Triticum Agricolam Posted January 7, 2016 Report Share Posted January 7, 2016 I think a lot of the confusion in this thread is coming from the use of the word "tuning". "Tuning" is not the appropriate word when referring to sealed boxes (IMHO), the correct term is "sealed resonance". Part of the confusion comes from the fact that both a ported box's tuning and a sealed box's sealed resonance both use the same abbreviation "Fb". "Sealed resonance" and "tuning" are similar concepts but they not exactly the same thing. Other than the wording issue, I think ShadeTreeMechanic is spot on with the info it is posting.

ShadeTreeMechanic Posted January 7, 2016 Author Report Share Posted January 7, 2016 Well basically Fb is the frequency of the enclosure with a given driver X. No matter sealed, ported, band pass, 4th order, anything because it is the resonant frequency of the total system being designed. You can call it sealed resonance if you want if it makes it easer to understand. But if we start giving our own names to things, then it gets confusing to other people when they have to know that what we called it was called Fb everywhere else even if they are synonyms.

Lol, by calling it the "tuning" you are doing the exact thing you are accusing me of. If you don't like the term "sealed resonance", use "box resonant frequency" then or just "Fb", just not "tuning".

The box is tuned by changing the resonant frequency which was stated as Fb. It is tuned just like the strings on a gutiar? I guess thats where i was coming from. I think we are splitting hairs here. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...

ShadeTreeMechanic Posted January 7, 2016 Author Report Share Posted January 7, 2016 Yes tuned as in you can change the tuning of it.

MADVIBES Posted January 7, 2016 Report Share Posted January 7, 2016 I like the part where it's says professional peak limiter circuitry which guarantees distortion free music at all levels. They Could not possibly make up a bigger lie than that. No worse than the lie some companies tell about their Korean boards being more exspensive because they pay extra to have higher tolerance parts installed.
