  • damn! adire audio's brahma sub! that was the shit back in the day!!

  • so tuning..meaning turning your gain down on the amp and such..the bass down on the amp..right..just tweak till ya dont get this distortion right?..

  • my z5500 clips at like half volume...

  • Lol @QUIX4U, the most annoying asshole I've ever seen on the interwebz. -.-

    The bastard comes back to the video just to complain also, ROFLMAO at his post dates - "1 year ago, 10 months ago, 3 months ago". Life well wasted Mr. CAPS.

  • @MBP6705 Also, don't use bass boost. It's pointless and will only cause you to damage you subs quicker.

  • @MBP6705 it's when the audio wave clips off the top of the signal causing the subwoofer to be momentarily stationary. It is not always this noticeable. If listening to your sub and whil turning up the volume it does not get louder, you are clipping it. The sub should sound clear, not muddy. If you've never tuned an amp before it is best to let a professional or someone who knows what they're doing tune it for you. Go to a local shop, they'll most likely do it for free

  • What exactly causes clipping?  And is it always this obvious? I'm a car audio noob and I'd rather not damage my system.

  • @QUIX4U just because u are using a bunch of big terms doesn't mean you are correct, "clipping" means your amp or your HU is sending signals out that are too strong and the ends of the frequency waves are being "clipped" off, you cant hear clipping u have to use an o scope or DD-1 to tune that out... And u saying distortion doesn't hurt the driver is COMPLETELY false, distortion means that the subwoofer is not moving in a perfect linear motion, it may not be instant but in time will hurt the sub

  • What's with all the "know all" people in the comments? Your hearing must be fucked up for judging a video and not understanding a single thing about speakers. GET YOUR FACTS STRAIGHT!

  • Ok peoples.. NOW that you think you know what to "look" for.. take another LOOK here.

    At the 04 sec mark .. the VERY OUTER BASKET EDGE is seen to vibrate (indicating that the basket is vibrating against the surface the speaker is sitting upon) BUT -- almost the entire rest of the time.. the uploader has DELIBERATELY HIDDEN .. any vision of the basket's outer edge.. (so that you cannot see.. whet they see.. "just" a bouncing speaker -- on the table)

  • @destruction12100 Plus: most people do NOTrealise that when they run ONLY two speakers on a "+(o)-" common ground Upper/ Lower "three rail" 2 circuit DC amplifier- THERE WILL ALWAYS APPEAR across both speakers a DOUBLE VALUE DC RAIL VOLTAGE (irrespective of WHAT the actual power output of the amplifier is doing with the AC component). Most of the time- the amplifier USES DC values as a compensator to the AC output. BUT- if one output should "short_out"- DOUBLE DC "will" appear across ONE speaker

  • @destruction12100 (p.s) Although distortion sounds really BAD & as I said- actually does NOT harm your speaker- it can BLOW your speaker coil clear OUT of the magnet- then if the coil then doesn't CLEANLY "go back into" that tiny wee slit "properly" then that sadly WILL actually physically destroy your speaker's COIL"structure" but it WILL not "burn it out" like a DC rail voltage will.

    AND a DC rail supply voltage can OFTEN appear across a speaker even when an amplifier is set BELOW 70% maximum

  • @destruction12100 Oh & distortion (as you said you get) is actually totally different to & a totally different cause from- anything ot do with clipping.

    Distortion comes from a 'distortion" of the sound signal- be that by way of an "missmatch" with your speaker's impedance (to that of the amplifier) or because your amplifier is providing TOO LOUD a signal (WITHOUT BEING CLIPPED) for your low powered speaker to handle (p.s- distortion although it sounds BAD actually does NOT harm your speaker.

  • Which is.. the very exact reason .. WHY.! Why I always try to utilise small "resistive loaded" filament lamps .. that -- have a small delay effect .. before the maximum levels are approached.. but which "flare' wildly -- between almost & just above .. the maximum levels.. so that I CAN SEE -- long before i can hear .. exactly what my speaker coils are getting.. between AC (loudness) voice coil power & DC (Heating) loss

  • Thus: when I say -- clamp that sucker into the correct enclosure & PUMP IT HARD .. what I mean is to it's LOUDEST (within it's operating limits). which is a lot louder .. at lower "master" settings .. than most will ever admit too -- as the human ear.. doesn't spot the loss of loudness.. at high levels.. that occurs when an amp is "wound" too high (plus.. even IN certain music "tracks' the levels vary so vastly .. if U do not keep adjusting the levels - U WILL CLIP SOME & under power others

  • Therefore- when I "run" a NINE (9) CH DIRECT CONNECTED DEPLEXER DECODER to "power" a NINE (9) CH ultra_surround (ANALOGUE) system- I am "always" running that at the exact impedance match- across ALL frequencies that the amplifier "sees" as just a 2 ch "two_speaker_circuit" (it's NOT) as it's an "electrical" 3_phased multi_pole "type" of MOTOR CIRCUITRY of my OWN Industrial "design" (& is one that I have developed over the past 45yrs) AND- one that has been specifically designed to MATCH EXACTLY.

  • The reason that I CAN get MAXIMUM "volume" CONTENT 9most of the time .. for what would appear to be an extremely LO POWERED AMP- is not because I am cranking the master LOUDNESS controller well above it's safe operating level- but that I am "running" a fully balaced (totally calculated) EXACT impedance_match (final circuit).. exactly matched to the amplifiers actual ELECTRICAL CIRCUITRY (which incidentally- is "not" limited to the "actual" 2ch UNBALANCED "vague" output referencing- that U use)

  • If you want to avoid any form of "clipping" (and it's fatale effect on speaker coils..

    NEVER EVER RUN AN AMPLIFIER .. anywhere above 70% of it's CONTROL LOUDNESS.. on LOUD INPUTTED MUSIC.

    The "only" reason that an amplifier's manufacturer.. will "provide" an amplifier .. with a master controller .. that ALLOWS an amplifier to go well above it's AVERAGE OUTPUT .. is because a "lot" of sources have minimal p2p voltage outputs- such as a wee crystal radio set OR a phonogram's LP player- RCA out's

  • "PURE DC" will NOT create an in & out (push/pull) effect from a speaker coil & thus a SPEAKER will actually be very very silent just before it's coils COOK (on PURE DC). What most 'think" is the sound of clipping is in fact- the already destroyed coil's FORM & INSULATION VARNISH (of it's coil wires) as the "bulbous" deformed coil starts to "rub" on the magnets sides (as the coil TRIES to move within).

    BUT- long before this happens there WILL be a faint smell of cooked speaker insulation varnish

  • "PURE DC" is what the amplifier WILL DELIVER- when the outputted signal- goes ABOVE & beyond the "level" of the voltage supply rails AND as speaker coils are only self cooling when ONLY running on AC (They will heat rapidly- if any DC is present- AND DISTORT- not just clip- on DC "Heater_element" wattages). Mostly- speakers are fairly robust and "will" allow U maybe 1 or 2 of these- an hour.! BUT NOT ALL THE TIME ! Clipping doesn't sound 'like" anything. (OTHERWISE HEATERS WOULD SCREAM WHEN ON).

  • The problem is simple.

    WHEN someone uses an amplifier with a "rating" lower than the speakers; THEY "often" INCREASE the input signal strength (without considering the function of "amplifying") such that- when an amplifier is RUNNING near to- or AT- it's maximum rated output (under normal conditions) it is also running very near (but not at) it's MAXIMUM DC RAIL VOLTAGE. Go above that level & you "loose" loudness & thus tend to "crank" it more. That's a fatal mistake- as U are running "PURE DC"

  • nice subwoofer

  • orite i need some help . my spekers either distort or clip when volume is turned up . i always put bass boost all the way up . but also i dont get the distortion or cliping with songs that arent bass boosted . can anyone help me figure out whats cliping and distortion . i have a qx2-1440 kole audio amp .

  • What clipping lol. Hardly any. Clipping is when the coil is over powered and bottoms out on the magnet

  • @juniortore1 your fucking stupid and very very wrong.

  • @18abVFL no, that is a true example of clipping. Now, as in this video, there are minor versions of it where some frequencies are simply lost through distortion.

  • @juniortore1 You are fucking stupid, that's called bottoming out. Clipping is when your amp is trying too hard and accidentally sends your coil a DC signal instead of an AC signal.

  • @kintarben Well, in that case, I do not see why you had to be so rude about all of this shit. I wasnt rude about my original comment and here you are FUCK YOU FUCK YOU FUCK YOU... Anyway, thanks for correcting me, now we can go about our business

  • @juniortore1 You're the one running around YouTube spreading WRONG information when people are watching this video to be informed.

  • so when it's clipping it means that my amplifier is working beyond its capability ?? i have a cheap amplifier and i want to test if it will do the same thing but at the same time i don't wanna fuck it up by clipping or whatever.

  • @ExtraTerrestrials

    ya, clipping = amp is putting out more than it can process so it just sends out peaked signals... you gotta turn ur gain down or turn off any bass boost, or turn head unit volume down lol!

    umad

    

  • @ChromiteIsBestRogue got alot better amplifier now.... rockford fosgate

  • so how do you get rid of a clip? turn down gain? my subs do this when i turn them up, but i dont think i'm bottoming them out.

  • Clipping means making a sinuswave into a square wave.(simple as that)

    This vid shows how clipping sounds.(but clipping is started before it is heared.)

    Conseqeunces of clipping are:

    -Heating up subwoofer coils faster then non-clipped.

    -Heating up the amp

    -sounds like shit

    -Lowering the maximum SPL(if u are clipping badly. )

    - and a few more but i can't think of them at the moment.

  • @epiphonesg007 exactly. Thats what I've been trying to say just in a different way with a few different details.

  • SEEN AND HEARD- was NOT (unfortunately for you) described as "clipping"- but is an inherant "mount" vibration- as your speaker actually "bottoms" out as the coil actually physically "hits" the bottom of the magnet's receptical (whereas amplifier CLIPPING is the electrical "result"- reached_by (& STAYING AT) the supply rail's DC voltage which CLIPS the amplifier output- rendering it unable to SEND a higher voltage & thus "clips" each peak off frequency signal paths (& an entirely DIFFERENT SOUND)

  • It sounds like the subwoofer is bottoming out but it actually isn't :)

  • for everyone that wants to know more about clipping. google "amplifier clipping PDF" and open the first one you see.

  • ok, 2nd time lucky lol the amplifier cannot supply the power that is needed, giving clipping. Forgive me if its wrong again but im in my first year of A level electronics

  • @turtlelips76 Ur forgiven .. actually "amp clipping... usually occurs LONG before any "sound" is heard .. and it is NOT a rattle rattle as heard here .. but rather a "flattened" DEAD sound .. as when a DC signal is"firing" through the coil (IN IT"S CLIPPED FORM) a DC signal - actually DOES NOT VIBRATE a "speaker" .. but rather allows the speaker to "stagnate" at a certain point .. USUALLY "just" as a faint "bzzzzzzz" sound .. BUT that is when PURE DC "current" is at it's highest AVERAGE VALUE

  • basically you loose some of the frequencies therefore loosing sound

  • ummmm.....no, try again

  • @IceburgSlim8788 Ummm yes ? U try again- CLAMP that speaker- into a properly SIZED speaker Enclosure (manufacturers specify vented or otherwise) AND again do your test WITH the proper enclosure STURDILY screwed, bolted or CLAMPED onto a non_reasonating bench top (OK) AND THEN - you will truely be able to DRIVE THAT SUCKER .. well beyond the useless - FREE TO OPEN AIR ... bottoming-out flap_flap sound (you got) when abusing the speaker - OUTSIDE of an enclosure - without BACK PRESSURE on the cone

  • @QUIX4U Dude WTF are you talking about. This is an example of what amplifier clipping sounds like. No it is not the magnet vibrating nor is it bottoming out.

  • @IceburgSlim8788 Sounds like the coil. What amp were you using, Because if your clipping at such a low volume then that amp sucks, that is why alot people are giving you shit because amp dont really clip at low volumes.

  • @IceburgSlim8788 That's what I don't get, people actually think this rattle is cool, while killing their systems, amps, & speakers. It's so easy to hear the distortion, that it drives me nuts when people think that's how it's supposed to sound! I love deep low bass the glitchier & grimier dubstep the better, but CLEAR sound without rattle is how it should be. You are RIGHT on, your example is perfect--the people who aren't getting it are those who need an excuse for listening this way.

  • @IceburgSlim8788 Re Ur: [quote] @QUIX4U Dude WTF are you talking about. This is an example of what amplifier clipping sounds like. No it is not the magnet vibrating nor is it bottoming out. [unquote]

    It is NOT the sound of 'clipping". A clipped signal has a DC value (at rail supply voltage) DC= direct current & does NOT produce ANY sound in a speaker- as the COIL IS STATIONARY (whilst DC "runs" at ONE LEVEL). Speakers ONLY make a sound when there is a varying AC voltage. That speaker bounced.

  • @IceburgSlim8788 And the reason I "know" it is BOUNCING .. is the exact same reason .. ANY VIBRATOR WILL BUZZ.. when it is LOOSELY 'sitting" on a solid surface..

    THE SPEAKER SEEN IS JUST "sitting" ON TOP of a solid bench & WILL act- just like Ur iPhone does- (when ringing on Vib Alert). That speaker is simply "being" hard driven- such that as the INERTIA of the coil diaphram rises UP- it WILL pull the entire speaker UP "micromillimetres" OFF the surface & it WILL impact down again and THUS BUZZ

  • @QUIX4U why do people like you always try and use your knowledge without looking at the actual vid and using common sense first? your comment is a waste of space because u overlooked something to the max when it is nothing like that. maybe if you open your eyes you will see better. you must be a moron if you think its bottoming out. smart ass..

  • @QUIX4U mine is in a properly sized box but it still distorts when i turn it up

  • @destruction12100 Aye & it always will. Why?

    Because almost everyone (either accidentally or deliberately) FORGETS a major rule of amplifier manufacturers.

    ALL AMPLIFIERS are "rated" at a specific output (for a specific input). Such that at say 1v (peak to peak voltage input) the amplifier at it's LOUDEST (note: not volume content- but LOUDNESS level) will deliver it's MAXIMUM rated output. (for a 1v p2p "very specific frequency").

    However- MOST put far above 1v p2p "in" & wonder why it clips

  • Wrong

  • @turtlelips76 ? NO .. you LOSE - not one frequncy.. ALL you lose .. is "anything" of the UTMOST TOP .. of any applied signal .. across any frequncy that reaches the amplifiers "INTERNAL" DC supply rail's "maximum" voltage .. and whenever that 'maximum" is reached .. whatever frequency that "got there" stops AT THE DC max voltage .. instantly "reverting" to DC RAIL VOLTAGE .. from the AC speaker signal .. thus the speaker sees lowere than DC rail voltage as an AC signal PLUS a TOP MAX DC voltage

  • dumb ass

  • what is clipping?

  • when you push a signal (or have gain or bass boost) up on your amp which makes a wave that usually looks like rolling hills turn into a hill with a plateau on top thats what the clipping is cutting off the top of the wave

  • ooh so you need to give clean signals to the subwoofer...nice wavey signals rather then blocky :) am i right?

  • exactly

  • @IceburgSlim8788 Actually .. and yes .. YOU DID think you were "getting" clipping.. BUT .. all that you ca hear .. is a speaker .. designed for a "vented or non-vented .. FIXED "AIR" VOLUME "enclosure" ... which is simply "sat" magnet down .. on an UNMOUNTED "stand' .. and with ? OPEN AIR "fully" NON_ENCLOSED .. "space"' ... allowed to "JUMP up and down .. on it's magnet .. on that table or whereever YOU sat it upon ... whilst the CONE .. was allowed to FREELY BOTTOM OUT (extend & retract) !!!

  • atomdragon4 no this just and example of too much signal being sent to the Speaker or Amp or from the original recording itself.

  • So clipping is a problem that comes from the receiver?

  • i hate clipping man. ruins the bass quality

  • Ruins the voice coil...

  • @masterwolf1212 and the amp !!!! lol

  • @masterwolf1212 Actuually ..NO- "clipping" in itself.. does NOT ruin a voice coil per se`.. IT .. simply allows a DC ... pure HEATING current to "flow" in a very fine wire .. (which is coiled tightly) ... and as such - allows said coil .. to become a very GOOD heating element.. which almost instantly .. BURNS all the electrical insulation .. OFF those hair thin wires .. creating an almost DEAD SHORT across the amplifier at the HIGHEST DC VOLTAGE ... that the amp can deliver (KILLING THE AMP)

  • @QUIX4U Clipping is bad for the sub. Basically when the subwoofer moves, the thermal energy from electricity becomes kinetic energy, meaning the movement of the coil cools it. Now when a dc signal from the amp is delivered to the subwoofer, it creates a square wave, seizing the subwoofer out, and inwards, so there is electicity flowing to the coil without the transformation happening, heating the coil.... I've been in the hobby of audio for a while now. I know this stuff, I don't need CAPS ether

  • @masterwolf1212

    a while in the hobby of audio? XD

    Best joke ever, you're a 14 year old so don't talk like you 'have been in the game forever". I haven't flamed u. ;)

    I just pointed out you don't need to act like a 'know-it-all"

  • @epiphonesg007 Ohm my gosh. Your just going to keep finding videos I commented on and posting shit arent you. I know what clipping is, so thats why I commented. Look, you don't like me, I don't like you. I'm 14 and all your doing is saying "your 14 blah blah" I probably know much more than you did at the age BUT I DONT KNOW. You were 14 too at once, you may be now IDK! So nomatter what I say your going to counter it. We are never going to agree. Its pointless. Were just trying to hurt feelings.

  • @epiphonesg007 As a bonus that guy was wrong. He was saying that melting the thermal wrap around the coil is good, in some cases yes, but doing so too much will fry the woofer. But like I said, this is pointless. You commenting to me has NO PURPOSE as me commenting to you. All were doing is getting nowhere. We were BOTH wrong and are BOTH being assholes, and I apologize, not saying I was 100% wrong. We are BOTH wrong, so if we can just come to a conclusion, maybe we can be freinds. Im a nice guy

  • @masterwolf1212

    Thermal wrap around the coil?

    You mean the glue that holds it together...?

    And yes i'll comment on it if u type comments like : 'i'm into car audio for a long time."

    Or : I've been in the hobby for a while now." that's what bothers me 14 year olds talking like their big and spreading false info.(not saying everything you say is wrong ;) )

    And i'll make another comment to explain clipping.(and by the way i'm not 14. :) i'm 22 like u can see, i've started car audio when i was 13;)

  • @epiphonesg007 Okay. But on the other hand you shouldn't be "bothered" by a youtube comment. Its just youtube, a site where people comment that you don't know. So you shouldn't take it so seriously that a comment bothers you. But I just mean I've been reading up about it for a few years, and talking to a few very eductated OLDER freinds of mine. But I'm sorry I bothered you, but either way I was right about clipping. Square waves make the coil go up, freeze, then down, freeze heating kinet-therm
