Hey guys--my name is Peter. I'm new here--I found this forum after reading through Rod's book. I'm about to have a studio built in a room in my basement in Colorado (by a guy who I know has built at least ONE studio before shown here: http://windovertheearth.com/rooms.html), and I've been really going back and forth over Rod's book trying to find an answer, but have been unable to find one just yet. Wondering if some of you guys could maybe help? I'd sure appreciate it. I have a pre-construction meeting Monday and I still need to find an answer. My question (at least one of them) is this: I've roughly figured the cubic footage of the room to be 2,730 ft³ (W 17' 10" x L 17' 4" x 8' 10"), and this qualifies me as having--according to Rod's specs--what he calls a medium-sized room (p. 33 in the book). My goal is to build what he calls a "combo room." But it seems to me that the suggestions he gives for using ratios, etc. are only what he recommends for small rooms--i.e rooms under 2,000 cubic feet. What I'm trying to figure out is exactly how to deal with the room modes if my room is bigger than the suggested ratios. Are there other ratios I could use that better fit my dimensions? I know that later in the chapter about "putting it all together" he goes through an example--which is great--but I guess I've never found a concrete answer as to what exactly I should do with the room modes in my particular room. I can tell you that I think I understand his descriptions about isolation (a high requirement for me) well enough to be able to communicate what I want to the contractor--I just don't know what to tell him about dealing with the room modes if he doesn't really know what to do. Anyway. Thanks for any reply, guys.
