How is the clipped portion of the wave not dc? Isn't it caused by the fets being fully opened and thus outputting the rail voltage to the speaker?

NO.. it causes an oscillation of harmonics related to and on top of the fundamental frequency... The fets are not 'wide open' and there is no DC...

I have a basic understanding of the fundamental frequency but haven't covered it in school yet so I guess I can't argue with you //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

^ That's OK.. I encourage you to look into the facts for yourself..

I encourage you to do the same.

Audio signals contain no DC elements. If the capacitors can pass it or filter it, it's not DC.

What does DC sound like? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Electrical signals are NOT "audio signals". The only time there is an "audio signal" is when a speaker converts the electrical energy into sound by movement.

Capacitors can most certainly pass DC signals. Is not the electricity coming from the car battery DC? I think so. Can you not put a capacitor on it and DC current continue to flow through it? I think so.

So wait, DBfan knows about car audio? WTF?

^ you clearly have no idea what you are talking about, and I'm sure what you just posted may be part of the reason you are so ignorent.. (looks like someone's windows paint project)

Actually, it's a graph from True RTA. I added the lines, arrows, and text using Visio.

Apparently even MSPaint is something you don't understand.

Forget everything else.. A clipped signal has no DC component in any conventional sense..
Of course you claim to have worked for someone or another as an 'amp inspector' so you must be right.. lol..

Never heard of Peavey? Really? And you want to pretend to be some sort of "expert" in the audio realm? Please...

I spent several years at Peavey's amp facility as an Inspector/Testor (official title) in Meridian, MS (which is where I got the bulk of my electronics training). I also worked a little while in the Mixer shop testing the small cabinet mixers, and a short stint, as a lacky, in the Guitar Shop (when I first started). After that I have spent 12 years (5 on active duty, and 7 as a reservist) in the US Navy as an Electronics Technician (please tell me you know what the US Navy is). Since getting off active duty, I have spent the last 7 years as a Systems Administrator for a well known IT company (I wont say the name to cover my own butt). I think I've got enough background and training to speak for myself, TYVM.

If you check out Rod Elliot's site (who really is a master of all things audio) there is a very interesting read on how asymmetrical AC signals can produce what can be considered DC current with a solid state amp...

i think you just have to be smarter than the box the sub came in and you will be fine lol. used properly a speaker will likely dry rot before it quits working. there are variables though.

one thing i do notice though is that old speakers dont seem to be able to handle as much power as they once did. would weakening magnets have any affect on this? basically causing the driver to exceed mechanical limits more easily?

 

[putergod 10+ year member]

I would think it would be due more to the fatigue of the voice coil over time. However, everything degrades over time, so even the magnet will lose some of its magnetism.

First you argue with me, stating there is no DC in a clipped signal, then you post a website to "check out", and admit that in your own opinion, the writer is the master of all audio, which supports my argument that a clipped signal does INDEED induce DC current. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Your magnets arn't losing flux.. your driver's suspension has been worked in to the point where it is worn out..

PM me if you want recones !!

That too... but that will make the speaker sound poor (muddy, uncontrolled), and increases the possibility of over extending and/or bottoming out more than anything else.

Capacitors can most certainly pass DC signals.

This here pretty much explains that you have no idea what you are talking about...
