Hello,
I would recommend treating the room and not the speakers. If they are rear ported put some dampers behind the speakers on the wall. Build a frame with 1x4 or 1x6 wood boards. Hone Depot will cut them for you and put mineral wool insulation inside with some cheap fabric over the front. Home Depot sells Viagro burlap in the garden department for $10. When you can swing it get some GIK diffusers and/or bass traps for your room. Treat the room and not the speakers. You will be amazed by the results. YouTube has a bunch of DIY stuff. It works at about 65%-75%. Amazon sells panels for about $30-$40 per 2x2 panel. If you want to know what it will sound like look up near field listening. Pull your speakers out about 4’-6’ from back wall, put about 4’-6’ apart put a chair 5’-6’ in front of speakers. Take a listen. Please let your speakers breathe. Also, get your first reflection points covered too.
