[QUOTE="1aespinoza, post: 8866870, member: 654802"] These are your max dimensions and they equal to 10.95 cubic feet. The 4 subs need 12 cubic feet for optimum performance. This is not even accounting for wood thickness, sub displacement, bracing volume, or port volume. djdilliodon! is a subwoofer builder so he knows how subs will perform based on the materials used to build them. 4 layer spiders are usually needed for high power subs to bring the cone back to center point without ripping off. 1500 watts will struggle with that stiffness hence the big box volume to make up for the lack of cone travel. Doxquzme suggested an isobaric setup. That was my thought as well when I saw the box volume requirements. Basically you build the box for two subs, mount two subs, then mount the other two on top of them face to face. You then wire the outer subs out of phase. This will help overcome the stiff spiders issue and need less power and box space for good performance. [/QUOTE]
