Designed as the ultimate real-world reference speaker system.  No bi-amping or bi-wiring required. With high sensitivity and full power response available over eleven octaves, the Grand SLAMM had no serious peers (exluding Wilson Audio's WAMM Series 7). Its more compact footprint allowed placement in environments where a WAMM couldn't work. Designed for use in the most demanding music and video systems in domestic rooms and control studios.
