thank you alton. you've clarified the situation completely. i am willing to learn, but it's hard to when everyone's just saying that was wrong, when it wasn't to me. i love to experiment and if that means i have to build 10 enclosures before i get it right, then so be it. i don't feel modeling software will deliver what i want as i can't hear it first hand. it just tells me that it's wrong or what have you. i like to experience first hand, and am not afraid to work and rebuild no matter what. i realize that software would make that job easier, and i would only have to tweak the small things in order to achieve my goal. i have observed many designs I've found in posts and what not where people have used software, and others have made suggestions until it was "right". therefore, i feel comfortable in the design that I've settled on, and am now just experimenting with the port length. i have read the specs for the sub that I'm getting, I've also conversed with someone from fi personally to attain the correct dimensions and specifications for this sub. i don't feel I'm going blindly as i have so much in the past. pmuerika, I'm not doing a 4th order anymore. i stated that in my second post. m5, i don't feel I'm defending illogical thinking as I've been happy with the outcome of everything I've built. illogical thinking would be if i did ignore everything that everyone was saying and plead that i am right and you are wrong. I've never said that any of you where wrong, i stated that I've been happy with what I've done, so that's not wrong to me. of course there's always more to learn, and i am taking everything into consideration but that's not gonna stop me from experimenting. i have the correct port length built into this box @ 32hz, I'm adding another section to it to see how it sounds. so if it's not what i want or like, then I'll remove it and have a box that is exact to specs. the sub is located at the opposite side of the port, firing at a 45° angle. should sound good, i would think as like I've said i seen boxes like this that people where asking about and other more knowledgeable people have replied positively that it was good. and they deaigned theirs with software, and i have correct air space and everything. so i have learned from this. and again i appreciate everyone's help. especially you aston, you are a very intelligent person, thank you.
