    Prefab 4-12 box

    Posted by Mike B on Sep 27, 2021

    JP was right! This is a quality box and gets low! I am running Skar audio ddx 12s in it powered by a sundown sfb3000d and it hits hard!

    This box is very well built and tuned just right! Just about the perfect size for the DBSA 252 Deaf Bonce 12's and sounds amazing. Do yourself a favor and buy this box!
