I was trying to figure out what would be the best way to place panels in my room. I live in an attic and it's an irregular shaped room. How should I place the panels in the corners? Should I have the panels run flush on the walls leading to the corners or should I have the panels canted covering the corners. The walls are weird but I don't mind creating panels to match the shapes. I've also attached pics of my room.
I'm getting some genelec monitors and subwoofer - the 8340's and 7350. Respectively, should I get smaller size drivers or should I just just buy these? I understand that smaller drivers don't hide sound anomalies in the room its just size controls how apparent you may hear those anomalies.
I'm not sure I could help you analyze this room given its shape. What I can say is that the purpose of absorption is to 'make the walls disappear' as it were. Corners have a bigger buildup of bass so making those disappear is a big priority. You have a lot of corners so you need a lot of absorption - just as anyone does.
You also need some kind of reflection-free zone. Additionally, the various angles will create their own standing waves which must also be mitigated. Long story short, place thick treatment everywhere! If anything, it can be a bit thinner on the flat surfaces. Given that, you could sort of 'even out the shape' with insulation. What I mean is to create a usable rectangular space within that space and fill everything outside the boundary with insulation. That's probably the best you can do.
If you read all the stickeys and all Ethan's material you will find that with peaked ceilings, placing absorption across the corners in the ceiling as well as all the other corners it what is needed as well as RFZ panels a Hexspa also mentioned. Covering walls and ceilings is good too. So in short, absorption is the answer... don't be shy.

This is the book's text that goes with the photo:
One of the most common “odd”-shaped spaces to treat is an A-frame room with a low ceiling, such as an attic or a bonus room above a garage. Both have angled side walls, though all the usual principles still apply. Figure 21.24 shows such a space that’s been treated fully. Broadband absorbers hang below the ceiling to avoid the focusing that would otherwise occur, and the side-wall reflection points are likewise fully treated. Although the side walls are angled severely, the corners formed by each side wall and the front wall are still 90 degrees, and so benefit from bass traps straddling those corners. Those two front corner bass traps have reflective membranes, as does the partially hidden trap under the peak directly above the window. The remaining panels are all broadband, without a membrane, to absorb mid and high frequencies.
