Just moved, need to treat my new space for mixing/tracking

With the help of this forum I treated my music room with 7 DIY acoustic panels in my old house several months ago. Well, we've since had to move, and I now have a new (and probably less conducive) space I need to treat with the 7 panels. This time I'm in a wide open unfinished basement. The nice part is the walls have all been treated with insulation with a thick vinyl covering to hold it in, but it's one large room so I think I'll get limited returns with whatever I do. The space overall sounds pretty dead in general cause of the insulation, but I want to use my existing 7 panels to maximize the potential of creating a workable mixing environment. So far I'm thinking of doing 4 panels, 2 hi in each corner (like in the picture), hanging 2 more on the side walls at first reflection points, and suspending the final panel from the ceiling above me and the monitors. Would this be a good approach? might I not need first reflection panels given that it's bouncing off the insulation anyway? I'm thinking the ceiling is the worst part here, but also sure the size of the room behind me is detrimental. Ideally I'd get 3 more panels on wheels to put behind me and block off a portion of the room but don't have the funds to do that yet. Anyway, just wanting to maximize the panels I have to create the best possible environment. Here's a couple pics: Front view: Back view (it's a mess, still not moved in):

anyone?

Bigger rooms usually sound better, acoustically, so that might not be the case. However, the ceiling looks pretty low, so you might have an issue there.

If it already sounds dead then you probably don't need more absorption. It looks like all the walls have deep insulation on them, so you might be over-treated. I would suggest that you download and run REW on your room, and see what it shows. It might turn out that you need less absorption (ie, cover some of that with reflective surfaces, or better placement of absorption. REW will help to determine that. - Stuart -

Cool, thanks for the reply. I'll try and get the REW setup running. I did do my first mix down there and the low mids came out pretty muddy when referencing. Could that be the result of too much bass absorption? Like I mentioned there's insulation behind the white covering on all walls.

Could that be the result of too much bass absorption?

If it is in the low mids, then it is probably lack of enough bass trapping (small rooms need a LOT of bass trapping) and too much absorption in the mids and highs. You say that the insulation is covered with some sort of "thick vinyl", so that is probably reflecting back some of the highs, and it is mostly the mids that are being absorbed. REW will help to reveal if that is the case, but that's what I would expect, from what you say. - Stuart -
