I heard the References, 2+ and the 7s. Family resemblance was good.
I don't think the Hsu sub would be a good match in your room and layout.
IMO, the key to great imaging with a sub is to have good phase linearity for seamless integration. Without a crossover to roll the lows out of the 7s, a continuous phase control on the sub and freedom to place optimally, it's well nigh impossible.
Additionally, the LF processing maybe playing havoc with the 2ch playback.
