Chances are, this has been discussed already, but my searches aren't turning anything up. I have a pair of 12" speakers that I want to put into some homemade enclosures, to be used as stage monitors. Is there a formula that will tell me what dimensions I should use, to get the best sound, or doesn't it even matter since they're only monitors? It would be nice if I could build 'em so that they sit at about a 45-degree angle. Also, should they be ported and how do I wire them so they can be daisy-chained together? If one monitor is 8-ohms, and each of these is 8-ohms and I chain 'em together, isn't that a little more than a 21-ohm load*? That would be no good, eh? *8-ohms x 8-ohms x 8-ohms, divided by 8-ohms + 8-ohms + 8-ohms = total resistance in ohms (21.3), right?
