Gelcore cabinet construction reduces higher frequency cabinet noise. P2P (Point to Point) internal bracing stiffens the cabinet to minimise lower frequency vibrations..
Ground-up mid/bass and tweeter driver design for increased power handling. High-frequency driver is fully hermetically sealed and mechanically isolated (floating) from the front baffle to protect from internal resonances from the mid/bass driver..
Isolation suspension base eradicates unwanted external and internal vibrations. Crossover design is mounted on the isolation base, to minimise any microphonic pick up and away from electro-magnetic fields radiated by the drive units..
