Discover the TiW 638Nd from Morel, a 6.5-inch midwoofer that impresses with innovative technologies. Equipped with an open Uniflow aluminum die-cast chassis, it minimizes reflections and offers optimal sound quality. Its hybrid neodymium/ferrite magnet system, combined with a titanium body for the voice coil, ensures low energy storage and fast transients. With a power handling of up to 1,000 watts and a frequency response of 40 to 4,500 Hz (on axis), it is ideal for a wide range of sound requirements. Adaptable thanks to its 8-ohm impedance, this midwoofer is part of the renowned Titanium Advanced Series and offers exceptional sound comfort.

Morel Titanium Advanced Series

The Titanium Advanced Woofer Series from Morel is the latest leap forward in woofer design. Huge 3" Hexatech™ aluminum voice coils (which use hexagonal wires for high sensitivity and power handling) are wound on titanium bodies to enable amazingly low energy storage, resulting in lightning-fast transients for superior attack and decay. The Qms value has also been increased, allowing for a wider range of enclosure options. Three magnet systems are available: Dual-Ferrite, Hybrid™ Neodymium/Ferrite, and Hybrid™ Neodymium/Ferrite with a Coppersleeve Neolin™ motor. Each system is available with an impedance of 4 and 8 ohms.

Uniflow™ aluminum die-cast housing

All this would mean nothing if the air drawn in by the speaker got stuck in the motor or the frame. Morel has designed the Uniflow chassis to be as open and acoustically transparent as possible. An oversized ventilation opening on the pole cap, a spider suspended from the frame, and an exposed voice coil ensure that reflections and power-robbing compression are virtually eliminated. The Uniflow chassis also allows the use of an oversized spider for full control over the oversized voice coil.

The 6" TiW 638Nd woofer features a hybrid neodymium/ferrite magnet system, an impedance of 8 ohms, and a unique one-piece DPC (Damped Polymer Composite) cone that offers a flat frequency response from 40 Hz to 4,500 Hz on-axis and from 40 Hz to 4,000 Hz off-axis. Thanks to its large voice coil, it can handle 10 ms peak power transients up to 1,000 watts when properly applied.
