Visaton FD18 L - Back box for DL 18/2 T Ceiling Speaker
Back box for DL 18/2 T.
Using the FD 18L gives a tighter sound to the speaker and also lessens the sound transfer upwards into upstairs rooms.
Check before you order that you have enough clearance in the ceiling void to accomodate the encosure depth of 180 mm from rear of plasterboard or ceiling tile.
Speaker enclosure made of steel sheet for DL 18/2 T with two push-out holes for cables. Four mounted screws to attach terminals and cable clamps.
Sound can be further improved by using Visaton damping material inside the enclosure. You can find this in the "Accessories" section of "Visaton Loudspeaker kits".
