I recently attended a T5 demo which used the new MS05 speaker set, and included a pretty loud demonstration of the concert organ.

This was to about 25 peaple, and the entire demo was peformed only using the MS05 system, no other PA or amplification used. For home use I'd give it a listen. I'd heard the preceding MS04 system at previous events and been somewhat unimpressed but the MS05 sounded much better.
