Deep bass and throws far. I've dealt with many different boxes with some breaking apart. Sp10 is by far the best one, sound and quality. Makes my single ten sound fantastic, with rap music and talk radio. Lol. Tuned deeper than a single 15 skar box. 2 thumbs up.
Built very well, Tuned deep. Hammers with a Hertz MP250 sub.
Fox Aoustics knows their stuff! Boxes are built with specs on the box so no guessing! The sound quality is on point! Will not shop anyplace else for a sub box! I love mine.. love my first two so much I ordered a 3rd!! I live in Michigan.. I Almost thought I ordered through Amazon because the shipping was so fast! 😂🙌🏾
