[QUOTE="RAM_Designs, post: 6587737, member: 566575"] Here is the OP from roe: "need a favor whats this tuned to [URL="http://img36.imageshack.us/img36/8986/ported12v2.png"]http://img36.imageshack.us/img36/8986/ported12v2.png[/URL] port is 27" long total volume is 3.75 volume after port is 2.6" He's telling you that the net volume is 2.6ft^3, and that the port is 27" long. I don't know why you're arguing the point of 3.16ft^3 tuned to 37.5hz. It's not the question he was asking. What he wanted to know what it was tuned to. You responded at roe with 28.XXhz, which is incorrect. Port length was already given to you(so I don't know why you're bringing up the 16.5" or whatever port length), but you plugged in 3.75ft^3 into the port calcs instead of 2.6ft^3. You are doing it wrong, plain and simple. You are not doing it the same way as me, just in a different order. You are not putting the net volume into the port calculators, which is why you came up with 28hz when you used 3.75ft^3 instead of 35hz when using 2.6ft^3 for the net volume. Stop defending your method, it is simply wrong and not all that accurate(as you can see in this case it is nearly 7hz off when using gross volume instead of net volume). You can not start off with gross volume, plain and simple. Gross volume is NEVER used in the port length calculations. I don't know how else to put it. [/QUOTE]
