Yeah baby....I found a mate

Actually Tannoy and other companies should have followed the B&W example and used multiple moderate-sized drivers on their larger speakers rather than a single or double 15", precisely so as to avoid this.

B & W noticed the same laws of physics that you didn't pick up on and went with smaller drivers.

Are you sure B & W didn't go with multiple smaller drivers to avoid massive cabinets? Compare the cabinets of the 801 Matrix and Nautilus iterations.

Analogbass,,,I think you are just better versed in the old fashioned folkore...there is more to this issue of just a driver having more mass....

Some good info in this white paper.

Jack, you know as well as the rest of us that analogbass will completely ignore real physics in lieu of some subjective psuedo-science with unprovable claims of sonic superiority.
