Quoted from gdonovan:
Question for those that have experimented; any thoughts on a set of replacement 4 x 10 speakers for Pre-DMD Data East? I just tried some generic 4 x 10's and they were horrible. Just looking for a set comparable to the originals, I have one that has the slightest buzz and its irritating.
The buzz isn't usually because of the speakers, it's because of poor grounding on Data East machines. Some are much worse than others. I would look into the threads there first. That being said, I just did a speaker swap on a newer DE (Tommy) over the weekend. Huge difference but a few things to note. Get 4 Ohm speakers, if you crank the sound up a lot, you may need a separate amp to push to the speakers. This can get complicated, I am not familiar with the older DEs to help there. But if you do a seperate amp, you will likely get rid of all the hum as well.
