The role of the Hexatech™ aluminum voice coil in the Morel EW 638

The Morel EW 638's 76.2 mm diameter Hexatech™ aluminum voice coil enables exceptional control and heat dissipation. This large diameter provides better linearity of the coil movement, which directly contributes to cleaner sound reproduction and a significant reduction in distortion. Aluminum is known for its excellent conductivity and, due to its weight, is ideal for use in voice coils, offering fast response times without energy loss. These performance advantages make the EW 638 the leading choice for audiophile sound installations that demand precision and clarity. Compared to products with smaller coils, the larger surface area of ​​the Morel EW 638 guarantees more stable performance, even at higher volumes.

Technology of DPC membrane material in the Morel EW 638

The Damped Polymer Composite (DPC) diaphragm material in the Morel EW 638 combines rigidity with low weight, ensuring pristine sound fidelity. This technology minimizes unwanted resonances and ensures a balanced soundstage. This balancing act between rigidity and damping results in a clear and precise sound that will delight even the most demanding listeners. This quality clearly sets the EW 638 apart from competing models, which often struggle with heavier materials and thus slower response times.

Effect of the Hybrid™ neodymium/ferrite magnet on the Morel EW 638

The Hybrid™ neodymium/ferrite magnet in the Morel EW 638 combines the strengths of neodymium—known for its extremely high field strength—with the durability and cost-effectiveness of ferrite. This fusion is no accident, but a deliberate decision to maximize magnetic force while minimizing material costs and weight. This gives the speaker the ability to reproduce richly detailed nuances in audio. A stronger magnet could further accelerate the movement of the diaphragm, but this would require structural reinforcement and increased weight, which is not always advantageous.

Resonance frequency and moving mass of the Morel EW 638 – Precise bass for every sound lover

Combined with a moving mass (Mms) of 16 g, this ensures excellent bass reproduction, lending the sound body depth and richness. This tuning is optimal for rich bass tones in dynamic tracks. A lower resonance frequency would benefit the lowest frequencies, but could lead to a weaker midrange reproduction if inadequately tuned. A comparable model could be less efficient with higher Mms, thus demonstrating Morel's sophisticated balance.
