i think you forgot to take in to affect the .75 wood thickness of the port instead of a 2 inch opening like the calculator says it would be 2.75 x 13x22 which would make the box 2.27953125 cubic feet with the displacement of port .455 and sub of .16 and the box inside dimensions of 28.5x13.5 x 13 =/1728 = 2.89453125 before displacements. sorry did not calculate the port tune yet . When a port bends you can't figure the area the port takes up separately then subtract it from the box volume. For example the way the calculator I set up figures internal volume is it calulates the volume of the green area then the volume of the orange area depending on the length of the pink board. Then it adds them together and subtracts any displacements you might have.

I got 2.33ft^3 @ ~34hz after all displacements.

I've seen thier slick series at a local shop, I didnt ask about them cause I dont care for hearing the sales regurgitation pitch. They look nice in person though.

The can of spaghetti O's wasn't bulging was it?

I thought that was the volume and tunning also until i looked at the link to the picture and noticed the 14" port was the length to the back port wall. hmmm interesting i thought the displacement of the RE Audio Sx 10 version was .15 cubic ft what program are u using to enter the dimesions It is. There is a flaw in RE's program somewhere that throws it off. I have a spreadsheet I set up that calculates it for me.

JL Audio - Car Audio Systems I've entered the formulas into a spreadsheet so it is easier and quicker also.

Where are you getting these numbers from? The sub's displacement is .18 ft^3 which would bring the total to 2.445 ft^3. I did the math. I wouldn't trust RE's calculator.

I miss the Mystery Science Theater 3000.

I don't care for that calculator at all. Using all your input I got those dimensions at [email protected] after sub displacement.

Looks like it is tuned to high. After sub displacement I got the enclosure at 2.38ft^3 @ ~36hz.

There isn't really any shows in Michigan. There is one in July at the Taylor Gibralter but I haven't seen a date for it yet. Then I've seen some advertised for the U.P. but haven't gone to those. There might be some small shows that aren't sanctioned. DBDrag event locator. Event Locator MECA event locator. http://mecacaraudio.com/eventtable.aspx

Just something I put there to tell me how long the port needed to be to get to that point in the enclosure.

30.01Hz that is with end correction(virtual port length). 30.63 is the tuning of the physical port length. Yes, Merry New Year.

Ever thought about distributing it at a fee anytime in the future? (just curious) No, not really. It has some glitches in it that need to be watched, I can fix the glitches but its something that I know is there and I rarely run into it so I never took the time to add to the formulas.

Well not a problem at all I understand, Im gonna need for you to do a little more work and I will be done. Can we change the max dimensions depth to 20"D and lower the tuning close to 30Hz (30-30.5hz) and volume after displacement 3.6-3.8ft^3. Thanks and I promise Im stuck with these numbers I just posted. It is no problem, if you really wanted to I could do a design in sketch up and throw 45's in it and everything. But that would eat up your internal volume pretty quick.

Its an excel spreadsheet I made, sorry not for distribution.
