Hiya, I have the 30D that compliments 37 inch TV and below and is therefore smaller than the YSP 1100 model. The YSP 1100 has now been supeseeded by the 40D model (same size) and is suitable for 40 inches and above. The later model have DAB Tuners and can work with Vierra/Panasonic remotes and have the relevant HDMI connections whereas the older versions do not. However I have heard the 1100 and it still has an impressive sound and is a lot cheaper than the newer models. I have a Subwoofer with mine hidden under a coffee table. Marantz also do a good soundbar but is expensive. It just depends what you want and what you are willing to pay. If you go the Yamaha website they go into greater detail and if you search for Soundbar or sound projector on this Forum will give you some relevant info.
