Hey guys,

Got a problem brewing here. I'm trying to figure out the problem with my two front speakers. They both seem to output the same, yet, my right speaker's woofer output is far greater than my left tower.

The odd thing is that there is no sign of physical damage and the speaker on my left is certainly not blown because there is still sound coming from the speaker, just less power (or so it would seem). No hiss, no distortion - just less "sound".

I've reset everything to default, switched cables around and the problem still persists.

There have been no adjustments to balance whatsoever made.

My setup:
-Polk RTi8 Towers
-Yamaha 5750S Receiver

Help me Obi-Wan Kenobi! You're our only hope!

Shit, I think I've figured out my problem.

When I push in the woofer on my right tower speaker, it scrapes against something.

Not good.

Take out the driver and see what it is

Are they ported speakers? If they are (I'm not familiar with Polk) and the port is near a wall or other object, then this could be boosting what you hear from that speaker.

You could have poped one of the drivers, which means it's essentially ruined.

A speaker works by having a very thin hollow tube wrapped in coil (called the Voice Coil, making an electro magnet) slide over a cylinder which is surrounded by a large magnet. The differing flows of current move the voice coil in different directions and amounts.

If you have them turned up insanely loud you can cause the tube to jump off the magnet (or guide) and go back on crooked, essentially fucking it.

Typically the suspension doesn't allow the diaphragm & voice coil enough travel for this to happen (in modern speakers anyway). Having them turned louder than they like will usually ruin them either way.

Eitherway, your voice coil is damaged.

That sounds about right.

They are still under a 5-year parts and labour warranty so I figure I'm safe, unless they say something completely retarded like "defects only".
