[QUOTE="geolemon, post: 361761, member: 547749"] There was no dictionary involved.. in fact no big words really involved at all. There was no need for reference, this is all common knowledge that as Josh said, hasn't changed since the advent of vented enclosures themselves. There's no mystery as to how they operate... and my points were addressed to [I]you[/I], with my points regarding how a vent is not a "hole in the box". If you read the post, I assure you, you will understand the post. [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] First off, my point was that neither sealed nor vented are superior."superiority" of enclosure type is primarily determined with respect to a particular subwoofer driver... And your subwoofer driver is primarily chosen based on your listening goals (one of the factors being whether it is ideal in the type of enclosure that best suits your goals). [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] You apparently are also fundamentally misunderstanding what "Cabin gain" is. In a small enclosed space, you get a natural rise in bass response - to the order of about 12dB/octave, beginning at some frequency roughly coincidental to whatever frequency's wavelength corresponds to your interior's longest dimension. So, in a small enclosed space like a car, where you have a "cabin gain" phenomenon causing your bass response to naturally rise by 12dB/octave, you [I]want[/I] a sealed box, with it's early-beginning, and slow-falling roll off... Because when combined with your "cabin gain", you actually end up with an "in car response" that's nice and smooth, [I]just like the sound engineers intended.[/I]. In a studio, or any large space, you don't have this phenomenon. Likewise, in a large space, your actual response tends to be closer to that "anechoic response" (the response plot you see when you model subs up in software). So in [I]that[/I] application, you often [I]wouldn't[/I] want a sealed subwoofer's response, with it's low-end roll off. It's all in matching the subwoofer, and enclosure type, [I]to your particular application[/I]. Something that you are not only demonstrating an inability to perform, but even comprehend, by nature of this very example you gave. Read up on "Cabin gain" and "transfer function" (as I mentioned before [IMG]//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif[/IMG] ). It's honestly quite amusing to hear you talk "snake oil". Again, as far as "vented doing more justice for low-end", that depends on your application. If you mean in a large open space - then yes. However in a car (this is a [I]car audio[/I] forum), cabin gain conspires against you. [I]In car[/I], your extension of the response will create a 12dB/octave rise, due to cabin gain, that will simply boost your low end disproportionally. That, by nature, is why "boom cars" exist. Because of that natural, acoustical phenomenon, known as 'cabin gain'. An acoustical bass boost. Some guys [I]want[/I] this unnatural, exaggerated, disproportional bass. But that's not a sign of superiority, in terms of [/i]sound quality[/i], which is what you are touting. And my statements aren't meant to indicate that you can't get good sound quality out of vented enclosures either - I run vented enclosures in my personal car. But I'd never make a generic claim that ported has better sound quality properties - it simply doesn't, it can't. [/QUOTE]
