And your hesitation is?
Based on your original post, my recommendation would be to acquire room analyzing capability. Download a freeware copy of REW, purchase a measuring microphone and learn how to measure your room so what ever your choice in subwoofers might be, having room measuring capability will allow you to integrate the subwoofer system into your room's acoustics.
Placement of subwoofers is based on how well a subwoofer system integrates with a room's acoustics. There is no placing subwoofers based on one's sense of aesthetics and then expecting to get the best performance out of their subwoofer system. Subwoofers are like cats, if you're going get along with them, you'll understands, other then on furniture and counter tops or tables, if you expect to be successful in getting along with them, they go where they want, not where you want.
Without room measuring capability, there is no hope. One cannot be a sound quality type of guy and then post things like: "I'm limited to screen wall placement and am wired for duals just on either side of the center but could use the Rythmik F25 under my center channel laying on its side."
If one wants sound quality, they're going have to be more flexible then the above indicates. If one is interested in sound quality, the issue is going have to be further explored. In the end, it's all about the Benjamins and how many of them one has to throw at this type of problem.
