The more the merrier for "an earth-shaking experience in bass realism" and close to the earlier KL-777 and KL-7090 firing squads
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.
AlNiCo-driven mylar cone cap driver with 200µ aluminium deposit, corrugated edge, aluminium bobbin and long voice-coil.
Mylar horn with Kenwood equalizer very near the mylar film for better high range response.
Pair of AlNiCo driven cones with diffusers for wide-angle dispersion.
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 !
