The TiCW 638Nd from Morel is a 6.5 inch midwoofer from the Titanium Advanced Series, equipped with a unique hybrid neodymium/ferrite magnet system. It offers an impressive power handling of up to 1,000 watts and stands out with an open Uniflow aluminum die-cast chassis to reduce reflections. The 3" Hexatech aluminum voice coil combined with a titanium body ensures low energy storage and enables lightning-fast transients. With a frequency response of 40 Hz to 4,500 Hz on-axis, this midwoofer delivers impressive sound quality and versatility. The combination of state-of-the-art technology and selected materials makes the TiCW 638Nd an outstanding choice for demanding audio projects.

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 allow for amazingly low energy storage, resulting in lightning-fast transients for superior attack and decay performance. 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 of this would mean nothing if the air drawn in by the speaker got trapped in the motor or the frame. Morel has designed the Uniflow chassis to be as open and sonically transparent as possible. An oversized vent at 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 complete control over the oversized voice coil.

The 6-inch TiCW 638Nd woofer features a hybrid neodymium/ferrite magnet system, a coppersleeve Neolin motor (for optimal transient response), an impedance of 4 ohms, and a unique one-piece DPC (Damped Polymer Composite) cone that provides 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.
