CRYSTAL
The Crystal Crystalline structures exist throughout nature and often exhibit immense beauty. But even the most sought after of all precious gems, the diamond, first needs to be formed from common carbon under extremes of temperature and pressure, then cleft, cut and polished before its beauty is fully realised.
The Crystal series from Wharfedale now introduces a new generation of drive units. Simple polymers formed into complex matrices under high temperatures and pressures to produce something altogether more brilliant.
