Unfortunately, I have not been able to find a pair of these to audition, but every review I've read of them has been very positive. Having owned many different PSB's in the past & present, I would likely buy these without even auditioning them. I still love my Stratus Golds and would not trade them for anything.
I have my Stratus Golds in a room similar to yours as my house is open concept. They fill the space very nicely, but they need some decent amplification to do so. I suspect the Synchrony One's would as well, so make sure you run a decent amp.
