Speaker problems

[Arty]

So my left channel speaker sounds funny sometimes..mid speaker 5 inch across....it gets a different level of distoration. only way to fix is to play something BASS (dubstep) heavy, then it goes away for a few days...and ideas? im not exactly sure how to describe the sound that was coming from it.

argh, I can't remember the name of the free monitor (audio monitors) calibration software...I'd look it up but compy is down.

One of the reasons I own an apple product (I know yuk) specifically an iPhone, is because from the beginning apple on both the software/hardware level is still, for mobile, years ahead of android. Core-Midi, inter-app audio, WIST, Audiobus 2 etc...(mostly core midi) was baked into the API/SDK from the get. One of the most useful "apps" for all things audio is audio tools, which has a $400 hardware unit which works with the iPhone+a "for room measuring/calibration mic...but that's not needed for ur particular issue...seems to be something which could be determined by using a speaker line testing utility. These are screen shots from parts of the app which do that...I'd recommend searching the web for open source PC application which does similar tests:

Oh yeah (duh)

The PC utility is room wizard. Despite it being free, it's used by (pretty much) everyone in the industry. It's main use is for calibrating a mix/mastering room with acoustic treatment, i.e., finding 1st, 2nd reflections, standing waves and how to pinpoint The Big Problem, which is build up of lower frequencies in parts of the room where right angles converge (worst place ever to listen to speakers is there...parallel walls and corners). The utility is deep and has a lot of other stuff. It's always good to calibrate any speakers in any room anyways, otherwise your hearing wall-demons. A bit o/t...but, to get back on topic, first thing is to make sure the issue is the speaker only- use the speakers sans computer, hook them up to a discreet, aka no computer around, audio source (iPod, CD player/turntable etc). This way, it's easy to tell if the problem is comes from something driver/computer related. If it sounds a-ok without the computer, you know wherein the problem lies. It Sounds from ur description to be a speaker-issue (this cone, doing that) but, I gotta say, computers+audio+the os+player-codecs, have produced speaker problems which sound and act so close to speaker only damage.

There's gotta be myriad (free) programs for testing everything "speakery" for the PC..,I haven't looked for a few years too.
