I need to build a ported enclosure for an 18 inch subwoofer. Help?

I don’t know right off – but I hope this helps.

@JeanPaulSartre Thanks, but I found that calc also… It doesn’t help much :/ I think I am just going to wing it and hope for the best. THANK YOU ANYWAY!!!!!!!!!!!!!

@pikipupiba I did basically that for a smaller 12” enclosure – went overkill at first with a port, and later shrank it down and took the port off – worked great both ways. lots of MDF and caulking lol.

@pikipupiba Don’t forget to write back here with results. I for one would be interested to hear how it works out.

OMG THIS IS ONE OF THE GREATEST SUBWOOFERS I HAVE EVER HAD THE OPPORTUNITY TO LISTEN TO!!!!!

Ok, here is how it went down… I completely wung it and it totally worked out. This beast shakes my entire frat house (3 stories tall). The party went AMAZINGLY!!!!!!!!! (except that I blew up my brand new 3000 Watt amp :( ) I will post links to pictures as soon as I upload them!!! Thank you all for all of your help!!!!!!!!!!!

Congrats! Good job!

Woo hoo! I’m glad it worked out!
