Description
Discover the TiW 634Nd from Morel, a high-quality 6.5" (16.5cm) bass-midrange driver from the Titanium Advanced series. This speaker features an open uniflow die-cast aluminum chassis that reduces reflections and a hybrid neodymium/ferrite magnet system. The 3" Hexatech aluminum voice coil on a titanium body ensures low energy storage and guarantees a high power handling of up to 1,000 watts. With a sensitivity of 88 dB and a frequency response of 40 to 4,500 Hz, the TiW 634Nd offers a clear sound experience. Ideal for a wide range of enclosure options, this bass-midrange driver impresses with its flexibility of use.
Highlights
- Open Uniflow die-cast aluminum chassis for reduced reflections
- Hybrid neodymium/ferrite magnet system with ferrites
- Titanium coilformers for low energy storage
- 3" Hexatech aluminum voice coil
- High instantaneous load capacity of 1,000 W
Morel Titanium Advanced Series
Morel's Titanium Advanced Woofer Series is the latest leap forward in woofer design. Huge 3" Hexatech™ aluminum voice coils (using hexagonal wires for high sensitivity and power handling) are wound on titanium bodies for amazingly low energy storage, resulting in lightning fast transients for superior transient response 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™ die-cast aluminum housing
All this would mean nothing if the air sucked in by the speaker got stuck in the engine or frame. Morel has designed the Uniflow chassis to be as open and sonically 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-sapping compression are virtually eliminated. The Uniflow chassis also allows the use of an oversized spider for complete control over the oversized voice coil.
The TiW 634Nd 6" woofer features a hybrid neodymium/ferrite magnet system, a 4-ohm impedance 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 of up to 1,000 watts when used correctly.
