Is the rock wool panel same as the ceiling tile (usually come with 2'x4')typically used for false ceiling which I see in the most business or company office? Can I use this or the plywood as a backing? I think most Lowe or Home Depot carry these types.
I asked couple of store around my place (even the acoustic store), but they do not know what I am talking about.
Where can I buy these or the Owens Corning products via the mail order? Thanks

Ceiling tiles are not suitable as substitutes for the OC 700 series or the rock wool panels.
The OC 700 series should be able to be ordered from just about any commercial building supplier who deals in Owens Corning products. If you ask them to add this on to there regular order, and wait for it, this should avoid any special order fees, minimums (you do have to buy an entire box of panels), etc.
As Batman mentions, John Mansvile Spin-Glass is also a suitable subtitute, but look for the equivalent density as the recommended OC 700 series panels, the JM dealer should be able to cross-reference them.
Both companies have web sites, and data on the products. Do not try to call and ask about the OC "made for acoustic room treatment" decorator panels, these are outrageously expensive, even more than Pro-foam, etc.

  John,
  Please don't take this the wrong way. I like your input and respect your work. But you struck a nerve. J-M is Johns-Manville, not John Mansville. Two guys, not one named John were the founders. My Dad worked 43 years for them and that would make him turn over in his grave (what's that rotating sound in the distance?)
  OK, I said my piece. Please carry on with your good advice.

      Thank You. You are a gentleman, and I shall toast you next time I hoist one.

The rock wool which Jon refers to is not the suspended ceiling panels you see in offices. It is a composite made of spun glass fibers suspended in a resin which gives it a semi-rigid consitency.
I have used Johns-Mannesville spin-glas boards which are the equivalent of the Owens Corning sheet rock product. I was able to buy them from a local insulation supply house which I located from the JM web page. A package of 6 4 x8 sheets of two-inch thick unfaced panels cost me about 70 bux. Hope this helps
