Hi Andrew,

They weigh about 45 Kg a piece.

And yes, they are really dead! No reseonances at al...

This does inflict the sound; less "warmth" because of absence of colouring thruogh housing-resonance. This must then be compensated by the filtering. Yet, the truefull midrange is worth all the trouble.

Greetings,

Lucas.
