Hi, Brent -<br>
<br>
Hm, this is interesting. I've purchased a $20 pair of computer <br>
speakers and have cut one off. Right now I'm playing a CD walkman <br>
through the other one, and I do notice occasionally the speaker will <br>
cough up little bursts of noise - not super frequent, but once or <br>
twice every few minutes or so. Is this the kind of behavior which I <br>
can expect from having chopped the other speaker off?<br>
<br>
thanks,<br>
<br>
