Timing is a key factor to the level of acoustic problems you can get in a room. When a loudspeaker has a faster response you will have less acoustic limitations.
B&W is not the fastest and their older series are even rather slow compared to most speakers today. A subwoofer can be a good option, but again you still need a sibwoofer with a fast response. Choose always for a sealed subwoofer.
Even when a subwoofer has it's own roomacoustic measurment system, it is still not in phase with the front loudspeaker.
You need a system what is able to measure both speakees and subwoofer togheter. In that situation you will always be able to outperfrom any loudspeaker system for the same money without a subwoofer.
