Titanium range 6" Woofer with 3" voicecoil, 8Ω. Hybrid magnet.
The Morel TiW 638Nd Woofer is a highly advanced bass-midrange drive unit featuring many class leading innovations such as the Uniflow™ Aluminium diecast chassis (designed for maximum undisturbed airflow with minimal rear reflection) and the unique Hybrid™ Neodymium / Ferrite mixed magnet assembly. In common with all Morel drive units, the motor system is superbly engineered featuring a Titanium voice coil bobbin and a large 3" voice coil wound with Hexatech™ Aluminum wire. Hexatech wire has an hexagonal cross section thereby eliminating the air gaps usually found in voice coils.
The frequency response is very well controlled to 4Khz with good off- axis characteristics. Power rating is 150w nominal and can withstand short term peaks of 1000 watts. A full datasheet can be downloaded from the bottom of this page.
