High Qts, good for sealed box. Some sample boxes below.

Using a proprietary paper blend cone made in-house this woofer delivers good mid/bass response, 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 ensure quality control. This makes this a good “bang for the buck” full range driver.

• Proprietary cone material with natural fibers made in-house
• Light weight foam surround
