I cleared up a misconception I had and figured others may have that misconception so I posted about it. Don't act like I'm stupid. I'm not. Box designs I've made since then have been perfectly fine. No need to bash people on here. I understand that. But when an experienced designer and builder can easily see that you don’t know what you are doing when it comes to figuring an enclosure design because you obviously don’t know how to calculate using t/s parameters then he is gonna call you out if you offer to help somebody or if somebody asks for your help. I would be wrong if I didn’t. I can see that you do know some things concerning designing and building enclosures, but you don’t know how to calculate t/s parameters nor figure in other basic to intermediate aspects of building an enclosure that even calculations can’t do. How can somebody truly teach (design) if they barely have learned? Just because you can build and design an enclosure on a super flawed program and then that enclosure makes bass that you and other people, who aren’t professionals, perceive as good bass, means nothing. I’m not bashing you, dude. Yeah, you are learning and are on a good path, but you aren’t ready to design enclosures for people who come to a world renown forum to have done. You should be on here and other forums learning. I liked you when I first seen the title of your first post and then read the meaning of your screen name. So, I’m not bashing you or hating on you by any means. If I let you design an enclosure that somebody wants and not tell them that you aren’t a professional, almost the complete opposite, then I would be a bad person. Kinda like if I let my homeboy have sex with a girl that had the clap and didn’t tell him even though I knew it.

And if you make the enclosure bigger with the same port area then the port length has to be less to yield the same port tuning frequency. That calculator is basically on point, it’s only off by a hundredth of a point. Let me post some links that would help whoever that wants to design subwoofer enclosures. https://www.the12volt.com/caraudio/boxcalcs.asphttp://www.mh-audio.nl/Calculators/PortAirspeed.html http://www.psp-inc.com/tools2.html http://www.mh-audio.nl/Calculators/Bandpass.html “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
SNYPER Posted March 19, 2021 Author Report Share Posted March 19, 2021 So I’ve finally got the time and space to build my box @1point21gigawatts are you saying my port is wrong because the rear port walls are longer than half of my center port walls?

How’d you splatter that black paint and what type of clear did you use? “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
SNYPER Posted April 12, 2021 Author Report Share Posted April 12, 2021 Kinda did a bootleg bowling ball, base coat with metallic silver, spray plastic bag with black paint and blot it, candy wine red over and clear, it’s a motorcycle kit from thecoatingsstore, was cheapest way to go as a kit Link to comment Share on other sites More sharing options...
