For on-wall and in-wall versions of SoundFrame 1 and its ‘centre-channel’ version SoundFrame 2, we’ve utilised our most advanced driver technologies to raise the quality of on-wall speaker performance. Both employ true 3-way full-range driver configurations featuring a pivoting Inverted Dual Concentric (IDC®) 4-inch mid-range/1-inch tweeter module and a 6.5-inch C-CAM® bass driver. The innovative IDC module is able to pivot in all directions allowing you precisely to direct crucial frequencies toward the listening area for greater detail, imaging and fidelity. At the same time sound is directed away from room boundaries, eliminating the unnecessary reflections that can cloud performance. The drivers, including the large high-power bass speaker, feature advanced RST® cone technology, developed by Monitor Audio for our flagship speakers. RST’s surface topology adds rigidity and strength but keeps the cone light and agile for a super-fast life-like response.
