[QUOTE="bbeljefe, post: 8283609, member: 655960"] Generally speaking, one of the most important specs to look at when deciding whether a sub will work for your application is EPB or, efficiency bandwidth product. It's derived from dividing the driver's Fs by its Qes and it works as a guide for enclosure alignment.... Drivers with: 0-50 EBP will work best in sealed or 4th order alignments and they require larger boxes. 51-80 EBP will work well in sealed & 4th order or vented & 6th order enclosures and will work in a variety of box sizes. 81-110 EBP will work best in vented & 6th order enclosures and in small enclosures. 110-↑ EBP are typically hard to model and tend to defy the above rules of thumb. Adding to that, if you put a low EBP sub in a small box you're going to kill it's low end response and if you put a high EBP sub in a large box, you'll kill its power handling. Of course, all of this is general and there are exceptions so, it's really important to do some extensive reading if you want to better understand how this and other specifications work. [/QUOTE]
