AV12 excursion

[d3dreaper]

@critcal then please explain why my 50 watt amp is producing louder and cleaner sound than the any other amp ive wired/played/heard that is pushing 1500watts or less...

[d3dreaper]

Lmao i know what everyone is saying here... Maybe its the way im explainin thats all fucked up

[sharig11489]

how many watt's? ae makes some amazing speakers, i plan in using 2 new av 12's on 2 cadence ia7's should get around 2200wrms, gana use a 6th order bandpass that john is going to help me with

[JamieLovesLemons]

It should be noted these are *not* 'car audio quality'.. If you want crap go buy some Fusion's.

These are hand built Acoustic Elegance AV12's and will *not* shake themselves apart. (in response to the guy a few comments down)

[brett248vista]

The AV12 was spec'd out to be used free air or sealed it can be utilized either way, I know as I know the owner/creator John of Stryke Audio.

It's nice to see another AV12 out there. I run an AV12 (was probably one of the first guys to pre order one) I run it in an overdampened sealed enclosure driven by a 500 watt RMS Bob Carver Tracking Down Converter. It's in my home theater.

fukin awsum ******

beats my 4 sony xplod

[QTip05]

zplod sucks my nutz kuz

[veinsblack]

watz that song called

[immacomputer]

Click the "more" button for the description and it lists all the songs in the order that they are played. There are six songs played so there is no way I could ever guess what song you're asking about.

[Malmenswe]

DUDE , thats some serious shit u got there

[jules122006]

Guys chill lol u argu 2 much lol foam suround is delicit for sure

[rlcowboy]

well another way to damage that driver is to keep playing with your hatch up out into the open air. It will put a strain on your driver's suspension causing suspension fatigue. Thats not an opinion, it's a fact! Some drivers will take longer than others to be damaged depending on that driver's suspension. But don't take my word, do a little research.Also 3/4 BC plywood is NOT as accousticly sound dead like Medium Density Fiber board is, thats why it's the prefered material to use.

[immacomputer]

No, sorry, that is just not true. While loading the sub will help in cone control, playing it not loaded will NOT damage it unless it is driven pass its mechanical limits. The sub is NOT playing free-air just because the hatch is open. How many rock concerts have you seen that have the subs constantly being loaded towards the wall? I'm sure they blow drivers every show don't they?

[rlcowboy]

Hey man, I aint trying to be a D***k about anything, it's just I've been installing car audio for many yrs now & have seen it all, including damaged drivers because of suspension fatigue. The drivers EVENTUALLY wiil fail due to the suspension being damaged if u keep playing it without anything to load off of. The speakers at a rock concert are set diferent & with alot stronder suspensions than car audio drivers. I've seen it happen twice in the last 15 yrs.

[immacomputer]

No, sorry, you are just an idiot. You have also proven that you have no clue what you're talking about all over the place. You might as well just give up.

[audioamateur]

rlcowboy playing with the hatch open will not do anything. It's like saying.. i don't know something stupid, like 'it's a fact'. Explain why, give me the physics about it. If this is the case why aren't home subs damaged? the actuall sub 'loading' will have an effect on its excursion, i.e sealed boxes, ported boxes and the tuning frequency, but have the car open doesn't do a thing to it.

running four hi-vi sp10s in custom vented enclosures at around 2000W rms from some bash amps. i run a sub in each corner of my 12' x 15' bedroom. i've never turned them up above 1/4 because my parents are always home, but i would bet money that if i turned them up to 3/4 my entire room would collapse.

ps : each subwoofer weight 167 pounds and is made from triple laminated 3/4" good one side plywood. i used four pe500W bash amps.

[pimpdogg1993]

Youre not supposed to use plywood for sub boxes... And Ive never heard of a subwoofer weighing 167 pounds. The Kicker Solo-X 18 weighs nearly 100 pounds, and the MTX Jakchammer weighs some 350 or so.

[bradenn]

the entire unit, including enclosure, driver, passive radiator, amplifier (which is built in). and who said i can't use plywood?

i can use whatever the fuck i want.

[pimpdogg1993]

Plywood doesnt have the greatest damping factors, and the only wood you should use is 3/4 inch MDF, or birch or apple plywood.

bad sound

[Raverland]

Go on harder (=

Listen Music of thist DJ -> Yakooza <- He have a Song (STRONGER)! This song harms your Subwoofer.

[immacomputer]

Sorry, but music and frequencies will not harm a subwoofer unless it is played beyond it's mechanical or thermal limits.

The songs you mentioned were pretty interesing though. Thanks!

[Maxzoe20]

A square sign wave output at frequencies below 200 Hertz even at the supposive "rms" electrical rating can drive a voice coil to thermal overload, especially low compliance woofers.

[immacomputer]

You're close... the square wave introduces more heat due to more power. The wave will not damage the driver but too much heat caused by the extra power could damage the driver. A clipped signal from an extremely low power source (lets say 20wrms source) will not damge a high power driver (1000wrms and up).

[Maxzoe20]

Not to be objective, but I personally fried a 10" 600 watt woofer with 30 watts rms. A bad characteristic of transisitors is the tendency to "hang" once clipping begins,and so each sign wave, both +&- can last a duration (as I've seen)up to almost 8 times as long as the original signal( this is dependent on the driver's electrical parameters because a driver is a reative load, and amplifier damping factor).Using a signal generator I can manipulate the sign wave shape and there's a difference.

[d3dreaper]

well when u try to force a 600 watt sub on 30 watts it's like making a guy who can only lift 30 lbs pick up 600 lbs so you are goin to blow ur sub and possibly ur amp....

as for the square wave it's goin to act like a clipped signal because it basically is a clipped signal and it will damage ur amp and sub

[dnick454]

That is quite possibly the stupidest comment I've ever heard. You CANNOT BLOW A SUB BY FEEDING IT TOO LITTLE WATTAGE. Even by clipping the hell out of an amp, if the amp is way lower than the sub's capabilities, a clipped signal won't matter, it's just too little power to overwork the subwoofers thermal capabilites. Now, if you have an amp that is doing the same or more rated power than the sub, AND you clip it, then yes it will blow. You couldnt blow it on 30watts if you tried. Please dont post

[d3dreaper]

Apparently you haven't experimented on audio equipment as much as i have... I can tell you from experience of several different subs that i have blown them on less than 1/4 of their rating... So don't assume i'm just blowing smoke up your ass when i say that because i have experienced it more than once and it wasn't because of a wiring fault...

NOW if it was a tube amp you would be able to push 40 watts and make it sound like 500 just because of the characteristics of the tubes themselves

[immacomputer]

You are very wrong. If you hook up a 600 watt driver to a 600 watt amp, how much power do you think the driver sees when the volume is about 10% up? Do you think it sees 600 watts at 10% and 600 watts at 50% volume levels? If so, you need to back away from your keyboard.

Power is power and a 40 watt tube amp is going to have roughly the same output power as a 40 watt transistor amp. The difference is in the damping which will really only affect the driver around resonance.

[d3dreaper]

huh?? i never said that..... i do understand that power is power and i know how volume works.... but my point is ithat you can blow your amp by having a sub that requires more power than your amp is rated for and you also run the chance of blowing your subs on a clipped signal (depends also on the quality of the subs and how the voice coil is designed)

[immacomputer]

You can blow your amp based on user error, not the rated power handling of the driver.

A clipped signal is no more damaging than a sine wave with equivalent total power. Square waves carry more power due to added harmonics to the fundamental frequency. If the new power of the square wave is in the functional power handling of the driver, the driver will be fine. Period. The shape of the waveform has NOTHING to do with it.

[blazinloud]

@d3dreaper dude, you have no idea what your talking about....heat is usually the main killer, clipping=distortion=heat=fail

[criticallistenphile]

@d3dreaper Um, no: "if it was a tube amp you would be able to push 40 watts and make it sound like 500 just because of the characteristics of the tubes themselves" That statement is absolutely ridiculous. 1 watt is 1 watt, whether it is a tube or transistor supplied watt. refer to "Law of Conservation of Energy". A speaker powered by a 40 watt transistor amp will not be louder than the same speaker powered by a 40 watt tube amp. Volume is energy-sound energy it doesn't increase magically.

[Monkeypumper420]

WOW!!!! Someone who actually knows what they are talking about! IMPOSSIBLE! Hey man you don't belong here, this is the place for retarded, stubborn cry babies remember? Lol!!!!

I thought intellegence was impossible to find here. I guess you learn something new everyday... Thanks for actually having a brain, unlike 999.9% of the others here...

rocks

Not bad :P
