This product is no longer what you see in the photo. Sonic is being supportive of the problem, but the manufacturer no longer makes the product like this and now the 2 cones are solid black, mounted onto the plexiglass with self tapping screws, and really pretty ugly.

Install was interesting since the box is sealed on the back, so connecting cables was rough, then it came with no screws for mounting anything, and the fiberglass didn't have proper predrilled holes for the screws, so they just kinda stick out instead of being able to drop flat with the fiberglass. The fiberglass cut wholes are also terribly tore up, like a poor drillbit was used that left ridged edges that are "covered up" like makeup on a zit with these black plastic cones.

I did get 3 years of warranty free for the problem, so I guess if I have problems I'll just use the warranty to get something that works.

I would consider this a bandpass, not a sealed as there are two chambers and one is ported. Compared to almost all other bandpass boxes I've heard, this one can produce higher frequencys but the overall clarity isn't as impressive. If I could do it over i would likely buy a q-logic enclosure instead.
