I had a thought but I'm not able to
Verify it completely by my own so A quaestion to James:
If we add an active crossover like the one used in the model T.
Maybe two way designe between the Bryston pre and the amp,
And it tune to the Mini T's exact low pass corssover point ...so we cancel one slop
Cossing power losses and cancel unwanted too high frequencies on the bass driver...and
Too Low frequencies on the mid driver and by so get an half active speaker which may turn
More resolute in the lower mid??

I guess one with both speakers model T signature and mini T can experiment
If it's worth looking further into

Of corse then we need two amps to drive the mini T's and a half signature

Thanks
