This 6.5” premium woofer provides both value and performance. A custom fabricated woven carbon fiber cone allows for a rigid piston and fast transient response. A stylish yet sturdy round cast aluminum basket provides easy front mounting in an enclosure. The carefully designed aluminum phase plug eliminates the need for the additional mass of a dust cap and reduces lateral wave energy interference which causes unwanted peaks and dips in the frequency response. It is centered within inner and outer inductance modulating elements to reduce inductance.
