    I use this Sub for my Home Dj setup and it ROCKS! It's actually well built and plays deep and smooth. The does not have a frequency adjustment only a gain knob but it's still a good buy. It's a true 18 and it plays low and clean without any distortion. I didn't hear any rattling or anything from the cabinet so I can tell it's built solid and probably has good internal bracing.

    Is there a padded cover made for the Kustom Kbx 18a to add protection to the cabinet when it's not being used or when the subwoofer is in transit?
