I am about to purchase a Boston Aacoustics XB4 for a fairly small room. I am matching this up with a set of VR2's, a VRC,and VRX,s powered by a dennon AVR987. If I was to move to a larger space can I just add another sub or should I purchase the bigger sub at this stage. I was told that having two can better distribute the bass throughout the room.
Thanks
