Bowers & Wilkins BB 6C Backbox
Best acoustic enclosure for custom in-ceiling speaker installations.
This enclosure is the secret to making in-ceiling speakers actually sound like high-fidelity audio rather than just background noise. By creating a controlled acoustic environment, it tames unwanted resonance and stops sound from bleeding into other rooms, though it does require a bit more planning during your installation phase.
