SE-Raider,I don't see anything else on the TC Sounds site that references the individual components (midbass and full length ribbon) mentioned on the line array overview. TC Sounds may be an OEM to some other company vs. offereing these parts to the DIY market. It is hard to be encouraged about availability of these parts for DIY use at this point.

PS. You need to come see me again. Upgraded digital active crossover for the near field arrays--much better sounding--and a new Jordan JX92S with a ribbon MLTL.
