Choosing your subs
This box takes 8" subs only. The standard cutout is 7"; if your sub needs a different hole, the box can be cut to its actual diameter. Type the sub model in the "What Sub Model are you using?" box when you order so the box is cut to match, and the specs are looked up from the model if you are unsure. Xtreme Enclosures has not published the mounting depth, so call if your subs are deep. Shop 8" subwoofers.
Built to order
Built to order by Xtreme Enclosures from carpeted MDF wood. Estimated lead time: 20–40 business days.
