Help with figuring this out

[oxsign 5,000+ posts]

I need to find out what the correct airspace is with this box. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

I know it's kinda crazy, but I need to maximize the room I have for an 18" sub I have coming in shortly. Thx for your help, Vic. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thats good then. I need to get at least 5cubes. I plan on running it ported with 2 6" aroe ports tuned to 34hz powered with an Orion 2500d. //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif

It's about 800-1200 rms. At 2ohms the 2500 will do about 1800. So I'll just have to keep the gains low. I was more concerned with giving the sub the proper space. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Those little end pieces were giving me a little trouble though. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Don't forget that wood has a thickness //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

 

[jcbabb 10+ year member]

Yeah, that's gross...

He did not say what thickness of wood nor how many layers. Can't do it all //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The dementions given are single layers. I will put a 2nd top layer on as well. It also will be .75" MDF. Sub displacment will be .4, and i'm not to sure what the ports (2 6" areos) & braces (1" dowls) will be. Thx for the help guys. Those pieces over the wheel wells are throwing me off. I only came up with 5.581 cubes. //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif
