(OT) Adding a ribbon tweeter to my speakers?

[GM]

I just got them laying on top of the cabinets for now. (technically there's really no better place for them :/ )

Technically, there is, vertically oriented to the outside of the driver, i.e. mirror imaged speakers, then toe them in as required to get the desired blend and to reduce reflections off of side walls towards the listening position.
