[QUOTE="bbeljefe, post: 8159153, member: 655960"] The Sundown will do well in a sealed box and, a small one at that. The others might as well but I've not looked at them so I can't say for sure. But to help you in your search I'll give you a piece of information that will allow you to do your due diligence with some level of confidence. There is a parameter called Efficiency Bandwidth Product (EBP) that will give you an idea of what kind of box a sub will work in. To get this number, since manufacturers aren't usually forthcoming with it... you divide the driver's Fs (or Fo) by its Qes. For the Sundown, the EBP is 58.12. Here's how to use that number... 1-50 sub is best suited for sealed or 4th order bandpass enclosures 51-100 sub is suited for either sealed or ported enclosures of any alignment 100+ sub is best suited for ported or 6th, 8th order enclosures Personally, I have found that drivers above 70 do not perform well at all in sealed boxes and those that are at or near (50-55) do not perform well in ported boxes. Of course, there are exceptions and this is only a rule of thumb but it is a useful tool to help you cull drivers from a long list. All that aside, you have about 2.3 cubic feet to work with and ported boxes sound much better than sealed if they are constructed properly. You mentioned not having the tools to build a ported box but, if you have the tools and the skills to build a sealed box, then you can build a ported box also. Slot ports work well and you don't need any more specialized a tool to cut a slot port than you do to cut any other square panel. Even if you don't have a router to round off the ends of a port, you will still see a benefit from a ported box over a sealed. And no... ported boxes are good for any kind of music, if they are built to fit the driver that's in them. My personal taste in music is hard rock/metal and I haven't had a sealed box in my own vehicle since 1986. Lastly, the SA series from Sundown has a low compliance, meaning they have a stiff suspension. What this means in the box world is that those drivers will still play tight, fast bass notes in ported boxes because they do not need the acoustical suspension of a sealed box to keep them in check.
