I currently own a Klipsch R-4B reference soundbar setup. It has a wireless subwoofer that is 6.5 in and right now just isn't enough for what I would like. I was wondering, is it possible to replace the sub it came with, with another? First, is it possible to use another brands subwoofer with some sort of wireless adapter? If not are there any other subs from klipsch that I could buy besides the R-10SWI and R-12SWI? The two wireless sub options from klipsch are a little out of my price range. I did notice that some of the other soundbars klipsch sells have larger, nicer subwoofers included in the setup, but can you buy these seperate from those full setups? Thanks for your reply!
