Ultimate 9" Subwoofer - 5.1" Voicecoil, 8Ω.
The Morel UW 958 is a dedicated 9" bass speaker of considerable power from the Ultimate Subwoofer range. This rugged drive unit features the Morel Uniflow™ Aluminium diecast chassis, a high flux double Ferrite magnet and a huge 5.1" / 130mm voice coil assembly wound with Hexatech Aluminium wire. The Accucenter™ self centering pulp fibre cone/cap is a one piece assembly offering high rigidity and excellent internal damping.
This drive unit features PFS™ Progression Field Symmetry: under extreme conditions, the spider and surround are engineered to act as progressive shock absorbers, preventing voice coil displacement and bottoming out - this improves voice coil linearity and maximum excursion.
The pole piece is vented (very large) for minimal compression under heavy drive conditions and power handling is very impressive at 500W nominal, 1500W short term peak. A full datasheet can be downloaded from the bottom of this page.
