The SCM 634 from Morel, a 6.5 (16.5 cm) woofer, impresses with technical precision and impressive performance. The unique construction with a sandwich cone of carbon fiber/Rohacell/carbon fiber ensures impressive rigidity and responsiveness. The 3 Hexatech™ aluminum voice coil, combined with the copper sleeve for reduced inductance, minimizes distortion and maximizes sonic accuracy. With a power handling of 300 watts, this midwoofer can withstand high volumes, while the 4-ohm impedance enables efficient driving. Benefit from the Masori Low Price Guarantee and secure the best car hi-fi quality at an unbeatable price.

Power and precision: 300 watts power handling

The SCM 634's high power handling of 300 watts ensures reliable performance even under the most intensive use. This value is ideal for users who demand deep and powerful bass without compromise. Power handling plays a crucial role in preventing overload and ensuring consistent sound quality even at maximum output. Compared to other models in the car hi-fi market, the SCM 634 stands out with its exceptional power handling, which supports an extended dynamic range.

Optimal impedance at 4 ohms for a wide range of applications

With an impedance of 4 ohms, the Morel SCM 634 ensures universal compatibility with numerous amplifiers. This impedance is common in the car hi-fi industry and allows the midwoofer to be used in both standard and custom setups. A higher impedance would limit the speaker to more specific amplifier setups, while a lower impedance would require a greater load on the amplifier outputs. Thus, the 4 ohm impedance offers a perfect balance between power efficiency and adaptability.

Frequency response from 40 to 5,000 Hz for clear detail reproduction

The frequency response of the SCM 634 extends from 40 to 5,000 Hz, ensuring comprehensive audio reproduction. This midwoofer excels, particularly in the bass range, with its clearly defined and powerful performance. This frequency range ensures seamless and harmonious transitions to the tweeters, creating a balanced sound. A wider frequency response would provide even more comprehensive coverage, but at the expense of the specialized bass performance that the SCM 634 masterfully delivers.

Hexatech™ aluminum voice coil: technological highlight

The 3 Hexatech™ aluminum voice coil utilizes unique Hexatech technology to save weight while maximizing rigidity. The aluminum construction reduces the overall mass of the voice coil, enabling faster motion response and lower distortion at high frequencies. A heavier coil could compromise response speed and precision. The SCM 634 voice coil is designed to allow precise control over the diaphragm movements, thus expanding the dynamic range of the speaker.

Sandwich membrane material for excellent sound performance

The SCM 634's carbon fiber/Rohacell/carbon fiber sandwich cone ensures strength and lightness. This combination results in a cone structure that efficiently controls vibrations and minimizes resonance, resulting in clear sound reproduction. The use of this material combination ensures that the midwoofer remains stable even at high volumes. Using other materials, such as paper, could result in unwanted drone and distortion, which are effectively avoided with the current cone configuration.

High sensitivity of 89 dB for superior efficiency

With a sensitivity of 89 dB, the Morel SCM 634 is designed to achieve high volume even with low amplifier power. This means the midwoofer requires less power to achieve a comparable volume compared to speakers with lower sensitivity.
