[QUOTE="THATpurpleKUSH, post: 8738940, member: 615398"] I am a supporter of competitions and I've been to MECA events, so in the interest of helping you and participation in the organization along with having a normal day off for once in a very long time, I had a few minutes to model your design to give you and idea of where you are starting at. Keep in mind models are not the end all be all of performance, this is simply a guideline and its for an XD15-44, the main difference is going to be the impedance plot because of the different coils, I didn't have a 2 ohm version XD in my database. I am including some quick screen shots as well as the pdf with all plots. Note that your design is very bottom heavy and some adjustments will need to be made, starting with ditching the severely undersized ports and stepping up to a proper size. The plus side to this design is that it will handle rated power down to about 27hz before xmax is reached and it begins to unload but it will be pretty boomy sounding at that point.
