I wanted to add a 2nd speaker to a Dynamo HS-5 (stereo Neo Geo conversion) and I was wondering if anyone could tell me if this is the original speaker, what kind it is, and if it's shielded. I pulled it out of the cab, and I would assume it was original. It only had screws in 2 opposite corners (the power switch is the same way).


There were no wires attached when I pulled it out (but I tested it). The monitor is in excellent condition, and I was wondering...does the speaker being connected or not make a difference, magnetically? I wanted to reconnect it (right now the machine has an old stereo speaker laying on top of it hooked up...got it that way too) but I guess I wanted to make sure it's safe for the monitor.
Also, how important are matching speakers? I wanted to find another HS-5 speaker, for that old skool street fighterish sound, but I'm sure it would be easier to buy a new pair. I'm really dreading having to thread 2 screw for the new speaker in that tiny space. I could barely get this one out as it was (needed to, to wire & photograph).
