Array speakers & OTL

OTL

The first commercial OTL's came with special high impedance speakers...

Guess it must be possible to make up an array to simulate a 'high-impedance' speaker, but you may lose imaging/spectral position by using lots of speakers, so you may end up with a worse sound than just using a 'conventional' OTL, and a good conventional and sensitive speaker set up....
