I doubt raising the speakers will do much but it's worth a try.
I've got no personal experience with foam traps/panels. Initially I made some DIY traps and panels from polyester and polyester/wool insulation batting but I eventually replaced them with RealTraps which are fibreglass. A friend has some foam corner wedges and tiles in his room and they certainly have helped but I'm not certain that foam is as effective as the fibreglass in the RealTraps which I certainly found more effective than my DIY efforts. The foam tiles are intended to be glued to the walls and that means that they will be less effective than an equivalent product placed out from the wall a bit so there's an air space behind them. Actually mounting any absorber directly on the wall without an air space behind it reduces effectiveness but it does save on space. If you have to go that way, the best you can do is to go for the thickest panel you can since thickness improves efficiency also.
A bit over a year ago I experimented a little with some dense cotton insulation batts intended for use in soundproofing HT rooms. They seemed more effective to me than the normal rather fluffy polyester and polyester/wool batts I had used in my earlier DIY efforts. The polyester and polyester/wool batts were lower in density and needed to be compressed in order to achieve good results at bass frequencies. The dense cotton batts were at least equal in density to my polyester batts after I had compressed them and delivered quite reasonable results but they were also about 3 times as expensive as the polyester and polyester/wool batts which I wasn't compressing to one third of their volume so they were a more expensive option than the polyester batts in some ways.
My preference so far is for the fibreglass but while I was happy to buy a finished fibreglass product, I wasn't prepared to build my own using fibreglass simply because of my concerns about fibre release during the building process. Fibreglass may not be a carcinogen but it can cause skin and breathing problems via contact and inhalation and does require safety precautions while working with it. Unless you can take those precautions I would be cautious about using it, especially if you have small children in the house since any fibres and dust released will end up on the floor where they can be trapped in carpets until released when they're disturbed. Children play close to the floor so any fibres/dust released by that play will be in their breathing zone and more likely to be inhaled, and skin contact can result in rashes. Many will say I'm being over cautious but I used to work in the health and safety area and I do have concerns about exposing others to risks when I'm doing something I want to do.
