Two grand pianos are "twinned" by the COMBI-CHASSIS {D} assemblage which conveys the sympathetic vibrations from one piano to the other; resonance of the second Piano is captured totally, without any perpendicular loss and accurately reflected by the TWINLID {A}; unimpaired reverberation is attained while the potential sonority is intensified to more than twofold; a homogeneous balance is established pertaining to the resonances of both pianos; indigenous disadvantages of halls or studios are converted into advantages with the versatile functions of a tractable JACKING SYSTEM {C} and a multi-purposed, variable ACOUSTICAL FLAP {B}, both of which induce precisely desired reflections of sonorities which are compiled and resonated via the "shell principle".
