Success story. I ended up getting the speaker off of ebay (link to speaker information in previous post.) I cut the ears off and it fit perfectly into the existing opening underneath the operators seat. I noticed the edge of the speaker was being pinched and restricted of free movement against the black plastic housing. I used a dremel and cut an angle at the 4 areas i have circled in red. This allowed the speaker's edge not to touch the black plastic housing. I believe that was part of the cause for the original speaker to fail. The other part was the original speaker being 4ohm and it should be at least 8ohm according to my sound card's manual at the voltage I'm running it as.
The new pair of speakers i received don't seem to have any strength of magnet.?? Whereas the original speaker's magnet was quite present. Not sure how speakers work but I thought all speakers need magnet?? Regardless, the sound quality is more or less the same as the original.
