Mid and high way externally mounting. The horns are fixed on a CNC machined beech flange. The drivers are compressed , with the horns, with a system of tie/rods and wood damping blocks.
The medium-high speaker system is suspended with very low resonance frequency suspension with a wood pylon system with calibrated springs, for complete decoupling from the vibrations coming from the woofer
Mid and high horns is damped with Dynamat extreme
Middle throat rework from casting defects
Woofer loading is completely revised, now all the box volume is used for loading the woofer. The type of loading is changed, from air suspension to a Aperiodic load . The advantages is a damped Z module at the resonance, and better low frequency performances.
The type of sound absorbent has changed
Internally Box reinforced with beech wood slats
Woofer reposition more distant from the side walls.
New CNC front panel
New assembly of the woofer : it is compressed with the front panel, through a system of longitudinal tie rods / pressers / dampers. The tie rods cross the entire loudspeaker giving an extreme rigidity to it.
Woofer damping with solid ebony
Woofer basket damping with Dynamat extreme.
The rear panel remains the same but with the aperiodic hole.
Elastically suspended crossover with very low resonance frequency suspension
External crossover point to point wired, on a bakelite support
Crossover coils in copper wire with very low series resistance . No electrolytic capacitors. P.I.O. military condenser in the signal path.
Twisted silver wire plated copper cable, with teflon isulator for internal wiring
