**FEATURES**

-   Gelcore™ cabinet construction reduces higher frequency cabinet noise.
-   Isolation suspension base eradicates unwanted external and internal vibrations.
-   The driver assembly is mounted to the front aluminium baffle by pretensioned studs to give the correct acoustic seal, while dampen vibrations and minimise structural coupling of the assembly in main cabinet.
-   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.
-   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.
