Do you have a second system or a computer speaker set-up that would benefit from the CHT8?

On lighter side, perhaps the LFM-1 can be put in the system to handle the the normal combination of low-bass tasks, while the CHT8 can be set up as a LFE only sub and be placed immediately under/behind/next-to the primary seating sofa/chairs ... give the movie viewer that little extra bit of "tactile involvement" in some scenes, as long as it doesn't conflict with what you would be hearing from the LFM-1 and the rest of the system.
