The more the merrier for "an earth-shaking experience in bass realism" and close to the earlier KL-777 and KL-7090 firing squads
Woofer :
Aluminium voice coil bobbins for better heat dissipation and power handling, perforated woofer cone cap, cone made of NBKP and canadian pulp for less breakup, long voice coils for linearity, a special acoustic filter in the bass-reflex port made of rolled & corrugated PVC which prevents standing waves.
Low-Mid :
AlNiCo-driven mylar cone cap driver with 200µ aluminium deposit, corrugated edge, aluminium bobbin and long voice-coil.
High-mid :
Mylar horn with Kenwood equalizer very near the mylar film for better high range response.
High :
Pair of AlNiCo driven cones with diffusers for wide-angle dispersion.
Super-high :
Aluminium-coated mylar film with AlNiCo magnet.
Firing-squad or not, not many of today's high-end speakers have that much AlNiCo in them !
