Top quality front channel theatre speaker, hidden in the ceiling. Unlike other in-ceiling speakers this is a dedicated for home theatre. These are priced per pair The Atlantic Technology ICTS-6 HT uses a heavy-duty 6 ½-inch woofer that is angled 15 degrees towards the listening area, and Atlantic’s exclusive 1″ Low Resonance Tweeter that handles more of the sound spectrum than any other in-ceiling speaker for unmatched sound coverage. Front mounted Boundary Compensation and Tweeter level controls ensure ideal sound wherever they’re mounted. The unique Boundary Compensation Control reduces the undesirable build-up of mid-bass frequencies when the speaker is placed too close to a side wall.
