What are the 'Family of Curves"?
The family of curves is made up of amplitude response measurements taken in a sphere around the speaker in an anechoic environment. The performance you hear in your room is a summation of this family of curves in varying degrees of weighting.
In the design of each Bryston speaker we begin with anywhere from 120 to 300 measurements depending on the size of the speaker. From there each curve is considered both individually and as groups with particular algorithms applied to each curve in the group and then each group against the whole.
From this collection of measurements we published the Bryston Listening Window and Sound Power curves for each product.

PS - I sent Ivan a pic of a sample of this measurement so he can post it.
