If you had a woofer, then there is flexibility of watching movies with it.

I dont have both speaker but I do have the older S2000 and S730. Bought S2000 and I was very happy with it when I was listening to chinese/country song a lot. Vocals stands out especially. After years, now I start to pick up kpop and S2000 is definitely lacking. It is also lacking when watching movies with lots of bass. I got the chance to pick up S730 for just RM850 at edifier warehousesale 2 years ago. Really enjoy it for movies and kpop.

But it also depends on your usage. I was looking to fill my living room thus the S730 fits the bill. It was overpowering when I tried it in a small room and when you turned the volume down, it just does not shine.

I would personally advice against R2700/2800. Bought one before and sold it a year later. My personal opinion... its probably more suited to studio use than personal usage.
