A high dynamic range audio speaker.
The mesh grill cover was created using the V3's Flow tool on a revolved surface.
The main rendering was done in Kerkythea 2008 Echo Boost Beta (64 bit) - Metropolis Light Transport (BPT) at 250 passes. (12 Hr)
The second rendering which really shows the detail in the metal mesh is by Ed Ferguson done in KeyShot (Thanks!)
