I've got 2 Sony XSL-1265G 12" 400watts rms subs. How conservative is the wattage rating? Would they blow if they were fed 500watts rms each? If they would how long @ 500watts rms before they'd blow? Thanks.

 

i don't think they'll take 500 watts RMS that long. maybe 20 minutes? who knows.. its sony..unpredictable

do you know where they get their name?
editk, thought they were XPLODS LOL, they have a habit of blowin up, how do your sony subs sound anyway, sony...and....sub..just dont go together, sony...and....explode...yeah, thats a match!

 

If it's 500w from a Sony amp, then no prob. If it is a reputable amp, then be careful.

aka turning down the volume-&gt;aka lowering the preout voltage-&gt;aka lowering the votake the amp receives-&gt;aka less voltage=less output-&gt;less power amp makes-&gt;nto really putting out 500 watts RMS

Edit: an extra 100 watts is not much at all, I am fully confident that the subs can handle it, remember it is how clean the sound is not how many watts that plays a bigger role in the sub blowing.</TD></TR></TABLE> which way can i blow a sub faster? 1000 watts of clean music to a 300 watts RMS sub or 300 watts of distorted watts to a 1000 watts RMS sub? i'm just a newbie at this so if you can clear up a few things..that would be great

LOL, sad and true.

 

keep it below 400...500 might be pushing it...

 

I blew two Infinity Perfect 12's which are rated at 1,400 watts(max) with a Phoenix Gold M100. I also blew two MTX 12's with this amp, not just blew them like as in distorted sound, but I blew the voice coils right out of them, they made no sound at all when they went. The amp is supposedly rated at 100 watts rms, but it is known for having mad output power. I don't think that those Sonys would handle anywhere close to 500 rms each, but that's just from my experience.

 

Have any specs on the M100?

Phoenix Gold M series is nothing to mess with. I've seen them do some incredible output. Too bad there's not much out there like it today. I dunno what would hang with it at 100 watts on the market now. Even US amps seems to have gone downhill.

How clean the sound is plays way more importance then how many watts in determining how long the speaker will last. A speaker is only metal and foam, under normal conditions it will last forever. </TD></TR></TABLE>

i am told that the only way a speaker may kill itself is from thermal overloading or too much excursion. he also told me that a speaker can't distinguish between good power and bad power becuase a woofer will play whatever signal it receives. is he wrong?

wait..speakers are what cause the break-down? i didn't know that distortion was caused by an amp working to hard. i was udner the impression that amps are always creating distortion, hence the THD. maybe i'm mixing up with audible distortion that's above 3%.

thats what i did. my amp ran much cooler than the one before it.


can anyone confirmed the information above? perhaps vteg, nsxxtreme, rcurrely55, etc..when it comes to this kind of stuff..i'm completely pooped..

 

Not AGAIN!

I will sleep through this one.

Bahahaha!! Sorry, that was really funny...

But yeah...assuming all of the ratings are correct feeding a speaker rated to take 400w NOMINALLY (key word right there) 500w should be fine. You might shorten the life of the voice coil slightly. Remember that the amp is not always putting out its rated power - that's dependent on the type of music you're playing and how loud it's being played. If you listen loud, a slightly beefier amp can be beneficial in that it has more headroom and is lees likely to clip. This assumes equal rating methods (all manufacturers use different testing methods, so the results should be taken with a pinch of salt).

&lt;- has 200w to his sub and 35w to each of the rest of his speakers, and can't imagine needing more juice. O_O

A very common misconception. You were just clipping the amp so badly that you were sending DC to the woofers. They overheated and died. If you had had a bigger, better amp they would still be playing. It has nothing to do with this hidden "mad output". If the amp could put out bigger numbers, PG would say so so they would have a perceived advantage over other similarly priced amps.

No, they might not. I don't know the exact specs on that amp, but remember, alot of companies do this... the biggest of the underrated were always refered to as "cheater amps". Rated at 75 watts at 4 ohms, and shooting to 1200 watts at 1 ohm or .5 ohm, etc. Anyhow, what the key here is the speakers are rated for 1200 MAX... who cares?? The RMS of these subs are only around 300 watts rms.
Either you did have the gains on the amp or your radio up wayyy to much and clipped the amp, effectivly doubling or tripling the power output of the amp (the RMS power since now the useable peak of the signal is extended over a broader area) and burned them up. That or the amp was just putting out too much at 2 ohms and burned the VC's

 

1200W? With how much distortion? A clipping amp is far more likely to kill a speaker than an over-rated but unstressed one.

A speaker will play and signal it receives (or try to) and when it tries to play distortion from the amp is when the blow. He is not really wrong, just a bit off.</TD></TR></TABLE>

distortion doesn't fall under the "thermally" or "mechanically" category though. Manville, Dan, John, Matt, Ben, and the other guys told me that distortion doesn't blow speakers. they told me a speaker doesn't know what's "good" and whats "bad".

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Yes, all amps make some distortion but you should try to keep it as low as possible. When an amp is working hard it does make more distortion.
</TD></TR></TABLE>

it does make more distortion, but most amps at full power produce less than 2% THD. so should distortion in this case blow the speaker?

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Distortion WILL blow any speaker, I do not know of the exact number that it will blow at and I don't think anyone does because it depends on the speaker and the amp conditions. Like I said already...the speaker does not know the difference between "good" and "bad" and plays both the "good" and "bad" but the speaker is not designed to play the "bad" and that is what causes it to break apart (to blow). It is hard to blow a speaker "thermally" or "mechanically" because that would mean you are driving it well over its MAX watt range, But distortion on the other hand will blow the speaker at any watt level. Your Friends are wrong, sorry. Just try to keep distortion as low as possible and your speaker will last forever. Any other ???</TD></TR></TABLE> I think your friends need to talk with my friends . Your friends are wrong. We already went into this and some here are playing possum, they know more then they are letting on to. Distortion by itself does not blow speakers. Now if the distortion you are talking about is an amplifier that is clipping then this is a different story. Even still, it will only blow a speaker if the distorted output is over the rated power spec of the speaker.

o_rage_o nice to see you still post once in a while you should contact me I have something you might be able to use for your classes.

 

Distortion has a rather broad meaning - basically, it is any unwanted change to the signal. All audio components distort the signal somewhat. A "good" component simply damages the signal less than a "poor" one. Clipping is an extreme distortion, since it changes the signal vastly. So yes, distortion in sufficient quantities will damage your equipment (so any Sony amp should kill your speaker as soon as you turn it on ).

i hooked up my RE SE to my 14 watts MAX computer amp and it didn't blow (had the amp clipped, which means mucho distortion. i thought something was wrong with my sub, so i putted my idmax on there, yet did the same as the SE. then the stroker got its butt fed with the same 14 watts max...still it didn't blow. my E15K was up next, and i was surprised it didn't blow too! what gives?
