Box help for Xcon 18", Question about the ports

[basshead7890 10+ year member]

I'm wanting to know if I build a box like this and would it be ok with the ports like this. It would go in a 95 honda accord

9.67ft^3 gross, 7.34ft^3 after ports, after bracing somewhere between 7 and 6.5cubes after bracing, depends on if i invert it or not

thanks for any suggestions or comments

This is going to be a compression based design, so output should be great, as long as the design is done properly. What I mean by compression is, direct sound will be filtered, so it will be very low end output happy. If you calculated a response from it, check for a dip in the response above 60Hz, if one exists, it may be quite audible depending on the cabin acoustics. Compression ratio seems fairly appropriate but without figuring for anything myself, no actual answers can be given, only opinions. But interesting design. You might get away with more musical output by putting an angle in the bottom chamber area to break up resonances, that angles on the rear wall up, and realigning the ports to minimize compression between the side walls and the port, but if kept as is, I say its worth a build!

Just want to add that anything opinionated can be disproven, so never rely on opinions. I could be off just as much as anyone without calculating anything. But just letting you know how I feel. You did a great job on the design. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i came up with another design, & im leaning towards this now. Its a xcon18" & it would go in a 95 accord,

thanks for any comments/thoughts

I would use one of these for the port & i would try to cut it at 45degree angle and fiberglass the 2 ends together
