Sorry about the HSU I though you might have some wiggle room. Now for the SVS cylinder sub it takes up less floor space and it has the same specs as their PB12-NSD which is a box sub as far as matching up with your setup it will. SVS is well respected in this forum along with HSU . I own the PC12-NSD but before I did I was looking at these 2 subs as well. Went with SVS because of the floor space issue. There are not many box-style subs that are on the same level as this sub,there are a few from companies such as HSU,Outlaw,Sunfire and Epik.
