How about Bob's new ALS speakers? It's only 5" wide and 5" depth, but about 7 feet tall, so very small foot print. You already have subs, so you won't need to pay for the subs that come with the ALS. It will play close to 110 +dB with the 350's (ALS can handle 120+ dB). It's dynamic as hell and soundstage and imaging are one of, if not, the best I've come across. You can dial in the speakers to your room because the crossover has controls for treble, midrange, and upper bass balance. Bob designed the ALS with 350's in mind.
