This may sound low Hi-Fi, but I just heard the Triangle Comete ES in my small den fairly close to the back wall driven by an old Marantz receiver and they sounded very good. They are a bookshelf or stand speaker that go down to 55 Htz and have a horn loaded tweeter and are front ported. They were very coherent top to bottom and sounded very natural. They seem very unfussy about placement and can now be had at a reasonable price.
