Morel Technology Explained
Innovative technology and a distinct design are at the heart of Morel’s R&D philosophy. Our expansive know-how and total control over the entire design and manufacturing process, allowed us to develop products that effectively overcome the acoustic challenges of car audio and deliver the most innovative and best natural sounding speakers.
The following are some of the iconic technological traits that
have become the foundation of Morel speaker designs.
Made from 100% aluminium wire shaped like a honeycomb, the HexatechTM voice coil reduces air gaps in the coil windings, thereby increasing efficiency by up to 20%. Being lightweight, HexatechTM voice coils are largely responsible for the extraordinary fast transient response Morel drive units are known for.
The new Morel grille has a specific pattern of holes in different shapes and diameters engineered to minimise the “horn” effect (high frequency peak caused by the resonant frequency of multiple same-size holes). Innovative metal processing enabled the construction of a very thin nearly transparent grille that hardly affects the sound at all frequencies whilst maintaining structural integrity to protect the drivers. The Lotus grille is a registered design protecting Morel’s intellectual property.
The bobbin material has influence on the acoustical parameters of the driver, its power handling and the reproduced sound quality. By using titanium bobbin, Morel intended to raise the Mechanical Factor (QMS) in order to enable a wider selection of enclosure types and sizes. As for the sound quality, one is able to discern a distinctively “crisper” sound when compared to an equivalent driver with aluminium bobbin. The rigid characteristic of titanium, along with its other advantages produce a driver that is tonally balanced and accurate, with exceptionally fast transient response
Morel speakers with EVC™ technology utilise voice coils that are up to three times larger than those used in conventional loudspeakers. The EVC™ design moves the magnetic drive system to within the voice coil, eliminating stray magnetic flux by effectively directing all the magnetic energy to the voice coil. The result is an ultra-efficient and powerful design that is highly compact with efficient heat dissipation and reduced cone breakup for lower distortion.
An under-hung voice coil features a voice coil winding height shorter than the magnetic gap. This means the voice coil is positioned within the magnetic energy field at all times leading to greater articulation and transient response.
The modern car environment is highly sensitive to stray magnetic fields. Vehicles now use several computer control devices throughout the car, and conventional non-shielded speakers can be a threat to the vehicle’s electrical integrity. Morel speakers featuring the company’s EVC™ technology are more than 90% shielded—safe for installation in today’s high-tech vehicles.
Morel’s double drive system generates more magnetic energy than a single magnet of similar size, increasing efficiency and the dynamic range. The position of the secondary magnet fixed above the top plate in the motor is the key in controlling stray magnetic flux, thus generating a more focused magnetic field while also contributing to the “shielded” characteristic of our speakers.
A low resonance frequency of the tweeter is critical in order to achieve a low crossover point, flat frequency response, and a natural sound reproduction. The highly damped integrated rear chamber (IRC) was designed to decompress the air modulation behind the tweeter diaphragm.
A specially engineered damping compound applied to the soft domes of specific Morel tweeters and midranges. The combination of these materials creates a diaphragm that exhibits controlled cancelling break up (accurate–flexing), meaning each break-up mode is counteracted by another in the opposite direction. This cancellation of break-up modes leaves nothing but the pure, natural sound Morel tweeters and midrange are famous for.
Uses an open design that is aerodynamically efficient, allowing air and sound waves to flow uniformly and smoothly. Its geometric shape also eliminates interference with the woofer’s moving components, enabling the use of a low-profile spider for greater support and stability.
By using a vented pole piece behind the diaphragm, the rear sound waves travel down the pole piece vent and into an enclosure that is behind the magnet. The rear sound waves are largely absorbed by the materials inside the rear enclosure and do not reflect back out the front of the diaphragm. Thereby lowering distortion and improving the frequency response.
Well-designed gold plated terminals to ensure high level conductivity between lead wires and speaker cables.
Also named shorting ring and has several clear benefits:
1. Reduces impedance rise and increases sensitivity.
2. Reduces voice coil inductance, which minimises non-linearity during operation.
3. Improves overall speaker performance across the frequency band.
Morel’s experience in motor design has allowed it to harness the magnetic energy in extremely effective manners. Typically the bigger the magnet the more energy however; in automobiles, there is often not the space for physically large magnets. Morel offers a number of solutions to deal with this problem.
Ferrite magnets are the most commonly used in speakers. While they look similar, there are several grades of magnets. Morel uses only the highest intensity available in its designs. As a result, Morel’s magnetic systems are highly compact yet deliver more magnetic flux than conventional ferrite magnets.
The most powerful magnet available, neodymium enables Morel to create physically compact speakers, such as tweeters and midrange, that fit in very limited spaces without limiting the quality of sound.
Morel’s double ferrite drive system generates more magnetic energy than a single magnet of similar size, increasing efficiency and the dynamic range. The position of the secondary magnet fixed above the top plate in the motor is the key in controlling stray magnetic flux, thus generating a more focused magnetic field while also contributing to the “shielded” characteristic of our speakers.
Most speaker cones are constructed from two elements- dust cup and diaphragm. Using unified construction increases the structural integrity and strength of the cone, making it less susceptible to cone break up and unwanted distortion
