Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Below we expound some of them further.

Machined From A Single Block
All Opus baskets are CNC machined from a single block of magnetically inert aluminium, meaning it cannot be reused for smaller pieces like midrange or tweeter.

Metronome Connectors
Metronome inspired connectors are designed, carved from brass thence nickel plated just for Opus. These connectors have been designed to offer the most coherent aesthetics whilst consuming the least amount of physical volume possible.

Thermally Superior Heat Dissipation
Five huge holes machined between the spider and magnet have been deigned to optimise airflow and voice coil heat dissipation.

Minimal Tolerances
The single piece basket has extreme tolerances to prevent any loss of performance on cone excursion.

Quintuple Mounting
Six 3 mm screw holes have been implemented upon the frame design, designed to allow for various placement orientations during installation.

Sinister Specifications
