    So cool! Quality All the way down to 18hz
  

*by A***N on Reviewed in the United States on March 26, 2020*

They certainly don’t make them like this anymore! Aluminum cone, dual spider, dual voice coil, polished flared vented pole piece make this an incredible piece of engineering that; should be brought back because it’s so awesome!
