The SUBGRAPH base, derived from the METAGRAPH, has a more minimal static cross-section and is therefore more acoustically challenging. Its upper and lower sides feature differentiated patterns in depth, which acoustically trim the non-retaining support base (no fixation). This design optimizes the spectral balance, contrasting finely detailed highs with an immediate, deeper bass.
The SUBGRAPH is available in three versions, each of which, compared to the standard version (pure copper), influences its sonic characteristics in two extreme directions through the use of different materials. Pure Grade 2 titanium produces shorter and faster transients than pure copper, while pure tungsten has the opposite effect of titanium and, in particular, shapes the bass range differently – significantly extending it downward. GRAND ANALOG ELECTRICS takes a critical view of hybrid materials such as Exium AM in terms of sustainability, as true closed-loop-recycling is generally not possible here; instead, only downcycling occurs.
