The VI300 will be totally fine even without having the subwoofer. To me it had more impact adding the rears rather than the sub(more immersive experience, it brings you more into the movie), so i guess you should definately give it a shot. You can add the sub at a later point if you have the spare or think it would be a nice addition.

Great advice from the other members here. The Surround Speakers will enhance your experience with the addition of the rear channels. There is no need to also have either the Bass Module 500 or Bass module 700, unless of course you decide on more bass and low frequency sound!

Thank you for your response. I didn't think that we needed the seperate bass to get good results from rear speakers for the Soundtouch 300 sound bar. Just need to go out and buy them in white!
