Product details

 

Using a cone proprietary paper blend cone made in house this woofer delivers good midd/bass response. Which is extended by the use of a optimized “whizzer” cone. This is supplemented by the use of a phase cone to better radiate the high frequency output. The paper blend cone is made in-house to insure quality control. This makes this a good “bang for the buck” full range driver.
