Well now that the boy, has moved out it is time to reclaim the basement. I will post pictures of the area I'm going to use when I have a chance, since I have questions about how to lay some stuff out. My first question is, do I need to put drywall on the walls? Currently I just have studs and Roxul on the walls and I would like to just put some sort of sound absorbing product and fabric on the walls,if possible.

I now have another question, I want to wire the room for 11.4, but currently only have two subs, is it better to put both subs up front or one in the front and the other one in the rear? The room is 13.5x30 ft, however the room jogs in four ft for the last 7.5 ft of the room.

Here are two pictures of the space I will be converting. I know it isn't the perfect area, but it is what it is.

If anyone has any thoughts, I would be happy to hear them.

So, after doing some measuring and thinking, I feel that 2 rows will fit with two seats at ten feet and the second row on a riser at 17 feet. I currently have most of the equipment that I need, as originally everything was going in the living room. The equipment I have is a 16:9 106inch dropdown screen, a Epson 5020UB projector, and a Onkyo HTC470. The plan is once the room is done, I will upgrade the equipment over time. I will probably, do a DIY CIH screen first, but you never know.

Since my last post, we have pulled the last of the drywall down and pulled all the wires for a 11.4 sound system. We also have started to remove the stucco from the ceiling, which isn't very fun.

11.4 is pretty serious! Make sure nothing rattles!!!  I've had a theater with two Seaton Submersive F2 HP's, and my doors rattled at 14Hz.  If you've got four subs in your space, the bass can be amazingly smooth, but I would suggest testing for rattles each time you add something on hinges or or items screwed in.

I will just start with 7.2, as I will need to get a better amp and more speakers/subs. Also, I really need to upgrade my current speakers and subs. I figured if I was pulling wire, I might as well pull extra.

I'm currently building my suffits and trying to decide how deep my stage will be.

Both up front!

I'm just wondering how come both up front and not front and back or one on each side. I'm not trying to be rude, this is something I don't understand very well, so the more information the better

Cork is a good product for sound insulation.

For Sub placement see this link
http://www.audioholics.com/subwoofer-setup/multiple-subwoofer-setup-calibration-1
As far I have read that the ideal spot for 2 subs would be directly across from each other at the master listening position. But then again other listening positions would not get the full impact as much so from the bass. Where 2 subs up front will distribute the bass to all positions with a diminishing return the further away from the MLP. At least this is my interpretation and under qualified theory.

The best thing to do to determine subwoofer placement is to measure both options.  There is the free REW out there, but you also have to purchase a mic ( and I believe a mic preamp)--the best total package is probably a product called XTZ for around $300, I believe.  The tricky part is, you wouldn't get measurements that matter until the rest of the room is finished so the mixs can accurately capture your in-room response with the subs at both location.  One in front and one in back at the midpoints of the wall will likely give you the most even response, but both subwoofers up front is a popular choice that can generally be Equalized to flatness, although the less EQ, the better!  Do you plan on hiding your subs, or having them in the room.  The former will make measurements more difficult since you'd need to plan for them in the build, but the latter would give you more flexibility.

I have read the REW HDMI and USB mic thread and think I will be going with this, however my laptop has just crapped out on me, so I will get a cheap laptop with HDMI after Christmas. Since I have wired the room for four sub locations, I will be able to test most configurations.
