No free lunch

@lalitk -- of course, it’s been on the cards for quite some time. That’s why I said I have ’yet’ to meet a high efficiency speaker that I liked :)

But keep in mind that your Canterbury’s are in a whole different league when it comes to price and performance. I have listened to various Klipsch Heritage models (except LaScalas), Devore Orangutans, Tannoy Sterlings, and Tekton Double Impacts. They were all very very good speakers, and I have no doubt have their own fan base. Just didn't do enough for me to want to live with them long term.

I’m looking forward to hearing your setup when the time comes.

From Denver to the ocean
And I never met girls  ( speakers )who could sing so sweet
Like the angels that live in Houston”

simple question for the speaker engineers:

if the cone or parts of the cone are moving in the opposite direction of the input signal, would you call that distortion?

or a flavor ?

If the whole cone is not moving in unison there is distortion. Is that what you meant?
