Carbon fiber cone
The rigid carbon fiber cone gives the E150HE-44 a unique design while offering a number of performance advantages. With one of the highest strength-to-weight ratios of any material available, carbon fiber minimizes moving mass, allowing for extended low frequencies without sacrificing efficiency. The woven diaphragm has excellent damping properties that control unwanted resonances for a smooth response up to 4000Hz. The optimized profiles of this diaphragm and the dust cap ensure that there is no distortion when exposed to high stresses, so that smooth response and low distortion remain constant, even at high output levels. Finally, the outer edge of the cone has been reinforced to better control cone breakup and help maintain a controlled off-axis dispersion.
