this would make perfect sence if not for the fact that different speakers produce different frequencies of sound louder... IE; a middrange can barely even hit 50 hz.
Okay, you misunderstood my point. Let me re-ezplain it. When I said in an 'ideal world' I was referring to a world where we had the technology to build a speaker that could play flat, and with authority at audible listening levels, from 20hz to 20khz. We do not, so we split up the freqs. But, if we did have that technology, 1 speaker per side would be ideal (one sound point source, less anomolies in the signal from filters, etc etc). The more speakers you add, the more problems you also add. Therefore, the fewer used to acomplish the same goal, the better off you are. Period.
likewise a sub can scaresley go above 200 the frequency range of a speaker looks like a curve in contrast with volume... with most speakers x-overs are required to make these responces flater so yes a single sub would be able to play a range, say 20hz to 120 fairly flat.... even so this is still implying the use of x-overs to get the desired effect and it has to because every speaker has resonance.... a frequency that it produces more efficiently than all others... so basically this is not the ideal world, or your consept would work.
Uhm, no. First of all a 'sub' is only defined as a 'sub' based upon the frequency range it is playing. There are plenty of 'subs' that can also work effectively as a midbass driver, extending above your arbitrary 200hz region you pulled from the air. Granted, most true dedicated subwoofer wont play above 200hz effectively (or even to it), but this shows you are basing specifics theories on generalities.
Secondly, a sub does not require a highpass filter to play the subbass region 'flat'. I really have no idea where you got that, but Id love to see you prove it via testing.
A speaker's resonant frequency is not its sweet spot that it plays best, that is a function of the subwoofer in combination with the enclosure size/type/design. The Fs of the speaker affects the design of the enclosure, but ultimately you can tailor the system tuning via enclosure perameters. Yet another generalization.
The word is concept. And what I stated isn't merely a personal theory, its a basic acoustical fact. Most in-depth books, like speaker design cookbook, say the exact same thing.
maybe, i believe it can when applied right.
It can what? Perform better? Lets put it this way, if you cannot build a single-sized sub system to play 'flat' from, say 30hz to 100hz, well that's your problem, not a design flaw in today's speakers, systems or designer's heads. Again, this is an age-old arguement, you aren't the first relative noob (no offense) to think of it, argue its possible blah blah blah, but in the end, never proves it. Go ahead, go build some insane multiple sized sub system to play your 2 or 3 octaves, all blended perfectly, all level matched perfectly, and performing in ANY noticeably better wy than a well built single sub system. Go ahead and try. Then, when you are done, do it for the same money as that single sub system, or hell, even close to the same money, then come back here and tell us we are all wrong. If you do, I'll be the first one to congratulate you. But until then, you are simply a pipe dreamer with an attitude.
notice that the lower the frequency goes the greater the change... 20-21hz is alot bigger change then 20,000hz to 20,001hz in fact the ladder might even seem unnoticeable, this is where your idea makes sence...at the range that a tweeter covers it isn't that difficult to produce all of its frequencies relatively flat... a sub however is much more difficult... they can do it but it is more difficult... the reason for the obsession with bass is because thanks to companies like bose, focal, many other top companies known for their highs and mids, we have come to close to as good of midrange and highs as we can get... the major differences in some of the better sets can scarcely be told apart by the ear.. if not for analyisers and computers. no one has yet to create a sub with this level of accuracy and if they have they are dramaticly over-priced and often installed wrong... the bass is a very hard frequency range to get just right
So, its your opinion its easy to build a tweeter that'll play 4khz to 20khz flat? Do yours? I bet you'd be surprised.
There are plenty of single sized sub systems out there that play flat as a ruler from 20hz up well into their midbass range, and do it at volume levels you would find painful, so why your big need to break through some technological ceiling that does not even exist?
You do realize these companies you cite as making the perfect mids and tweeters, also make subwoofers right? Any theory as to why they make such near perfect mids and tweets, and yet their subs cannot play 20hz to 100hz flat? Subs are just that much more tricky to design? lol You are seriously talking way over your head dude, give it up.
My favorite part was when you said nobody has created such a perfect sub yet, but when they do they are too expensive and often installed wrong. Which is it, they do not exist yet, or they are over priced and installed wrong? lmao Can't have it both ways. Care to pull any more facts from your posterior to back up your claims?
the bass is a very hard frequency range to get just right.
Maybe for you. Care to explain exactly why you think its such a difficult task for everyone else?
i just hope the song you are listening to doesn't incorporate the "missing frequency" as a major part of its composistion...
See, this is the attitude Im talking about. Clearly I was talking over your head, but instead of simply asking me to elaborate, you jump to a conclusion, assume you are right, and talk trash as if you know what the hell you are talking about. You don't.
There wont be any 'missing frequency' if done correctly. Aprently you think a crossover is a brickwall, its not. Ever wonder why there are different slopes in xovers? Gee, maybe its to play with overlap/underlap...? Ever consider that your environemnt may be giving you an artificial boost at a freq very near your xover point, and how to fix such a problem? Hmm, maybe if I 'underlap' that freq so both the mid and tweet are trailing off at that freq, coupled with the artificial boost equals *gasp* a flat frequency response. Chew on that situation a little bit before you contemplate coming back with yet another smart-*** comment that shows you dont even fully grasp the topic, mmmkay? //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
