Small room big dip 8340a + 7350/7360? - Forum

Dear all,

I have a small far from ideal bedroom studio (2,5x4 m, roughly L shaped (the room is 3 meters wide halfway) with 8340a monitors. I sit at the narrow part of the room (2,5 meter wide) . I have gik basstraps in the corners Behind the desk and have spare acoustic panels from my previous studio on the wall behind the desk. My Genelecs + glm are a big upgrade from my Alesis M1 MKII (I had a peak at 120hz and I have way less ear fatigue since I upgraded) but the room response is pretty awful. Unfortunately I am stuck in this situation meaning I cannot place any more acoustic panels. My biggest issue is a big 15db dip around 85 hz and other dips at 7-10 db dips at appr. 160 and 250 hz (see attachment). The dip at 85 bothers me the most though for my (edm) music style . I always learned that subs are a nono in small rooms, but after some research I read here and here that I could diminish this with the help of a sub and/or moving the speakers into the wall. So I was wondering if a 7350 or 7360 would help with the 85hz dip (the other dips are outside the range of the sub unfortunately). I would prefer the 7350 because of it's size and budget but seemingly they don't match bass response with the 8340. Yet I am willing to buy the 7360 if that would help me diminish that dip, although I do realise I am not able to fully enjoy the 7360 in this small room and would probably even need to lo lo cut/shelve it to prevent issues on the lower frequencies. However, thanks to GLM I might even enjoy some bass extension too. The main idea is to keep the headroom in my DAW, let the sub turn dips into peaks and let GLM manage any other peaks that might occur. Somewhere down the line I will move to a bigger room, but for the coming 5-10 years this is what I have to work with. 

So what do you think. Is it worth to try a sub. Would a 7350 suffice if it's just about the low dip at 85 hz ? If not, what are the chances the the 7360 will help. I realise I will have to experiment in my specific situation, but since it is my bedroom too I have little flexibility for the placement of the sub (I cannot place it on the far half of the room). Also how much would speaker placement help for the other dips at 160/250 400/500. Right now I sometimes put and eq with a few peaks on the master, but 18db is a bit much and eats up all my headroom, but mostly I prefer to let my ears get used to the room (they already are) and listen all my reference tracks and casual music within the room's limitations. 

Oh and 2 x 7360 is definitely out of my budget, 2x 7350 is an option.
