But they will be wrong. While model B uses 8" woofer, model S uses 8" SUBwoofer. Also Vantage B lacks front firing woofers. I bet You are asking why model B was even born then if we have model S with more drivers? The answer is simple - Model B is much closer to point source and is devoted for environments where listening distance is critically short and one still seeks full scale full band performance."
