If you leave the room config'd in that manner, as Craig said, a totally absorptive rear surface behind you is essential. Also, I'd space the surrounds farther away,...equidistant yet further away. Like in the corner above the PC monitor, and in the other corner above the CRT (I too have a retro gaming 4:3 40" HD Sony CRT,...stunning pic to this day,...but ~300lbs or so).
The measurements will enable you to better optimize the sub/room interface. Also, the sub/mains interface,....without measuring capability, you're flying blind. Knocking down any excess room energy in the subwoofer operating range can save all important amp headroom, also help smooth response significantly. You'll be able to assure the mains and sub are playing nicely, not destructively.
I'd consider some 4" thick SBIR absorbers behind
the mains/center, and bring the center as forward as possible to mitigate any diffration, or negative interaction from the stuff surrounding all that. Ideally, the center, which carries so much of the load these days, should be identical to the mains in every way,....physically and acoustically. The immediate surroundings around the center should be wide open, or total absorption. So much of it's energy is radiated in directions other than straight ahead. This energy needs to be attenuated,...not reflected back at the listener resulting in a smeared blend of direct and reflected.
Sure, I've left out/forgot stuff,...however you've got to begin somewhere,.... BTW; nice system to begin with, you're farther along than the vast majority that seek this type of advice,...so good lookin' out.
Best of luck

Thanks for the wise words, man!
So you agree, (aside from maybe a bigger television
)that acoustic paneling is my next logical step?
The mains are probably a good 7" off the TV wall. They've got 2 ports each in the back, and read plenty about giving them breathing room.
The room pretty much needs to stay that way as of now, since it's designed that way. The cable comes out of the TV wall, and well, I just painted 2 days ago and made that wall chocolate already ;p . When you and Craig say an absorptive surface behind me, do you mean above the couch pressed against the wall?
Good thinking on the surround placement. I've been noticing that I was having a small surround sound-stage lately, but couldn't put my finger on it. I'll have to look into some speaker mounts.
Regarding the WEGA - YES! CRTs are the only type of television to accurately reproduce SD content from retro consoles. (Aside from an XRGB) Luckily my Grandmother had this lying around so I've got my Master System, SNES, Dreamcast, and Saturn plugged into it via SCART RGB Splitter to YUV component converter box. Looks outstanding. That was last year's project...
When you say 'knocking down excess room energy', does that mean the acoustic paneling?
Would the panels be installed behind, and above the mains as well as above the couch? Does it matter if they're directly behind the speaker or higher up on the wall?
Thanks for the compliment. I'm a computer guy but have always been into HT and music. I'm going from project to project lately upgrading a bunch of stuff and finally decided to move on from HTiB type systems and get something worthy. I'm glad you like it!
