AR TSW 410 InformationDoes anyone have the technical information on the AR TSW410 speakers. I am restoring a pair and still trying to figure our why this model did not have a seperate cup for the 6.5quot; mid driver. I presume the 6.5quot; drives the larger 8quot; driver below a certain frequency- kinda like the Speakerlab Nestrovic did in their Super 7's. If somebody know I would appreciate it. I did look on the AR site but tyhe print was un-readable....
