If I remember rightly the WHF team are doing a feature on the Yamaha soundbars in the next issue. I am sure the team will correct me if I am wrong.
The soundbars are a great alternative if you haven't got the room for a full system, should fit under the tele or on a shelf.
I couldn't see the picture of your cabinert, so cannot tell what space you have.
I will try again when I get home, it may just be a work thing.
