Morel Maximo Ultra MKII 603a - 3-Way Active Component Speakers

The Morel Maximo Ultra MKII 603a - 3-Way Active Component Speakers is the latest evolution in a long lineage carrying the Maximo name, bringing impressive sound quality at an affordable price to car audio enthusiasts. The updated component systems improve upon the already impressive sound of its predecessors, while cosmetic updates bring simple elegance to their appearance.

The Maximo Ultra MKII components are designed for easy installation in the factory locations of most vehicles with excellent off-axis dispersion, high resolution, and crisp detail to overcome some of the acoustic limitations of original speaker placement.

The 1-inch (25mm) soft dome tweeter and a 2.5-inch (51mm) midrange are both developed using Morel’s EVC technology for high-power handling, and naturally sounding response, and the 6.5″ woofers utilise large 1-inch diameter voice coils and high-grade ferrite magnet motors capable of excellent bass performance for that instantly recognizable warm Morel sound.

Regardless of what you drive or what genre you listen to, the high-value Maximo Ultra MKII will vastly enhance your listening experience.

Key Features

DMM Motor

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 focussed magnetic field while also contributing to the “shielded” characteristic of Morel's speakers.

EVC Motor

Morel speakers with EVC™ technology utilise voice coils that are up to three times larger than those used in conventional loudspeakers, enabling improved heat dissipation, power handling and linearity. The EVC™ design moves the magnetic motor system to within the voice coil, eliminating stray magnetic flux by effectively directing all the magnetic energy to the voice coil.

The EVC architecture is over 90% more efficient than conventional design, magnetically shielded, and highly compact.

Paper Cone

In use since the first loudspeakers, the paper continues to be an exceptional material of choice. Morel’s latest paper composite cones are ultra-lightweight, making them an exceptional pairing for drivers using smaller motors and voice coils.
