I've got a pair of original D's. Bought them new in 1978. They will (can) absolutely shake your homes foundation! I had a pair of LaScalas and was always amazed at the difference in bass...the LaScalas would punch you in the chest but not go so deep...the D's would shake the foundation yet not punch you in the chest. My fix to that was cranking both up together!

Schlepped both pair of them off to college and had one of the more wild systems in my dorm
Seems the manual is available... I've got one scanned I can send if you ever need it. Though it's for the original, not the II.
They also came with a little plug you could swap out on the bottom if you wanted to biamp them. (I still have those too, though never used them)
One thing to note... my understanding and experience is, the woofers need new foam about every 10 years. I also understand that you can't get this done by EV anymore, though I've read here on this forum that there are others who can take care of that.
I really wish they used something different that didn't disintegrate like that.
Do the II's have the little light bulb tweeter protector in them?
There is a pair of D's currently on ebay, unless that is what you are buying. I must admit I've thought of nabbing them myself just to have another pair.
Good luck with them, post some pictures back here for us to see.
