 Audio Rage 8 CFM

The Rage 8 CFM's frequency response extends from 60 Hz to 10 kHz, covering a wide range of tones. This expanded sound spectrum ensures detailed sound fields and makes the speaker particularly well-suited for reproducing mid-bass and clear mid- and high-frequency frequencies. The ability to extend down to 60 Hz enables deep sound reproduction, making this speaker more attractive for music genres with powerful bass components. Compared to other 8-inch models, this frequency range represents a balanced balance between bass and mid-high sound output.

Sensitivity of 93.8 dB (2.83 V): Increased efficiency with the B2 Audio woofer

With a sensitivity of 93.8 dB at 2.83 V, the B2 Audio Rage 8 CFM offers excellent conversion efficiency from electrical power to acoustic sound waves. The higher the sensitivity, the less amplifier power is required to achieve a given volume. In this range, the speaker is more efficient than many competing products, significantly increasing sound production with the same amplifier power. This makes it an economical choice for systems with limited amplifier power.

Impedance of 3.3 ohms and its significance for the sound of the B2 Audio Rage 8 CFM

The Rage 8 CFM's 3.3 ohm impedance reflects the speaker's electrical resistance. This slightly lower impedance is ideal for parallel wiring with other speakers, making it an ideal choice for complex systems. Lower impedances can result in higher amplifier loads, but allow for higher power output per amplifier channel. Compared to standard 4-ohm speakers, this results in increased amplifier utilization, perfect for enthusiast audio installations.

Technical heart: 1.5 voice coil made of EICCW and 20 oz ferrite magnet in Rage 8 CFM

The use of a 1.5 EICCW voice coil combined with a 20 oz ferrite magnet in the Rage 8 CFM maximizes thermal handling and magnetic field strength. Coil material and magnet weight determine the thermal capability and efficiency of magnetic field generation, essential factors for the durable and award-winning sound. These components are significantly superior compared to competing woofers, positioning the speaker in its segment for quality and durability.

Resonance frequency of 78 Hz in the B2 Audio Rage 8 CFM: Defining the frequency range

The Rage 8 CFM's resonant frequency is 78 Hz, which corresponds to the natural frequency at which the speaker resonates most efficiently. At lower frequencies, this resonance supports special features in the mid-bass range, an advantage at these frequencies for maximizing volume and clarity in sound reproduction. In comparison, this is an advantage over models with less favorable resonant frequencies, as the speaker truly excels in the high-frequency pop genre.

Coated carbon fiber cone and double U-shaped Santoprene surround type for dynamic sound

Crucial components of the Rage 8 CFM's sonic character are the coated carbon fiber cone and the double U-shaped Santoprene surround. The carbon fiber coating ensures durability and crystal-clear sound reproduction. The unique U-shaped surround also increases stability at high volumes and ensures consistent movement. This combination results in an advanced sound profile and significantly exceeds the performance of typical cone materials.

Thiele-Small parameters of the B2 Audio Rage 8 CFM: classification and interpretation

The Thiele-Small parameters, a significant set of variables, comprehensively encapsulate the performance characteristics of the Rage 8 CFM. With an overall Qts of 1.05, the Rage 8 CFM stands out from the crowd, as a value beyond 1 typically indicates outstanding resonance capability. The mechanical Qms of 12.4 and the electrical Qes of 1.15 enable precise tuning and dynamic response, ideal for enthusiast car audio installations.

Installation and adjustment of the B2 Audio Rage 8 CFM with optimized dimensions: Maximizing installation efficiency

The dimensions of the B2 Audio Rage 8 CFM facilitate installation and compatibility: an overall diameter of 8 inches, a baffle cutout of 178 mm, and a mounting depth of 68 mm remain standard on the market and ensure flexible installation positions. This allows for seamless replacement of other components or expansion of the existing system. The net weight of 2.5 kg contributes to mobility and facilitates adjustments, making the speaker particularly attractive for professional car audio applications.

Versatility evaluated using the EBP value of 68.3 in the B2 Audio Rage 8 CFM

An EBP (Efficiency Bandwidth Product) value of 68.3 indicates that the Rage 8 CFM loudspeaker can perform equally well in sealed or vented enclosures. With this value, the loudspeaker is at the limit of what would be specified for a pure midrange tuning model, indicating the balance of bass and treble performance. This provides an excellent template for flexible system integration and demonstrates how this model is suitable for both sealed and bass-reflex systems, giving the installer a wider range of options.

The value of the BL factor of 4.9 and DC resistance Re of 3.3 Ohm in comparison

The B2 Audio Rage 8 CFM features a BL force factor of 4.9, which describes the productivity of the coil in conjunction with the magnets, and a DC resistance of 3.3 ohms. A higher BL provides greater control over movement, making the speaker more powerful and accurate in dynamic soundscapes. Compared to competing models, this value demonstrates its specific application in improving sound representation, resulting in a more detailed sound experience.
