Best Lowther Driver For Oris 150? (BD-Design)

Hi Bert (and everyone else),

I'm considering purchasing Lowther drivers for my Oris 150's and was wondering what driver would be considered optimal for them? I'd probably like to go with 16 ohm drivers because I'll be using tube amplification. I know folks have experience with AER drivers but they're simply too expensive.

Any suggestions?

Also, do the clear phase plugs work with the Lowther drivers?

Thanks,

George
