A constant directivity cornerhorn doesn't suffer self-interference anomalies from nearest boundaries. So there is no need for flanking subs. Instead, you would want to setup the subwoofers as distributed subs, a little further from the mains and low-passed lower. That way they can smooth room modes at lower frequency.
