12-23-2005, 11:25 AM
Hey guys, I'm gonna start building my box for my SX 18 tonight. Around 12 I'll probaby run up to Lowes and get the wood I just need to get a hold of one of my friends with a truck lol. Heres the specs I have on the box, let me know if there is anything that doesn't look right.

Box Dimensions-12.6875in H x 38in W x 38in D= 8.625ft^3
Port Dimensions- 6.5ft^3 tuned to 32 Hz
11.1875 x 9= 100.7in^2 of port area and 32.25in D
Displacement= 1.88 ft^3 + Sub Disp(.22) = 2.1ft^3
Total= 8.625ft^3-2.1ft^3= 6.53 ft^3

You can round those measurements to increments of .25 and it will be a little easier on you Im sure.

Yeah I did that when I made the plans, the only problem I found was that I didn't account for the displacement of the wall of the port, but I just made the box a tad longer and it should be fine. I made the base and walls, tried a test fit in the trunk. Doesn't fit, removed all of the carpet and padding and now it does. The big problem is that it won't fit in with the sub in, so I have to flush mount the sub and loose a little more air space. Oh well, thats what I get for buying an 18 lol.:)

How you like your sx 18 and how much power are you giving it?
