Very good product
It is essential to have an ALR screen to fully enjoy the Optoma Cinemax P2. The screen is really difficult to assemble because of the unclear instruction sheet, but it is possible to do it with 2 people. The projector offers an incredible image, the only drawback is the interface which is not great and the updates which we do not understand. As for the sound, it is correct with the integrated bar but I added a small subwoofer (Jamo Sub 210) which allows the sound to fill the room.
