[QUOTE="Oraclem19, post: 8130838, member: 652985"] curious to build one of these, from what you say(some of the time) it is simple calculate rear chamber tune, multiply ratio for front chamber, port front chamber. Yet with all the redesign, what is there to adjust so many times? ratio, port volume, and port size? Just looking to get enough information to not put $800 into wood redesigning this many times. Possibly how to find what Fb to tune front chamber to and how that(as well as Fc) translate to the response range? Not sure if you have a preferred program or if there is one. Used to use Bassbox until my license expired. Possible in Hornresp? Not exactly trying to rule 4th orders, just trying to get Q requirements for a good 4th order woofer, and be able to make 35-55 flat(ish) response boxes. Anything on that is just a bonus. [/QUOTE]
