[QUOTE="danfortner, post: 343461, member: 547595"] Thanks, I am going to be getting 1/2 plexiglass, which is actually stronger than 3/4 mdf. But about the box size, I originally thought that my box was going to be 2.0cuft. Because I really want this to sound very similar to my sealed box, just louder, I am trying to keep the Qtc close to .7070 . Using the equations on diysubwoofers it says that a 2.0 cuft box would have a qtc of about .49 . I actually don't know all that much about Qtc, but I assume that is too far off to be good. If you have another calculator that suggests cuft based on a sub's thiel small parameters, please tell me, or if you have personal experiance with eclipse titaniums, let me know. It is just that these subs excell in smaller than normal sealed enclosures and I think that makes their ported boxes also farily small. Help me out if you can though, I am still torn on the box size I will make. All I have to do is decide that, and then I can construct. [/QUOTE]
