An outstanding choice for use in in-wall or ceiling applications such as home theatre or reticulated music systems. Features excellent hi-fi reproduction and high power handling capability.

Designed to be installed into ceilings or walls, this low profile attractive speaker system and grill will compliment a wide range of hi-fi and A/V sound systems, and can be utilised in outdoor or marine environments. The efficient polycone driver produces clear bass and midband response, while the dome tweeters provide crisp clean high frequencies. The speakers include two-way passive crossovers.

Installation is simplified by the use of swivelling mounting clamps, which rotate and then clamp onto the mounting surface as the screws are tightened.

Note:For PA or background music installations, an M 1126A (30W) or M 1130 (40W) 100V line transformer can be fitted for sound reinforcement applications.
