[QUOTE="Troponin, post: 8539353, member: 671853"] I assumed these two subs would have the same recommendations, but looking at the CAB website and then looking at the SA website, they are slightly different. To make it more interesting, the CAB website doesn't have as many details as the SA site. I am going to be having the local shop custom make me a box for this. They carry SA, so I am sure they are familiar with building enclosures for them, but I wanted to make sure I have the info and knowledge needed if they ask me questions about the Ultra. According to SA site, the recommendations are... Sealed 1.0 ft^3 Ported 1.5-2.0 ft^3 @ 35hz Displacement 0.14 ft^3 Depth 6 1/2" Outside Diameter 12 5/8" Cut-Out 11 1/8" Cab site just has this... 2ft^3 ported 12-18in^2 of port per ft^3 Tuned to 35hz I remember reading that folks were using their SA enclosures for their Ultras and they were actually louder with the same enclosure. Based on the above and that feedback, can I Just tell these guys to build a box to the same specs as the SA if they are unsure? They appear to be the same, but this isn't something I want to mess up.
