i will be the first to bite.. but i dont have the answer to all your questions.
1- i have no idea what you mean by "what kind" of internal wiring? you may need to clarify that.
2- i am not sure what you mean by "inert" either?
3- spiked? do you mean have spikes on bottom.. yes and no. they send you both spikes and rubber knobs that you can put on depending on if you have carpet or hardwood floors.
4- drivers are NOT made in house. i believe they are purchased from over seas. but the cabinets and build process, all happen at the factory.
hope that helps.. BTW- the 60's are awesome speakers.. i have a pair myself. tremendous detail, even at incredibally loud volumes.. and very precise and clean sounding. and very beautiful to look at.
