You can get awesome sound in a small room. I would keep the sub out til you get a reference. I know its hard to not use gear you paid for but you really should listen without it first. Play around with speaker poasitioning ALOT when (if) you bring the sub in, make sure it makes a real, seemless improvement.
small room questions
i will soon have a dedicated room for my audio and was wondering if it is possible to get good sound in a 10'x 11' room. i currently have a set of sonus faber toy monitors on stands and a rel t2 sub. the room will be completely bare other then a chair, audio rack, and audio equipment. i have about $600 i can spend on treatments. i have read about setting the speakers diagonally in the room to help cancel room nodes, but dont really know where you would put the sub. anybody been able to tackle a small room with success??
