Graham SYSTEM3D 4 way 3 x 10″ woofer 4 box (pair)

Developed originally for the Royal Opera House, the SYSTEM3D offers the same neutrality and transparency as our BBC-licensed loudspeakers, but at much higher sound pressure levels.  The full system consists of a pair of speakers each with 2 driver sub cabinet handling frequencies up to 180 HZ which then crosses over to the 3 way top box.
