Como no puedo estar quieto, me voy a meter de lleno en unos monitores HUM de dos vias en caja cerrada.
Los drivers ya los tengo seleccionados, pero hay tres modelos que difieren muy poco entre ellos y no sé cual me irá mejor por sus características técnicas.

This is a new 5" design, an improved version of the classic MW142, which has always been highly-regarded with an enviable reputation.
Similar the older version, this new desing incoporates an extremely large diameter aluminium Hexatech voice coil for such a small unit.
The following improvements that have been made to the new product anhance the performance of the loudspeaker even more.
The chassis is a new type of particularly heavy pressed steel and is designed to allow the cone maximum freedom of movement, thanks to the addition of ventilation holes under th suspension.

This is one of the most popular woofers in Morel's range. Many manufacturers use it in 2-way and in multi-way high-end loudspeaker systems. Over the years minor improvments have been made to this woofer, the most significant improvement, its newly re-designed chassis, has now been introduced, resulting in this improved product.
The new chassis is of particularly heavy pressed steel is designed to allow the cone maximum freedom of movement, thanks to the addition of ventilation holes under the suspension. Morel's exclusive rear-vented, double magnet system stacked into the new chassis gives the product an interesting new look.
The loudspeaker's particularly large Hexatech aluminium voice coil supports a large area of tne cone, preventing cone break up and reducing high-power destortion.
The DPC cone and its center dome are one piece with a very shallow profile for better dispersion. This unit exhibits extraordinary reproduction of low frequencies, clear and warm mid-range and high power handling capability.

A new double magnet unit designed for 2-way and for multi-way high-quality system.
High power handling results from the large 3" Hexatech coil.
The magnet system is Morel's unique rear vented double magnet system, stacked into the new chassis. This chassis is of particularly heavy pressed steel and is designed to allow the cone maximum freedom of movement, thanks to the addition of ventilation holes under the suspension.
