This is the owner's manual and warranty for CWM LCR7.
This Owner’s Manual introduces the Bowers & Wilkins CWM LCR7 in‑wall speakers, explains the five‑year limited warranty (two years for electronic components) and outlines the contents of the package, including the speaker baffle, grille, paint mask and mounting template. It also describes the recommended positioning for front, centre, surround and multi‑channel home‑theatre setups, emphasizing proper angles, listening height and clearance from walls or ceilings.\n\nInstallation guidance covers cavity requirements (minimum 20 L), cable selection (loop resistance below 0.5 Ω for non‑critical use, below 0.2 Ω for optimal performance), preparation of drywall or solid walls, damping the cavity with mineral wool, and the step‑by‑step fitting of the speaker. The manual also includes customisation tips for painting the frame and grille.
| Minimum mounting distance from walls/ceilings | 0.5 m (20 in) |
|---|---|
| Recommended cable loop resistance | below 0.5 Ω (non‑critical) or below 0.2 Ω (optimal) |
| Minimum cavity volume | 20 L (0.8 cu ft) |
The speakers should be mounted at least 0.5 m (20 in) away from walls or ceilings.
Use a cable loop resistance below 0.5 Ω for non‑critical installations and below 0.2 Ω for the best results.
A cavity volume of at least 20 L (0.8 cu ft) is required for proper bass performance.
