A loudspeaker system of rules can cost as little as $ 35 . Oras much as $ 350,000 . As a normal individual , you likely have just one question about speakers that cost as much a Ferrari : What . The . Hell .

How Speakers form
Especially when you consider just how simple the overall mechanism behind a stock speaker is : It impress air . Essentially , what happens in a speaker — loudspeaker system , to be technical — is that the alternating current from an amplifier runs to the speaker and through the voice coil ( which is just , look for it , a gyre of wire ) turning the coil into an electromagnet . That , in turns , creates a magnetic field between it and the lasting attraction in the driver . As the current replacement between positive and damaging , the magnets are draw in and push back , moving the strobilus back and forth . Voila , it emits the solace sound of Bach or Korn . ( Driver diagram from Wikipedia’sunusually particular loudspeaker clause . )
But that ’s probably not quite what you cogitate of when you get a line “ speaker . ” You ’re likely guess of a boxwood with a traffic circle thing and perchance a hole in it . That ’s actually a loudspeaker system , and it actually has more than one sort of speaker inside of it , phone drivers . That ’s because the driver tuned to deliver eminent frequency — a tweeter — ain’t so sound at delivering bass , which is why you ask a woofer or subwoofer ( miserable and miserable ) . And then you ’ve got mid - range speakers — for mid - range sounds — in higher - close systems . Your average GENERIC SPEAKER COMPANY set skips this middleman . So generally two or more driver are pig out in a box seat or console , call an inclosure .
Lovely , but that does n’t explain what distinguish these$107,000 YG Acoustics Anat Reference II speakersfrom the $ 50Logitech Z-2300son my desk — which are even THX certified . So , we enlisted some help : Cnet ’s Audiophiliac Steve Guttenberg , who live and breathe speaker rate from the sensible to the ludicrous , and Paul DiComo and Matt Lyons , speaker guy who amount from Polk and are now atDefinitive Technology .
If you read our visibility of Audiophile Maximo Michael Fremer “ Why We Need Audiophiles , ” it probably wo n’t storm that when ab initio asked simply , “ What the divergence between ten dollar loudspeaker and ten thousand dollar utterer ? ” the Definitive guys ’ initial answer was , “ Well , it ought to be that they sound better . ” Even Steve severalize us , “ You ca n’t apply a Consumer Reports form of index to something that ’s as subjective as audio quality . ”
No , but earnestly .
The Goal of a speaker system
A verbalizer ’s ultimate goal is “ to sound like reality”—the elusive dragon that every audiophile following — so on a broad , not - very - utilitarian level , how unaired it come to matching that realness is the difference of opinion between serious and defective , expensive and cheap loudspeaker system . To be slightly more proficient , the “ specification ” is clarity : The low the deformation of the original sound it renovate , the better the talker . In fact , basically every other spec , every confusing routine you record on the side of a box seat is actually altogether meaningless , according to both Steve and the Definitive guy . Steve singles out Watt as “ one of the more useless specifications ever create . ” If you have to look for a number when buying speakers , Steve said one that ’s “ kind of useful ” is sensitivity / efficiency , which would be something like 90dB @ 1 watt , which associate how garish a speaker will play at a give powerfulness level .
Three Characteristics
But when iron , there are a few qualities Paul and Matt from Definitive singled out in amazing speakers — what they call the big three :
• More active range , or simply the ability to wager louder without sounding like trash as you crank up the book . With good utterer , you want to keep crank up it up , like speed up a fast car .
• good bass . That does n’t mean louder , “ but better . ” It ’s more melodious , and not miry — you’re able to in reality hear individual notes , an erect acoustic bass being plucked .
• “ A very natural tone . ” Timbre is the “ flavor color ” or how lifelike the auditory sensation is — if you recreate the voice of someone you live on a speaker with excellent timbre , it would vocalize exactly like them . Or if two dissimilar instruments play the same note , you ’d be capable to assure them asunder very easy and cleanly .
Beyond that , what audiophiles are look for — which Mahoney advert to in the audiophile profile — is a verbalizer ’s ability to create an image , the photo . That is , its ability to create a sense of three - dimensional sound . The set trouble of designing talker , say the guy cable from Definitive , is that “ physical science is dogmatic . ” So every speaker is built around a set of compromises .
Size
To put that in some concrete — rather than seemingly religious — terms , you ca n’t have a little speaker that sound unspoiled . So one defining quality of six - figure loudspeaker is that they are tumid . They have big woofer and tweeters . More open area think of better phone . There are also simply more drivers — every driver you total is like when you supply another string to a guitar , to create a better - nuanced sound . So , for instance , a $ 300 speaker from a “ quality producer ” you ’ll get a 5 1/4 - column inch woofer and a 1 - inch tweeter . A $ 3000 duad of speakers might have two 5 1/4 mid - range drivers and then a 10 - column inch woofer .
Build Quality
Build quality is the other thing . A “ deadened box , ” or an inclosure that does n’t make any phone of its own — since that ’s aberration — is primal and something that be a lot of money . You just desire sound from the drivers themselves . The quality of the woofer and tweeter themselves , obviously , come into looseness — their ability to cover more power , since that ’s what translates into bulk .
At the uttermost end , Steve suppose , they can just handle more power without break off — as the copper conducting wire inwardly heats up , it can distort or melt , and the number one wood gets messed up . Pricey speakers do n’t do that . In price of exotic material or building , Steve mentioned medallion tweeters , which are only in the gamy - end utterer systems — they’re “ literally a piece of aluminum foil that ’s suspended between magnets that vibrates back and forth ” produce excellent pellucidity . Better speakers also have intricate dividing connection to verify the right signals go to the right-hand berth — they get more complicated as the price goes up .
Dollar Figures
So how much do you have to expend to get a skilful organization in the eyes ( ears ? ) of an audiophile ? Definitive recommend $ 1000 for a house - theater component setup . ( In other words , do n’t buy a home theater in a box . ) you could also get a pretty becoming pair of “ inert , rude sounding ” speakers for $ 300 — they “ wo n’t pink your ass ” and wo n’t be slap-up as some things , but they ’ll be alright . There ’s no sorcerous one - size - scene - all speaker system , however . It depend on the elbow room and the situation . ( If your lounge is against a wall , skip the 7.1 surround , says Steve . ) heavy speakers tend to sound good than light ones , though that ’s not an absolute .
But what ’s the upper limit ? Well , there is n’t any . Paul from Definitive read he heard these$65,000 Krell Modulari Duolast month and “ was mezmerized . ” It ’s like wine to enophile , Paul sound out . As Steve lay it most simply : “ To people who are into it , it ’s deserving it . ”
