Change the way you think about speakers with unreal accuracy

I'm telling you tuning is not something to base a design off of. It should be based on impedance matching and coupling. Tuning has a minor connection to this as well does Fs(which is what some people believe they have to make the cutoff for tuning at). And as far as a drastic difference, it really depends on the design goal. If the design goal is for SPL only, and the design is a standard ported design idea(constant port area with standard compression chamber, and most band-pass ideas), then this will have a reasonable affect. But, this is the exact reason why I came here....to help people like you understand that the design is much more complex than tuning, if you want to do it right. As a matter of fact, Transmission line enclosures are not even "tuned" if done the right way (and not the quarter-wave length path alone). So, tuning has minimal effects, like I mentioned before, in the larger spectrum of enclosure design.

Help people Like me?

Thanks..

You assume..

Then you post comments like tuning does affect FR or output..

I've been building boxes since I was 12 if I have a question I don't mind asking..

No offense but you take what I say and reinforce it..

Yes, help people like you. Ones who believe they know acoustics in and out because you have been building boxes since you were 12. That has nothing to do with proper acoustics, and I can guarantee that even then you were using basic math. I don't doubt you have knowledge, but I also believe its more related to building drivers than building enclosures. And that is obvious because you still argue the tuning effects.

Everything affects FR. That's common sense. I'm saying tuning compared to more important variables, is minor. You fail to see beyond a basic port and into more advanced acoustics, such as transfer function, which is highly likely you had no clue about when you were 12. The loudspeakers back in the day, in the 40s and 70s were the real deal, but even they did not fully understand proper acoustics. Its not just a physical means of output. There are binaural acoustical effects as well, that involves more than just angling the drivers at the common 30 degrees for staging. Things like that, like proper placement are still even being analyzed, so do not throw this age thing in there like it has evolved much over the years. It has some, but you still seem to be stuck in the older more basic forms of it. You have no idea what real acoustics are capable of yet...and that's not an assumption. You, once again, only see the negative of what I have said to you, so from now on I'm not going to be nice. I get it, you do not feel you need to learn more, trust me I have been there, but you have a lot to learn, as we all do. Even the best of us. Stop being so threatened, I'm not here to question your abilities, I'm here to correct and expand what you don't understand, but its obvious you do not want to believe what I am saying, so for that, though I do not give up on anyone, its clear you do not want to understand more and better yourself. But if you do have questions and I have some answers, if I do, expect me to chime in. I do not want anymore assumptions of audio on here. This is getting old and everybody else seems to be learning more but you.

Thanks cheif I won alot of shows based on ur advice..

I don't get into detail because alot of people don't understand alit of the yech talk..

Your going to sit here and tell me you build a system off of coupling and impedance matching?

It's more than that but you don't see me ragging you lack of complexity in explanation..

I built transmission lines and horns and wave guide 4th order 6 th order and that was before I was 15..

I didn't have a lisenced yet I was doing 150+ for burps with 1 dd 9515d dual 2..

I never said I knew it all but I've proven I know enough to design great systems..

Thanks for the advice, but you simply failed to realize that audio is my life and passion..

I can't tell you the countless systems I've designed that won at shows..

I've prototyped several woofers and Ive just some excellent woofers..

You babble about impedance matching and acoustic coupling yet you act like compliance bout enclosure and cabin as well as port amount other things like losses and dampening don't apply..

Well I hate to tell you but your simply wrong..

Are you serious? You take what I say and manipulate it very well I might say. You are actually taking that what I am saying means nothing else applies? m not sure how you got that out of what I have told you so far. You take the word "minor" and turn it into "doesn't affect", and take "major" as in "the only thing that does affect".

I think you are arguing with the wrong person about enclosure design, and I'm sure those on here will agree to that.

As far as what you have accomplish with your shows and such, ummm ok. I guess....congrats? I'm proud of you? Im not sure what that is supposed to prove to me.....

many people design great systems. Its common in audio for people to do great things. You are no different or better. You do not have to prove anything to me, I have faith in everyone on here to accomplish a lot.

Im sure you understood fully the concept of coupling and diffraction, and rarefaction, and reflections, and absorption, etc....on and on......when you were 15. SO, irrelevant as age might be in the world of knowledge (which somehow you compare the two like they go hand in hand), I'm sure you might have been in audio for a long time. A lot of us have...again not sure what you mean by stating that...is it an argument winner? "oh, he designed horns when he was 15...**** I'm done i guess" lol. I can guarantee you they were basic if that. Even the most knowledgeable designers of the most complex enclosures today still test uncertainties...I highly doubt you have a grasp of it all or even so more than I.

Anyhow, it is very clear that you are not here to help people, that you are out for your own self. So, I am going to call it quits on this thread, and whatever you have to say after, well, I guess you will get the last words. Again, congrats......i guess, lol. This is not worth my time anymore because you do not care about anyone else. It is clear it is all about you here. SO, with that, good luck on what you do, and well, God bless. I have others to help...I tried here, but obviously you do not want it, so I guess Im out. For others who read this, I'm sure you will catch the grasp of it soon enough. OP, get your head out of your arse and realize we are all here to learn and you do not know it all. None of us do. I am sure you have a lot to learn about design, but I'm not sure I want you taking that as a serious thing.

This thread should end very soon.

I need to add that you are completely incorrect about this assumption. I consider everything a variable that has an affect on the response, YOU just fail to realize the importance of each factor. Of course these things matter, why would they not and where did you get that they are not considered? I believe I have mentioned in plenty of posts of these variables and some of their importance. This statement really cannot be further from the truth. It is pure assumption and manipulation on your part. I think you fail to realize ANYTHING about me.

Anybody who designs enlcosures should be well versed in these terms and variables and consider every one of them in the design. This is something that should always be done.

Anyhow, good luck to you!

My typing is bad sorry..

You do the same thing..

I did it you u get a taste of your own medicine.

Frankly I'm done here I wish you well

Stick to building drivers my friend. Leave the enclosure work to me and the others.

 

[Papermaker85 5,000+ posts]

Btw I've designed and even built enclosures for free..

I'd do it for anyone who is a good person and enjoyed this as much as I do

Yea, right? Is he serious? LOL. This guy doesn't shut up.

 

[wenn_du_weinst 10+ year member]

I have been known to design an enclosure or 2 when I get bored

 

[Kangaroux 5,000+ posts]

What kind of enclosure is that last one? Looks like some kind of horn variant.

abc box good for sq and sounding loud. not so good for putting up numbers
